Powertrain Control Module

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.

The Powertrain Control Module (PCM) is installed in the rear left corner of the engine compartment.

The PCM has the capability of modifying its fuel and ignition control outputs in response to several sensor inputs.

The PCM receives inputs from the following:

Crankshaft Position (CKP) sensor
Camshaft Position (CMP) sensor (4 off)
Engine Coolant Temperature (ECT) sensor (2 off)
Knock sensor (4 off)
Manifold Absolute Pressure (MAP) sensor
Manifold Absolute Pressure and Temperature (MAPT) sensor
Mass Air Flow and Temperature (MAFT) sensor (2 off)
Charge air temperature sensor
Throttle Position Sensor
Heated Oxygen Sensor (HO2S) (6 off)
Accelerator Pedal Position (APP) sensor
Ambient Air Temperature (AAT) sensor
Fuel Rail Pressure and Temperature (FRPT) sensor
