Throttle Position Sensors (TPS)
WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
The TPS allow the ECM to determine the position and angular rate of change of the throttle blade.
There are two TPS located in the electric throttle. See below for details of the electric throttle.
If a TPS fails, the ECM:
- Adopts a limp home mode where engine speed is limited to a maximum of approximately 2000 rev/min
- Discontinues evaporative emissions control
- Discontinues closed loop control of engine idle speed.
With a failed TPS, the engine will suffer from poor running and throttle response.
