Principles of Operation

For a detailed description of the engine emission control system and operation, refer to the relevant Description and Operation
section of the workshop manual. REFER to: (303-08C Engine Emission Control - V8 5.0L Petrol/V8 S/C 5.0L Petrol)

Inspection and Verification

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.

NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection
Mechanical Electrical
Exhaust gas recirculation system
Breather hoses
Positive crankcase ventilation valve
Fuel level
Fuel contamination/grade/quality
Throttle body
Fuses
Loose or corroded electrical connectors
Exhaust Gas Recirculation (EGR) 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, verify the symptom and refer to the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
