Pre catalyst and Mid catalyst sensors

WARNING: This page is about a different variant/trim than selected.

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. (When 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).
