Post catalyst sensors

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Jaguar XFR, 2015 Jaguar XF, 2014 Jaguar XFR, 2014 Jaguar XF, and 2013 Jaguar XFR. However, it is still accessible from the selected car via links, so may be relevant.

Post catalyst sensor monitoring can take over 30 minutes of driving to become active if the 'dew point' has not been achieved in previous drive cycles or an EMS ECU battery reset has occurred. The Drive cycle should consist of a constant speed and load allowing sufficient heat to build up in the exhaust system.
