- čas přidán 8. 09. 2024
- Infinity g35x 2007 came in with a fuel gauge non functional , every time the ignition is turned on the gauge reads Full.
Tested and confirmed the floater arms are functional with a multimeter changing resistance when the arm is moved around.
Turned out to be the AC climate control unit above the radio had 2 cracked resistors as seen in the video , some solder refresh and everything is back to normal.

Thanks. Trip to the Wreckers, a few dollars, And 15 minutes later my issue was resolved. You saved me hours and hundreds of dollars messing with fuel pumps and fuel level readers.
Im glad this has helped you !
I did the pump/sending unit replacements when my wife ran out of gas for likely the first time ever (yikes). Still reads full. We've been setting trip meter for 2 years when we fill up as a workaround. Now having possible clock-spring issues (flashing air-bag light), but the P0462 is the only persistent code showing. Regardless of current issue, I have not wanted to pull cluster, and seeing this I'm 99% sure it's the fuel gauge issue. Much appreciated! 😃
🎉 It worked thanks for this video. Saved me wasting more money at the mechanics trying to figure this out.🎉😊
Very good video, Im a mechanic and always like to repair rather than replace. This fix worked great.
Thanks brother. I did initally replaced my passenger side fuel pump on my 2012 fx35 due to inaccurate fuel gauge issue I had. Also, because the car is old so I thought the fuel pump and levelling sensor showed some signs of malfunctioning. However, the the replacement, fuel gauge is the same. It doesnt go down past 3/4. Finally, CEL came on with this code. followed your tip and found one resistor with cracked solder. Resoldered it and now it's all good again. More power to you! God bless❤❤❤
Thank you very much for helping to solve this problem once and for all. Opened everything up and soldered up those old resistors. Specifically it seems it was the 161 as you showed. Damn thing came off at first so I knew it had to be it once soldered down. Cleared the code and fueled back up. Finally good to go! Feeling extra empowered with this fix 🤘🏽
Thank you , im glad you got it going.
Thanks bro did the fix.
My favorite all time car repair video
So glad I came across this!!!! I tried just to unplug the sending units, and no change on gauge. Found this video, BINGO, that was the issue. Soldered those resistors again an gauge works. I had a harder time finding this video again to say Thanks for sharing your knowledge! Now I have to put my rear seat back together. :-) Gauge died at 258000 kms. And after 2 run out of gas events... had to fix it!
Im glad this video helped you !
Had a good laugh when I went to drive the car. Couldn't get it into drive. There is a plastic piece that slides under the selector that the part that attaches the knob didn't go through properly, and only allowed me to go from park, reverse, and neutral. But not any lower. Just popped it all off and then stuck the stick in the right hole. ;-) there's a joke in there somewhere....... .... ..
Thanks a million ..i used 4× glasses a little old scool flux to hold the tiny piece of solder with a tweezer..got the digital iron dead right.only stayed on the spot for a second..its all set now your good schematics i can tell.
Thanks for that video helped me a lot on a car I was stuck on.
I been looking for a fix for my situation for so long you just saved me hundreds of dollars thank you so much!
Glad i could help !
Thank you soo much! I had the same P0462 fuel sensor code on my 2008 G35 and it caused the check engine light to come on . I was gonna replace the fuel pump and fuel sensor but I decided to replace the ac amp control module first before messing with the fuel pumps. So i bought a new ac amp control module from Infiniti and replaced the old one and my check engine light went off and it cleared the P0462 code I had for several months and the fuel gauge is working properly now. I’ll probably wait until I get another fuel sensor code to replace the fuel pump and fuel sensor. I have about 200k miles on my G
HOLY CRAP..... this fixed my issue!!! THANK YOU!
Mine didn’t
@@rapongga28 Spoke too soon, now i'm having a totally opposite problem..... my gas gauge moved up and down, but its telling me that i'm running out of gas much quicker than normal. Say, i drive for 100 miles on a full tank and it says that ive used half my gas tank... which is weird because 100 miles onmy tank is literally a quarter not half, i know because i reset my odo everytime i fill up... so yeah... i guss this is better than what i had before when it said i was full all the time... lol
Dude respect to you helping the g community keep these cars on the road man. New sub here for the simple fact that what you did here deserves a sub !!
Hi, thank you for finding the solution that even the dealership have no idea how to fix this ugly Infiniti gas gauge problem.
