Pre Catalyst and Mid Catalyst Sensors

WARNING: This page is about a different car, the 2013 Jaguar XJ, 2012 Jaguar XJ, 2011 Jaguar XJ, and 2010 Jaguar XJ. However, it is still accessible from the selected car via links, so may be relevant.

Drive the vehicle until the engine is fully warm (greater than +80 °C). The drive cycle should include driving the vehicle in a steady throttle condition at a road speed of 30 mph or above for a duration of at least 2 minutes. (Once functional the oxygen sensor output signal can be seen reacting to changes in engine speed/load or if the sensor is faulty a DTC(s) will be raised).
