Pinpoint Test HC: Fuel Delivery System
WARNING: This page is about a different variant/trim than selected.
WARNING:
Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.
WARNING:
Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING:
Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING:
When handling fuel, always observe fuel handling precautions and be prepared in the event of fuel spillage. Spilled fuel may be ignited by hot vehicle components or other ignition sources. Failure to follow these instructions may result in serious personal injury.
WARNING:
Clean all fuel residue from the engine compartment. If not removed, fuel residue may ignite when the engine is returned to operation. Failure to follow this instruction may result in serious personal injury.
WARNING:
Fuel may remain pressurized in some fuel lines after the Fuel System Pressure Release procedure. Wear safety gloves and a face shield when disconnecting pressure lines to avoid skin and eye contact. Failure to follow this instruction may result in serious personal injury.
NOTE:
Replacement fuel injectors may not be the same color as the original injectors in the vehicle. Verify the replacement injector is correct for the application by part number.
NOTE:
With the engine running, the FRP PID value may be higher than a fuel pressure reading taken with a mechanical gauge.
Normal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PCM P008A:00 | Low Pressure Fuel System Pressure - Too Low: No Sub Type Information | Sets when PCM detects the low pressure fuel system pressure falls below an expected threshold. |
| PCM P008B:00 | Low Pressure Fuel System Pressure - Too High: No Sub Type Information | Sets when PCM detects the low pressure fuel system pressure rises above an expected threshold. |
| PCM P00BA:00 | Low Fuel Pressure -Forced Limited Power: No Sub Type Information | Sets when PCM detects the fuel delivery volume is less than the requested fuel delivery volume and the PCM has reduced engine power as a result. |
| PCM P00BB:00 | Fuel Injector Insufficient Flow -Forced Limited Power: No Sub Type Information | Sets when PCM detects the requested fuel delivery volume is greater than the fuel injectors maximum delivery volume. A high fuel ethanol content combined with pulling or carrying a heavy load up a steep grade could set this DTC. A high fuel ethanol content combined with pulling or carrying a heavy load up a steep grade could set this DTC. |
| PCM P0148:00 | Fuel Delivery Error: No Sub Type Information | Sets when PCM detects at least one bank is lean at WOT. |
