Engine Control Module
WARNING: This page is about a different car, the 2015 Jaguar XK, 2014 Jaguar XK, 2013 Jaguar XK, and 2012 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.
The ECM is installed behind the suspension turret on the LH (left-hand) side of the engine compartment, on a bracket attached to the longitudinal and the wheel arch apron panel.
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 (crankshaft position) sensor.
- CMP (camshaft position) sensors (4 off).
- ECT (engine coolant temperature) sensors (2 off).
- Knock sensors (4 off).
- MAP (manifold absolute pressure) sensor.
- MAFT (mass air flow and temperature) sensors (2 off).
- Throttle position sensor.
- Heated oxygen sensors (4 off).
- APP (accelerator pedal position) sensor.
- Ambient air temperature sensor.
- FRP (fuel rail pressure) sensor. For additional information, refer to FUEL RAIL PRESSURE SENSOR (Fuel Charging and Controls).
- Engine cooling fan. For additional information, refer to COOLING FAN (Engine Cooling).
- Stoplamp switch. For additional information, refer to ANTI LOCK CONTROL - STABILITY -- XK/X150 (Stability Assist).
- Speed control cancel/suspend switch. For additional information, refer to SPEED CONTROL - V8 N/A 5.0L PETROL/V8 S/C 5.0L PETROL
- Oil level and temperature sensor. For additional information, refer to OIL LEVEL AND TEMPERATURE SENSOR (Engine).
- Fuel LP (low pressure) sensor. For additional information, refer to FUEL LP SENSOR (Fuel Tank and Lines).
- Fuel pump driver module. For additional information, refer to FUEL PUMP DRIVER MODULE (Fuel Tank and Lines).
The ECM provides outputs to the following:
- Electronic throttle.
- Main relay.
- Heaters elements of the heated oxygen sensors (4 off).
- Fuel injectors (8 off). For additional information, refer to FUEL INJECTORS (Fuel Charging and Controls).
- Ignition coils (8 off). For additional information, refer to ENGINE IGNITION - V8 5.0L PETROL/V8 S/C 5.0L PETROL -- XK/X150 (Engine Ignition).
- VCT (variable camshaft timing) solenoids (4 off). For additional information, refer to VARIABLE CAMSHAFT TIMING SOLENOIDS (Engine).
- Camshaft profile switching solenoids (2 off). For additional information, refer to CAMSHAFT PROFILE SWITCHING SOLENOIDS (Engine).
- Variable intake system tuning valve. For additional information, refer to INTAKE AIR DISTRIBUTION AND FILTERING - V8 5.0L PETROL -- XK/X150 (Intake Air Distribution and Filtering).
- EVAP (evaporative emission) canister purge valve. For additional information, refer to EVAP CANISTER PURGE VALVE (Evaporative Emissions).
- Engine starter relay. For additional information, refer to STARTING SYSTEM - V8 5.0L PETROL/V8 S/C 5.0L PETROL -- XK/X150 .
- Engine cooling fan. For additional information, refer to COOLING FAN (Engine Cooling).
- Generator. For additional information, refer to GENERATOR (DESCRIPTION AND OPERATION) (Generator and Regulator).
- HP fuel pumps. For additional information, refer to HIGH PRESSURE FUEL PUMPS (Fuel Charging and Controls).
- Fuel pump driver module. For additional information, refer to FUEL PUMP DRIVER MODULE (Fuel Tank and Lines).
- DMTL (diagnostic module - tank leakage). For additional information, refer to DMTL PUMP OPERATION (Evaporative Emissions)
