- Doing this install on 2012 VW Jetta 2.5L SE car went into leap mode throwing EPC Engine Light on the dash. Connected My OBD Scanner to the car and had this code P0122 Throttle/Pedal Position Sensor/Switch A Circuit Low Code. So instead of taking it to dealer and paying and arm and leg decided to do myself. So if anyone is having same issue, Me changing the throttlebody did resolve and fix the issue. Hope this was helpful to anyone with same issue.

Thank you so much for this video! I watched your and another's body shop video to replace my throttle body in the same car. The body shop was using all kinds of tools that I don't have but you were using tools, that I do have. Thank you for saving me time and money!!
So glad this helped you and saved you money. That makes me happy that my video can help. Thanks
Thanks for making a video with so much detail. Glad the fix worked...hope it works for me!
Thanks Jerry hope it works out for you as well.
Thanks a lot for posting! I'm about to dive into replacing mine and this helped me know what I needed to complete this. Thanks!
My pleasure
Thanks for this. Just finished trading out mine with the Amazon model you linked to. EPC and Check Engine light were on, and it was in a bit of a limp mode with limited power above 2,000rpm.
After changing, first start didn't work but on the 2nd try it fired right up. EPC light went out, but CE light is still hanging around. I'm guessing that it'll clear after a few more run cycles. The re-learn procedure in the comment from THXFXR didn't seem to do anything for me - I never got a 'Bing'. I don't know if it made any difference, but removed the negative cable from my battery while i did the work.
Hardest part for me was removing the engine cover (gloves help with this) and dealing with the fuel supply line. Everything else was relatively easy, and I'm not a particularly skilled, experienced or well-equipped car mechanic. I took my time and was very careful to avoid dropping any fasteners or tools.
Torx T20 bits got the airbox parts off and a T30 got the throttle body off. You'll want a couple of different nut driver options as mine was a little too long for a couple of screws. Fortunately I was able to improvise.
I'd suggest maybe swapping spark plugs out while you're doing this since you'll have the engine cover off anyway. That was pretty darn easy and only took an extra 10-15 minutes.
thank you for this video. you saved me $1300
That's awesome! This is what the video was intend for to help you guys. So glad it saved you those $$$
Man the stealership is crazy thinking this is worth $1360 worth of work 😂
It's a real simple job if you do it yourself
The dealer was charging me 1200 bucks, after this video I replaced the part with 200 dollars, only I have the reset my car.
Thanks for this. Most helpful tip was how to release the electrical connector. Install pretty easy. I have a short ram intake, so much easier to access everything. BTW: for the naysayers.....if you disconnect the batter while you install, the ECM will self calibrate.....you do not need a VAC-COM. Don't freakout when you start engine and every warning light is lit. As soon as you drive vehicle, they will all disappear. Ohhh some vids showing install on earlier models show coolant hoses going to the TB. The '12 doesn't have these.
First....thanks for reply and sorry about typos. Hey.....I have a crazy notion. I think that maybe these things can gradually fail over time. Assumed due to sudden power loss, it was nearly 'all or none'. I did a search on this and best I could find, is milage could be lowered. (mine did get pretty poor milage...but I drive like an idiot..😆) However, w/ new part car runs better than ever. I have an IE stage one tune. With a lot more torque, always had a lot of midrange punch......now feels like even more. The tune takes redline to 7200 and used to not hit before shift....now it will easily. Any thoughts? My car is easily as quick as a stock GTI of the era. (It also has a GTI suspension and brakes)
You don’t need a vagcom nor do you need to disconnect the battery to do this. This is speaking for a 2012 Passat 2.5 5cyl. The epc light will turn off after cycling on its own. There’s a few ways to get the engine light off;
You can take your vehicle to advanced auto parts, auto zone or wherever your local parts place is and they will clear the code free of cost. Or you can cycle your car which is usually driving it and turning it on and off through the day roughly 6-7 times and the engine light will turn off. And if you feel comfortable enough you can disconnect the battery and it will cycle through the checks and clear the check engine. If you have a vagcom on hand already then you can do what the original commenter said. Just trying to save anyone doing this repair some money.
@@Kasejeb I got the disconnect battery tip from someone else online. Besides....never a bad idea to disconnect when doing anything the involves disconnecting/reconnecting wiring. I dunno of the TB can start failing over time, as the car runs better than ever w/ new one. I have an Integrated Engineering Stage one tune, and this car is every bit as quick as stock GTI of the era.
The shop replaced mine with an aftermarket one and still had the same issue. Took it to the dealer and the said I should get a OEM one and quoted me &1300 but after this video I will just do it myself
Yeah, you can still get oem and still save a ton
Have you had any issues with the throttle body from Amazon that you installed?
@@yusufdooso4534 No problems at all runs like a champ
Hey Mark thanks for the video. Gonna be replacing the TB on my sons 2012 Passat with the 2.5. Question; will the car run normal before I get a chance to clear the CEL? I see that the EPC light went out but I won’t be able to clear the CEL until Friday. Thanks.
