where is the TPS(throttle positioning sensor) on a 2001 volkswagen 1.8t?
Im got a check engine reading for TPS malfunction and air fuel metering malfunction. The TPS is a throttle control sensor but i cant seem to find it. Nothing comes up online and the "oh so helpful" people at auto zone dont know $&*@ about euro cars. The air fuel problem seems to be the mass air flow sensor...right? So if someone could please tell me where the throttle positioning sensor is it would be much appreciated.

TPS is built into the Throttle body...

Idon't know much about volkswagons, but i've worked on many different vehicle's and everyone that i've worked on has had the throttle position (TP)sensor mounted into the side of the throttle body (carb).It should also be on the side that the throttle cable is hood to. There's usually two sensors side by side and one of them is the throttle position(TP) sensor & the other one is the idle air control (IAC) valve assembly . It's bolted in by two screws & has a wire plug going to it.Source(s): 30 years experience working around vehicle's.
