Throttle Position Sensors
WARNING: This page is about a different car, the 2011 Jaguar XK and 2010 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.
The throttle position (TP) sensors allow the engine control module (ECM) to determine the position and angular rate of change of the throttle blade.
There are two throttle position (TP) sensors located in the electronic throttle. See below for details of the electronic throttle.
If throttle position (TP) sensor fails, the engine control module (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 throttle position (TP) sensor, the engine will suffer from poor running and throttle response.