I would really appreciate it if you could help me with my issue after doing this repair.
I have 09 G37x coupe, the only thing wasn’t working is the gas gauge, and the check engine was on for this issue only. Gas gauge was stuck all the way to full and never change.
This morning I saw your video and I decided to give this a try. So I followed your steps and got the module out and went to an electronic repair shop and he soldered 4 resistors ( three of them marked (161) and one marked (181))
The guy soldered all 4 resistors and tested all of them and test passed.
Went back to my car and installed the module and the gas gauge is fixed and no more check engine light.
But
Now I have multiple issues: the speed gauge is not working right and changes very slowly and doesn’t give you the right reading of your speed, also the rpm is doing the same thing, and I have the TPMS is on and the air bag warning is on.
Thank you
Where is this module located on a 2005 Infiniti G35 Coupe?
Did you find it ?
Yup so I’m here just to verify this video. He’s right, I have changed both my fuel pump (right back seat) and fuel sending unit (left back seat) but still the problem wouldn’t go away and my gas gauge still stuck at the middle of the gas tank and wouldn’t move any further downward. Just change the AC module control unit and it should be working. Most G37 and G35 have this same type of problem and usually it’s not bc of the Fuel Pump units so yeah if you’re having this type of a problem, just follow this guy or buy a new ac module control unit (the white board) like what he shown in the video.
what about a G35 coupe 2006? its different , does it even have the same ac amp?
@@realmadridFS7 I believe that would be a different one though they all look kinda the same. However this problem often occurs on the G37 platform usually from the year of 2011-2013. It could be one of these 4 main problems
1/ Fuel Pump (located on the right back passenger seat).
2/ Fuel Sending unit (located on the left back passenger seat).
3/ AC amplifier module control (behind the Center Dashboard).
4/ AC compressor.
That's as far as I know but these should be the main problems you should look for before getting a G37. Overall it's a very fun and durable car to drive and cheap to maintain.
@@corvoattano3327 I have a G35 Coupe 2006 and ive already fixed the fuel pump , fuel sending unit and even got the cluster rebuilt and still have the same problem with the gas gauge
@@corvoattano3327 i just cant seem to find a decent video of a g35 coupe procedure or someone tht would reply, lol thanks for replying , been tackling this problem for months now
@@realmadridFS7 No problem bro. Yeah it's frustrating. My G37 has the exact same problem even after I changed both the fuel pump and the fuel sending unit. Actually it was having a problem starting up and one day it just died in the middle of the road. Turned out it was bc of the old Fuel Pump that needed to be replaced and replace it I did. However the fuel gauge stopped working properly AFTER I changed the Fuel pump so Im looking to buy a new AC amplifier to see if the problem could be fixed next month
when I smack the top of the cluster the fuel level reads properly but not all the time could that rule out that the cluster is the problem?
I ordered me a used control module from ebay... hopefully that fixes my 3 quarters full issue.
My gas gauge somewhat works ,when it fills up and go to far above full that’s when I get the 0462, but when it gets down to full, the code goes away if I clear it, then it’s kind of wacky from full to a half a tank sometimes it’ll read correct sometimes it won’t but when it gets down to a half a tank it starts reading correctly.
glad i seen this comment, mine was fine until i filled it up and the morning after i got the service light on, still hasn’t moved but hopefully in my case it’ll turn off cause i’m super anal abt that
Great tip we appreciate it 🥋
Thank you
After I change my fuel pump twice i'm finding out about this 😮💨
I did the same thing. I changed both sides of the fuel sensors.
I was having the same issue replace both fuel pumps tried doing this but I removed the module but the chips or not broken. What other issue can it be?
could you do a video for a g35 coupe pls
I have the same code on my 2003 maxima change the pump and sending unit still have the code.. does the 03 maxima have this module? And could this be the culprit for the code?
I have a problem with my a/c in my infiniti fx35 09 some body tell me this module is the problem becouse the a/c sometimes cold sometimes hot
Hey, I have the same exact car and my ac compressor doesn't wanna turn on unless i use some bypass in the diagnostic mode, and i had a shop tell me its either my ac amplifier, or the low pressure switch on the condensor, have you ever had this issue or have any insight? It's either one of those causing my problem and not sure what's more likely. Thank you!!