Not sure, just installed the throttlebody and all was good
my 2009 Volkswagen Beetle 2.5l 5cyl is throwing P0122, along with P0735. EPC light, Engine Light, Abs light, and PRNDS is lit up. Essentially in limp mode, and doesn't go into reverse. Is this all due to my throttle body?
Not sure. I would look into the P0735 Code and see if maybe another sensor is triggering the car not going into reverse. But it seems like alot going on maybe would take to have looked at by mechanic. Sorry just not sure
My 2013 Passat SE 2.5L had the engine light coming on for weeks at a time then going off for weeks for about a year. Checked the codes and indicated O2 sensor bank2 (rear). Kept driving it and finally the EPC came on - and the limp mode. Being told it's prolly the throttle body TPS causing the O2 sensor to go off? Also told that what causes this TPS fail is the PCV valve - now integrated into the valve cover - that goes bad and allows oil to accumulate inside the throttle body and into the intake manifold.- causing the sensor to eventually fail. PCV valves used to be a $20 item. Now they want like $500 for the valve cover with integrated PCV valve. Have quotes of $2k to replace all this stuff including a $450 estimate just for the throttle body and installation. They're even quoting $460 for the O2 sensor replacement! This is a $30-40 item on AMZN and the Throttle body is $60-90 on same! O2 sensor is literally just ONE bolt holding it into the exhaust pipe and an electrical connection you plug in! Man these guys WAY overcharge,..
Yeah, when the EPC light came on mine. I thought it was a lot of different things as well. And I just went ahead and bought the throttle body. And luckily that fixed my problem. Good luck with the fix. PS keep me posted and let me know if the throttle-body fixes the issue. Trouble shooting really sucks
@@markgoodwin76 How many miles have you gone on the new Throttle Body? Any additional issues since? TIA
@@tomjones3907 So my daughter has been driving the car since I put the new throttle body in and no issues so far. And it's been about 700 miles so far. But I do suggest to do your own research. Because troubleshooting is a tricky mystery that no one knows what it could be just saying because sensor can trigger the epc light as well
Hey Mark, could you share the link to the throttle body part you bought? I’m seeing some for like $60 & others for like $500+ online. I have a 2012 Jetta SEL 2.5L.
I was having this really weird thing where if I idled for a good minute, it’d have a lot of trouble shifting up but I didn’t get any lights on the dashboard - is that what happened to your car too?
No I just got a EPC Light which triggered the car to go into limp mode

Hope that was helpful
Hey Mark, dope video. Will this TB part be compatible with my 2.5 rabbit it’s an 07 ????
So when I bought this throttle body, it had a if it fit my vehicle chart. And this one did so, I'm not sure if it'll fit a Volkswagen Rabbit.
Thanks
No problem
our 2012 Volkswagen jetta started not wanting to accelerate and not wanting to go over 10 miles an hour we took to orileys to run a scan and they said throttle body sensor. is this the fix for that??
I didn't have to change any sensors. Just throttle body. My car was a manual 5 speed. As well, it did hesitate to go, but it would gradually pick up speed. But changing the throttle body fixed the issues. Hope this is helpful.
get you some ear type hose clamp pliers, keep your sanity
i used a 14mm constant tension clamp
Did you have any issues with this part after sometime or still running?
I bought the same part, replaced and after that the car got even worse rpm keeps going up and down not keeping it stable. 😕
Still running just fine
@@markgoodwin76 guess I was unlucky, I switched back to the original “broken” part and it’s better than this new one I bought
what size hose clamp did you use?
I believe I used 3/4
what size replacement clamp did you have to use for that hose
Pretty sure I use the existing clamp
So, I rewatch my video because I wasn't sure about the hose clap just to refresh my memory and I'm pretty sure it the smallest you can get at the parts store.
What was your car doing to indicate you had a problem
It triggered the epc light which made the car lose acceleration power
hey my man , where did you order that part from?
Amazon
Maybe I missed it, but did you mention where you bought this part?
Never mind. Amazon under $60
Yes, Amazon
Did it have to be reprogrammed or was it all set after install?
No reprogram just slapped it in and was all set
What tools you use?
Nut driver and Torx bits, believe it was T25 and T30 I do mention what I use in the video
Took my ol lady’s to the shop today quoted me 1180$ lmao 🤣 60$ (online) job less than 1hr got yourself a deal on my side
Yes ridiculous what. These shops will charge you.
I am having trouble finding this part online. Where did you find it under $100?
@@Kusv583 eBay has it
Would this be the same for a 2.5 golf ?
Yes, it should be
the dealer wants $750 for that part. but I found it for $250
Sweet
Where did you find the part?
19:20 …..”No good deed goes unpunished” -so true 😂
Thanks for this helpful video brother. I knew this would be a great video when I saw the Tackle Warehouse t-shirt 💪🏼🫶
Thanks hope it was helpful
