Tps

[bastianshaw]

Im not getting a response from the stomp test indicating the tps; is the TPS serviceable or do I need to just replace it?

Replacement is best. They are really hard to put back together.

MAke sure you are correct about it being a faulty TPS by testing it with a multimeter.

Is the TPS directly related towards why a stomp test won't work?
Just found out a week ago mine doesn't work either.
I also have first-start idle problems.. so....

Yeah if the TPS doesn't work then the ECU will not know you are "stomping".

Crap.

Thank you sir.

I read they fill w oil? I was gonna drill a small hole then reinstall

Save yourself the headach and replace it. I need to do this to my m50 as well. Stomp test does nothing on mine and I have intermittent driveability issues occasionally.

hard starting?

No, seems to cut out a little. Completely random too.

I pulled 2 throttle bodies recently, replaced the TB heater gasket, etc and drilled the hole & cleaned the TPS with electric contact cleaner. It seemed to help plus I found out one was dead on WOT. Its $3 in gaskets and maybe half an hour

Yes the TPS will cause hard starting, idle issues, no stomp test, and a variety of other problems.

Replacement is usually not necessary unless you verify it is adjusted correctly first. Check with the Bentley repair manual on how to adjust and test.

The TPS is correctly adjusted if the idle switch closes when the throttle arm is 1mm off the stop screw. You can't just by the click and need to use a meter or test light to tell when the idle switch closes.

^Good point!

Is the TPS usually adjusted within spec out of the box?
