I caused some damage to my TPS senor a few weeks back. Was getting a code 7, so had to put on a new one on and calibrate it. Might as well throw together a video and here ya go.
I can’t thank you enough my car has a check engine light on and it read the same code as the throttle position sensor and your video just saved me a hole bunch of time I really do appreciate it
I would not suspect the stalling in gear is fuel related. Easy to open the maintanace port on the fuel rail when it stalls. If fuel shoots out its not the fuel pump or filter.

My cb7 has had a surging idle from before that would come and go on warm up. A couple days ago I exited the freeway and at a stop the car now goes below 700 rpm at a stop and surges between 650-750 and seems likes it’s trying to catch itself. Car is fine on cold starts but the low idles happen after a bit. Do you think it is the iacv?
Could be. Eric The Car Guy has a good video for that on here. He covers both IACV and the FICV. czcams.com/video/L788jKEVblY/video.html There are any number of vacuum leaks that could contribute to this as well. Do a google search , "cb7tuner idle". Lots of good reading there. Has the car had a good tune up? Like plugs, wires, air filter ect. Good luck! Hope your able to track it down.
Dreamability Awesome, thank you. Yes, car had complete tune up done 2 years ago and was doing great and would idle surge here and there but after the freeway drive, began to idle low in drive, strange. I purchased a new iacv and hoses and will replace later this week, hopefully that will do the trick.
Hello. You don't measure from the battery. You measure from the red wire going to the TPS sensor. Measuring from the battery is giving you the battery voltage not the TPS voltage. Hope that helps. Later
@@henryepps7811 it's been a while since I've done that I'm not certain but is there any possibility you've got it flipped all the way around backwards or anything lol. Like I said it's been a while since I've done one and it was just a thought I'm not sure that's even possible without having one in my hands
Dreamability my son just bought but a 93 accord when we press the gas it revs to 3000 doesn’t go past it and after a while it will go normally, and we can go past it any ideas?

I have no idea. Best guess maybe the TPS is installed wrong or is bad. @14 volts, are you sure your meter is on the right setting? Sorry I couldn't be more help. Let me know how it works out. Good luck.
Those are just the measurements specifically for my Honda engine and TPS. Im sure your Toyota engine would have different voltages. Check online or call a dealer.
Yeah that would be bad and should be too difficult to get that other 0.05. mainly an issue because that's the car's understanding of where the throttle position is at so where you've got it set at it thinks it's somewhere else and it's not going to be delivering the right amount of fuel to the air ratio
@@frnklin1915 Yes, that is probably it. Or you could have a vacuum leak on your intake. Also the o-ring on the idle speed adjustment screw has been an issue lately in several I've worked on. Might check that. Also set your base idle. But first get that TPS sensor set right 👍
Yes, you need the voltage meter to calibrate it so the ECU knows the correct position of your throttle. You can get this exact one at harbor freight for like $5 bucks.
@@jessedachosenone3339 lol guess so. Sure, it'll "work" without calibration. However the computer is not seeing the actual correct position of your throttle plate. The results can range from poor fuel economy, idle surge, loss off rpms or top speed, the engine running rich or lean,(can damage internal short or long-term), and possible idling issues depending on what range it is out of sync just to name a few. But maybe it's in just the right spot and your good to go. Best of luck 👍 Later.
I do all my own car repairs. I watched several videos on this. Yours is the best. Thank you!
Thank you!!! I followed your directions and was able to repair my daughter’s Honda and save some money doing it myself. Thanks!!!!!
I can’t thank you enough my car has a check engine light on and it read the same code as the throttle position sensor and your video just saved me a hole bunch of time I really do appreciate it
You're welcome! Glad to hear that. Later
My car has the same defect. Now I know the solution! Thank you!
Your motor looks beautiful from what i can see
So good bud. Can’t thank you enough
You welcome man, I'm glad it was helpful 👍
Great info!
Great explanation!
What settings do you use on the voltage meter?
20 DCV
@@dreamabilityCB7 : Thank you. Your video was most definitely helpful
When closed it should have 0.45volt and open 4.5volt right?
If you know the voltage can't you just set the resistance on the TPS sensor
I have a 1990 accord that I replaced a fuel pump on with filter now car fires and will drive ok cold but once warm it stalls in gear
I would not suspect the stalling in gear is fuel related. Easy to open the maintanace port on the fuel rail when it stalls. If fuel shoots out its not the fuel pump or filter.

@@abtransport13 did replacing the iacv fix your problem?
How critical is it to get exact 4.50 I got mine at 4.51 is that ok
If you can't dial it in exact I'm pretty sure that 100th of a point isn't going to hurt ya. 👍
I’m doing tps replacement and my volt meter is reading it from 12.45-10 volts going from positive terminal on battery any ideas brand new sensor
Hello.
You don't measure from the battery. You measure from the red wire going to the TPS sensor. Measuring from the battery is giving you the battery voltage not the TPS voltage.

@@dreamabilityCB7 yeah I probed the red wire on tps where would my ground go to
@@henryepps7811 any solid ground off the engine block or chassis

Do you touch the red meter wire to positive battery terminal?
No, it goes to the red wire on the sensor. Then ground wire to any ground.

Dreamability no, no engine light on
What does it mean when u go to measure volts and it's @14 and open it drops
I have no idea. Best guess maybe the TPS is installed wrong or is bad.
@14 volts, are you sure your meter is on the right setting?
Sorry I couldn't be more help. Let me know how it works out. Good luck.
Why icant get 4.5 when fully open?? My engine 4AFE..
Those are just the measurements specifically for my Honda engine and TPS. Im sure your Toyota engine would have different voltages. Check online or call a dealer.
A question what happens if I leave the calibration at .40 is that bad ??
Yeah that would be bad and should be too difficult to get that other 0.05. mainly an issue because that's the car's understanding of where the throttle position is at so where you've got it set at it thinks it's somewhere else and it's not going to be delivering the right amount of fuel to the air ratio
