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.

NOTE: System on naturally aspirated vehicle shown, system on supercharger vehicle similar. 1 EVAP canister 2 Vapor pipe (filler head communication) - fuel tank to filler pipe 3 DMTL (diagnostic module - tank leakage) filter 4 Atmospheric vent pipe - DMTL pump to filter 5 DMTL pump 6 Vapor pipe - EVAP canister to EVAP canister purge valve 7 Vapor pipe - fuel tank to EVAP canister 8 EVAP canister purge valve
vehicles, a DMTL pump and filter. The vapor pipes are connected to the system components using quick release connectors.
Fuel vapor is generated by the fuel in the tank and the amount of vapor produced increases as the fuel heats up. Fuel vapor
can flow freely to the EVAP canister via the tank venting system. On NAS vehicles the vapor generated in the fuel tank during refueling flows without restriction to the EVAP canister.
On all vehicles except NAS, the vapor is restricted in its path to the EVAP canister, but can flow freely during the refueling operation to atmosphere via the fuel filler pipe opening.
The vapor passes into the EVAP canister where it is absorbed and stored by the charcoal. Because there is a limit to the amount of vapor the canister can contain, the fuel vapor is purged from the canister when the engine is running and burned in
the engine.
