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: With the engine running, the FRP PID value may be 48-70 kPa (7-10 psi) 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 P0087:00 | Fuel Rail/System Pressure - Too Low (Bank 1): No Sub Type Information | Sets when the PCM detects the fuel rail pressure requested by the PCM is greater than the fuel rail pressure delivered, by more than a calibrated threshold for greater than a calibrated length of time. |
| PCM P0088:00 | Fuel Rail/System Pressure - Too High (Bank 1): No Sub Type Information | Sets when the PCM detects the fuel rail pressure requested by the PCM is less than the fuel rail pressure delivered, by more than a calibrated threshold for greater than a calibrated length of time. |
| PCM P0181:00 | Fuel Temperature Sensor "A" Circuit Range/Performance: No Sub Type Information | Sets when the PCM detects the fuel rail pressure temperature sensor is out of self-test range. Check for other PCM Diagnostic Trouble Codes (DTCs). Diagnose all other PCM Diagnostic Trouble Codes (DTCs) before continuing diagnosis. Bring the engine to normal operating temperature. Verify the engine coolant temperature is greater than 77°C (170°F) and the fuel rail temperature is greater than 10°C (50°F). Clear the PCM DTCs. Repeat the self-test. |
| PCM P0182:00 | Fuel Temperature Sensor "A" Circuit Low: No Sub Type Information | Sets when the PCM detects the fuel rail temperature sensor circuit is open or shorted to ground. |
| PCM P0183:00 | Fuel Temperature Sensor "A" Circuit High: No Sub Type Information | Sets when the PCM detects the fuel rail temperature sensor circuit is open or shorted to voltage. |
| PCM P018B:00 | Fuel Pressure Sensor "B" Circuit Range/Performance: No Sub Type Information | Sets when the PCM detects the voltage is outside a calibrated limit for a calibrated amount of time during testing. |
| PCM P018C:00 | Fuel Pressure Sensor "B" Circuit Low: No Sub Type Information | Sets when the PCM detects the fuel pressure sensor circuit is shorted to signal return or ground. A fuel pressure sensor PID value during ignition ON, engine OFF, or ignition ON, engine running, less than 0.3 volt indicates a concern is present. |
| PCM P018D:00 | Fuel Pressure Sensor "B" Circuit High: No Sub Type Information | Sets when the PCM detects the fuel pressure sensor circuit is open or shorted to voltage. |
| PCM P0192:00 | Fuel Rail Pressure Sensor Circuit Low (Bank 1): No Sub Type Information | Sets when the PCM detects the FRP circuit is shorted to SIGRTN or ground. A FRP sensor PID value during ignition ON, engine OFF, or ignition ON, engine running, less than 0.3 volt indicates a concern is present. |
| PCM P0193:00 | Fuel Rail Pressure Sensor Circuit High (Bank 1): No Sub Type Information | Sets when the PCM detects the FRP circuit is open or shorted to voltage. |

Children and Airbags
WARNING: Airbags can kill or injure a child in a child restraint. Never place a rear-facing child restraint in front of an active airbag. If you must use a forward-facing child restraint in the front seat, move the seat upon which the child restraint is installed all the way back.
