Heated Oxygen Sensor (Ho2S) And Mass Air Flow And Temperature (MAFT) Sensor

WARNING: This page is about a different car, the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, 2016 Land Rover Range Rover, 2014 Land Rover Range Rover, and 2013 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.

There are several adaptive maps associated with the fueling strategy. Within the fueling strategy the Powertrain Control Module (PCM) calculates short-term adaptions and long term adaptions. The PCM will monitor the deterioration of the HO2Ss over a period of time. It will also monitor the current correction associated with the sensors.

The PCM will store a fault code in circumstances where an adaption is forced to exceed its operating parameters. Simultaneously, the PCM will record the engine speed, engine load and intake air temperature.
