Possible Causes
WARNING: This page is about a different variant/trim than selected.
NOTE:
Exhaust gas temperature sensor - Post catalytic converter sensor rationality check during a driving cycle is not plausible (compared against a temperature model). Exhaust 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, a malfunction is raised
