Possible Causes
WARNING: This page is about a different variant/trim than selected.
NOTE:
Exhaust gas temperature sensor temperature is checked during a vehicle driving cycle against a model temperature for rationality. Some engine speed/load conditions apply. If the difference between the sensor temperature and the model exceeds a defined threshold, the DTC is set
- Electrical Cause
- Yes
- Mechanical Cause
- Yes
- Control Module Cavity
- Circuit reference I_A_CATTSPRE2
- Circuit reference G_R_CATTSPRE2
- The powertrain control module detected plausibility failures
- Exhaust gas temperature sensor - Pre catalytic converter circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Exhaust gas temperature sensor - Pre catalytic converter failure
