Post catalyst sensors

WARNING: This page is about a different car, the 2015 Jaguar XK, 2014 Jaguar XK, 2013 Jaguar XK, and 2012 Jaguar XK. 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.