So I had to get a jump start a few days ago. But recharged my battery because I have a draw if I don’t drive for a few days. But my problem I’m having is after putting battery back in none of my gauges work nor the beeping noice I’m supposed to get when key is in ignition. Only lights I get on dash is brake light air bag none of my other indicators work but are fully functioning wondering if I shorted that ac amplifier when getting a jump cause my fuses were fine I never thought about that being the problem where as I hooked up fire stick to my screen few months ago
I have read but lost the info in my service manual that the later or earlier models are wired to the ac auto amp but the other year g35s are NOT and they are wired from the fuel senders to the cluster itself directly. This can quickly rule out if its a cluster or ac auto amp issues. Can you or anyone please verify which years g35 had the ac auto amp wired to the circuit and which DIDNT? i really dont wanna have to pull out the ac auto amp AND the cluster if one doesnt work. Its enough work as is.
This should help on the 2006+ M35 Y50 right? Help with the fuel issue? Gauge stuck
Would this fix my AC fan blower not coming on? I have been told I need a new Amplifier Climate Control
I have an aftermarket interface due to an aftermarket stereo I believe it’s a Metra, which has that climate control unit. Could that be a problem with my fuel gauge I’m sure it’s not near the quality of the OEM climate control unit.
would this procedure work the same with a G35 coupe?
it's all the same
Thank you for this video. I followed your video and the OBD2 code is gone and the guage cluster now reads correct fuel levels. But now I have a completely dead TPMS system, no live data from any of the sensors when I plug the scan tool and the TPMS icon stays on all the time despite good pressures in all tires. Any chance the same module is also responsible for TPMS communication? any other thoughts?
Was the TPMS system functional before you do the fix ? If so it might be related to the same module. Look for other cracks
I have a 2006 G35 Coupe, and my TPMS stopped working years ago. I went to a Local Tire dealership and they replaced all 4 for around $40 each.
I'm having an issue with my Fuel Gauge, it stay stuck at 3 quarters full, doesnt go any lower than that... lol I changed out the Sending unit and Fuel Pump with OEM parts and still same issue.... I'm curious as to how does rthe Temp Control Unit controls the gauge? And if i need one, i can swap it out myself... for reference i have a 2010 FX35... no codes.
Thanks. This worked for us too.
What type of control module
climate control module
Will that give you a check engine light?
Hi I have a fx35 2010 and I’m havin the same situation already put a new gaz pump in it and the code still there and impossible to erase . You got a g35 in the video by luck it would be the same system for my fx35 . Thx
So I own a 2011 Infiniti FX35 and I had the same problem with my fuel gauge and error code p0462 for the last 6 years. I did changed the fuel pump and that didn't solved the problem. Thanks to this video I decided to try this solution and it worked. I bought an used module since I didn't want to solder. I followed the same steps to get to the module. It took me about an hour to replace the module and put everything back in place. It was an awesome feeling to see the actual amount of gas in the car and the check engine light go off. Thanks a lot for this awesome video.
Wheres the best store to get flux from
Hello I got a 1999 Dodge ram 2500 with the same issue my fuel gauge reads empty and gas light is on I replaced the fuel pump and sending unit and the cluster and the module ????
???????? This video is about an Infiniti . Not a dodge
Does this apply to the 06G 35 coupe A/T
I would love to know the answer yo that question as well. I have a 05 g35 coupe auto and it has the same problem. I’ve been trying to figure out if it’s would be the same on our coupes
Yo i got a 06 G35 coupe too have yall fixed it?
bump
Its best to check if your model has the same module located in the same area , if it does then yes it applies.
@@MuLife what year is the one that you’re working on so I can look it up I’m not just gonna go rip in my dash apart to find out
I just did mine and now the needle reading E and it was at F 🤦🏾♂️
Hi if you are in Toronto I would pay you to do this
I have 1 of these i order from sacc however i sold my car i will sell 1 Ac amplifier 1 fuel pump 1 sending unit,
My gauges aren’t working after changing my battery terminals but everything is fully functioning just no gauges indicators for signal and headlights not working along with the illumination on the cluster and clock ac buttons or beeping noice I changed the a/c amplifier and nothing changed so I put the old one back

Where are you located?! Can you fix mine?! lol
Located in Ontario , Canada. You can send me the module for repair. Contact details in description.
thank you! I thought I heard the CA accent! :) Can the car operate without that? I have no other options for transportation. :(@@MuLife
@jenniferrupe9804 i believe the car should still run , but you may lose some functions. Best to remove the module and test.
