Transmission Fluid Temperature Sensor Monitoring
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2008 Jaguar S-Type, 2007 Jaguar S-Type, 2006 Jaguar S-Type, 2005 Jaguar S-Type, and 2004 Jaguar S-Type. However, it is still accessible from the selected car via links, so may be relevant.
The TCM monitors for faults associated with the transmission fluid temperature sensor in the following ways:
- Open and short circuit fault detection.
- The temperature cannot alter by more than a predefined differential between any two consecutive measurements.
- The transmission fluid temperature must rise after the engine has been started provided that the fluid temperature was low enough to begin with (The vehicle must be driven and the diagnostic test condition met).
