Code P0120

Our 02 3.4 Tacoma threw this TPS code today. I have searched and read a bit on here, but couldn't find what I was looking for.

I cleared the code and it hasn't come back, but I've only driven about 15 miles. I did clean the intake and butterfly area with carb cleaner. The truck seems to run fine except that it idles at 900 rpm warm. I read some posts suggesting that you remove the TPS and clean it. I have some MAF cleaner that would probably work. But if I remove the TPS, do I have to readjust it with an Ohm meter? Not sure I want to get into that.

Also, I read several posts about also cleaning the Idle Air Control. Where is that? I've done it on the Subaru, but never on the Tacoma.

Thanks for any help you can give.

 

No adjustment for a clean MAF. Use the throttle body cleaner on MAF and IAC. IAC is on the throttle body. It opens and closes a passage past the throttle.
Don't use carb cleaner. It will eat seals.

 

Thanks, yes, i should have specified that I used throttle body cleaner. Also, I used MAF cleaner on the MAF. I was asking about adjustment if the TPS is replaced, not if the MAF is cleaned.

I went out and cleaned everything again. I found the IACV, but did not want to remove it unless I have to. It is late, and a storm is on the way. Anyway, it was still idling at 900 - 1000. I then reset the ECU, and it immediately dropped to 650. We'll se if it stays. I would still like to know about the procedure for R&R on the TPS just in case.

Thanks
