PINPOINT TEST A : TEST
CONDITIONS DETAILS/RESULTS/ACTIONS A1: CHECK FOR COOLING FAN RELATED DTCS
NOTE: For a complete list of all diagnostic trouble codes that could be logged on this vehicle, please refer
to section 100-00. Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the
5 digits from the scan tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits
give extra information read by the manufacturer-approved diagnostic system). 1 Using the manufacturer approved diagnostic system check the engine control module for DTCs 2 P0480-00 & P0480 with any other different last 2 digits in the DTC 3 P0481-00 & P0481 with any other different last 2 digits in the DTC 4 P0483-00 & P0483 with any other different last 2 digits in the DTC Are any of the cooling fan related DTCs listed, logged in the engine control module?
Yes
Please refer to section 100-00 and refer to the relevant DTC index and carry out repair procedure
Using the manufacturer approved diagnostic system clear all stored diagnostic trouble codes from the
diagnosis menu tab
Proceed to the test step A9 'Cooling fan validation procedure'
No
Proceed to the next step. A2 'Check for other DTCs' A2: CHECK FOR OTHER DTCS 1 Using the manufacturer approved diagnostic system check the engine control module for DTCs Are any other DTCs listed, logged in the engine control module?
Yes
Please refer to section 100-00 and refer to the relevant DTC index and carry out repair procedure

1 LH fuel rail 2 Crossover tube 3 RH fuel rail 4 FRP sensor 5 Fuel injector (8 off) The fuel rails and crossover tube are made from stainless steel. Bolts attach each fuel rail to the related cylinder head. The
crossover tube connects the front high pressure line to the LH fuel rail, which ensures there is equal pressure in the two fuel rails. Four P-clips attach the crossover tube to the intercooler-tank top.
The rear of the RH fuel rail incorporates a threaded boss for installation of the FRP sensor. FUEL RAILS AND CROSSOVER TUBE
RH fuel rail. The FRP sensor is screwed into a threaded boss in the fuel rail. A flying lead and three pin connector provides the interface with the engine harness.
The FRP sensor contains a steel diaphragm fitted with strain gages, which are incorporated into a Wheatstone bridge. The output from the Wheatstone bridge is processed by the ECM to derive a pressure value.
FUEL INJECTORS
The fuel injectors spray fuel from the fuel rail directly into the combustion chambers. The fuel injectors are installed close to
the center of the combustion chambers, between the inlet and exhaust valves and next to the spark plug.
The fuel injectors are a push fit in the fuel rails and the cylinder heads. On each fuel injector, a rubber O-ring seals the head of
the fuel injector in the fuel rail. A teflon ring seals the nozzle of the fuel injector in the cylinder head. A clamp locks each fuel
injector to the fuel rail. FUEL RAIL PRESSURE SENSOR

Principles of Operation
For a detailed description of the fuel charging and controls system and operation, refer to the relevant Description and
Operation section of the workshop manual. REFER to:
Fuel Charging and Controls (303-04D Fuel Charging and Controls - V8 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04D Fuel Charging and Controls - V8 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04D Fuel Charging and Controls - V8 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04E Fuel Charging and Controls - V8 S/C 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04E Fuel Charging and Controls - V8 S/C 5.0L Petrol, Description and Operation), Fuel Charging and Controls (303-04E Fuel Charging and Controls - V8 S/C 5.0L Petrol, 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.

Fuel level
Fuel leaks
Damaged fuel lines
Damaged push connect fittings
Fuel contamination/grade/quality
Throttle body

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.

and is correctly installed. Check for ignition system, fuel
system and electronic engine control DTCs and refer to the
relevant DTC Index Engine cranks and fires, but

Torque: 10 Nm
CAUTIONS:
Take extra care when removing the throttle body,
failure to follow this instruction may result in damage to
the manifold absolute pressure and temperature (MAPT)
sensor.
Do not attempt to clean the throttle body bore, build
up of deposits reduces air leakage past the throttle plate at
the fully closed position.
Remove and discard the gasket.
1. To install, reverse the removal procedure.
