Principles of Operation

For a detailed description of the intake air distribution and filtering system and operation, refer to the relevant Description and
Operation section of the workshop manual. REFER to: (303-12D Intake Air Distribution and Filtering - V8 S/C 5.0L Petrol)

Intake Air Distribution and Filtering (Description and Operation), Intake Air Distribution and Filtering (Description and Operation), Intake Air Distribution and Filtering (Description and Operation).
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
Hoses and ducts (damage/connections)
Air cleaner element (contaminated/blocked)
Restricted air intake
Supercharger
Supercharger (cooling fan) drive belt
Supercharger seals and gaskets
Charge air coolers (damage/connection)
Mass Air Flow (MAF) sensor
Manifold Absolute Pressure (MAP) sensor
Manifold Absolute Pressure/Temperature (MAPT) sensor
Throttle body
Harness (security/damage)
Connections (security/damage)
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.

Major air leakage (after the
supercharger) Check the supercharger and drive belt. Remove the supercharger drive
belt and recheck for noise. Turn the supercharger by hand and check
for excessive resistance. Check for excessive play at the supercharger
pulley. Check the charge air coolers. Refer to the relevant workshop
manual section.
