Engine Emission Control

Engine Emission Control - VIN Range: N52048->N99999

Overview
There are changes to the engine management system (EMS) for 2006 my, the most obvious of which will be the change to 7-digit diagnostic trouble codes (DTCs) from the familiar 5-digit, and the introduction of secondary air injection.

Inspection and verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.

Mechanical Electrical
Engine breather hoses Fuses
Cyclone separator Wiring harness
Exhaust gas recirculation Loose or corroded
(EGR) pipes (check for cracks) electrical connectors
EGR valve Sensor(s)
Stepper motor(s)
Secondary air injection pump
Secondary air injection control valve
Engine control module (ECM)


3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the cause is not visually evident use the Jaguar approved diagnostic system or a scan tool to retrieve the fault codes before proceeding to the diagnostic trouble code (DTC) Index.
