Engine Control Module (ECM)

WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

The ECM is installed in the front passenger side of the engine compartment, on a bracket attached to the engine bulkhead.

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

The ECM receives inputs from the following:

CKP sensor
CMP sensors (4 off)
ECT sensors (2 off)
Knock sensors (2 off)
MAP sensor
MAFT sensors (2 off)
MAPT sensor
Throttle position sensor
Heated oxygen sensors (6 off)
APP sensor
Ambient air temperature sensor
