Thread: Throttle Body Cleaning--Seeking advice

03 GTP, L67, 141k miles, open cone air filter

I want to clean my throttle body. I have read and googled and youtubed too much--a lot conflicting information, hoping to find some solid advice/insight to couple seemingly basic, simple questions. FWIW, I am NOT going to seafoam the TB on the car.

1st, the throttle body has coolant ports, so is there coolant in it, that is, if I remove the throttle body is any fluid going spill out?

2nd, the throttle body has MAF sensor, IAC valve, and TP sensor, right?

3rd, I have already removed and cleaned both the IAC valve MAF sensor, but I am unsure about the TP(?) sensor. Should I be concerned about fouling out the TP sensor if leave it in TB while I spray it with TB cleaner? Does removing/replacing TP sensor require PCM or other calibration, relearning, programming, whatever?

I know, total noob questions. Like I said, I've come across all kinds of conflicting info. Today is the perfect day for this, except I have commitments tonight and can't be without my only car. Thanks in advance!

You can leave the tps in. There will be a very slight amount of coolant come out but don't worry about it.

Thanks dsmuts! That leads to a follow up. Wouldn't removing the TB then require bleeding the coolant to remove air pockets?

No it'll be fine

Great.
THANKS again

The OP is supercharged. This method wouldn't be beneficial to him as the carb cleaner might eat away his rotor coating.
