Hi all, I was wondering if it was possible to check a throttle Position Sensor with a volt meter before changing it to confirm there are issues with it. Code reader says it is the problem, but I was wondering if the Throttle body itself was in need of a clean could this be pointing me in the wrong direction. Is it possible a dirty throttle body could do this.

can test with a meter but can be cleand out with som switch cleaner, take it off  mark where it was on intake, and there is a hole that you can spray it in and give a good shake then leave to dry out before putting back on.

Do you know what readings I should be getting?

i cannot remember, but putting the meter on the pins and move the knob round by hand and it should go up and down in resistance smoolthy. there is two side to it top mid and bottom mid is the feed top  and bottom is for reading resistance.

Update, I had a bit of a panic on due to having to try and get the car through the MOT, which was'nt going to happen with the engine management light on. However, before diving into the wallet we swapped the new Cam Sensor with the old one which was replaced because of a Cam Sensor code previously. For whatever reason the car instantly ran better, engine warning light is out and straight through the MOT without any advisories   My plan now is to strip the thottle body and clean it as we still have codes relating to the throttle body (throttle body sensor and throttle position sensor) although nothing got in the way of the MOT I'm assuming they will show themslves again. Am I following the right course of action, any other suggestions welcome. Also, is there anybody with a Tech2 in my area, South Devon

Yep, TPS codes are normally down to gunged up T/B

^^^^^

What rob said P1555 IIRC on a 2.2 is normally a gunged up throttle body, might as well do the breathers as well, worked for me
