Car is a 2005 XJ8L. While driving at very low speeds (less than 10 mph), these dashboard warnings come up:
- DSC Not Available
- Parkbrake Fault
- Engine System Fault
The car spontaneously goes into Restricted Performance mode. Shutting off the engine briefly and restarting clears the warnings and the car runs fine - until those fault warnings reappear a short time later.
I scanned for trouble codes. The most relevant stored code was P2135. My research indicates these three warnings are often caused by a Throttle Position Sensor problem.
I have a Denso 198500-3300 TPS on order. My question is about its installation. Are there sensor output voltage and/or resistance values that should be checked and set (by rotating the TPS during installation), e.g. at closed throttle, idle, and full throttle positions?
I want to check the existing sensor as well as the new sensor prior to installing it. I’ve searched factory service manuals but couldn’t find that exact data.
