Hi all i have 94 tt auto and ive had the little niggling faults sorted which some of you my be aware of but now its still showing fault 42. the cars running ok but when i get to just after 4000 rpm and about to boost fully the car jurks really badly as though there is a fuel cut also the changing of the gears is fair more jurky than it ever has been befor. Could all this be related to the TPS ?

Any ideas ?

yes it could but it also sounds like there could be something else. download the tps diagnostic check from mkiv.com and do the multimeter tests, lets see from there.

the od light stays on if i press the od button or it flashs if its pressed again. i think i can remember so over members having this problem.

if you count the flash sequence it is showing a gearbox fault/error, again mkiv.com has the codes.

don't worry about anything else except the error codes at the moment, they need sorting first. bring all the error code details to the thread and let's have a look :)

if it is you traction position sensor or motor i have all them bits (fully working) in a box at home.

the o/d light and slip cont light flash once then two second gap then do that continusly i have checked the codes the only one showing is 41. and could i buy the parts off you to see if it is that could you send me a price.

Cheers

here is some homework for you :)

the stuff i have is for the sub throttle position sensor not the TPS. see what you find out from this procedure first.

you need a new one if you can't get it in spec. you adjust it by loosening the 2 screws that hold it to the throttle body, rotating and retightening when in spec.
