Circuit/System Verification
WARNING: This page is about a different variant/trim than selected.
- Ignition ON.
- Observe the DTC information with a scan tool. Verify no other DTCs are set.
- If other DTC is set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis.
- If other DTC is not set
- If other DTC is set
- Observe the Fuel Rail Pressure Sensor parameter with a scan tool. During engine cranking, the pressure should be greater than 10 MPa (1450 psi).
- If 10 MPa (1450 psi) or less
Refer to Circuit/System Testing.
- If greater than 10 MPa (1450 psi)
- If 10 MPa (1450 psi) or less
- Observe the Fuel Rail Pressure Sensor parameter with a scan tool, at idle the pressure should be close to the Desired Fuel Rail Pressure. As the engine speed increases, the Desired Fuel Rail Pressure and the Actual Fuel Rail Pressure should closely match each other.
- If pressure does not closely match
Refer to Circuit/System Testing.
- If pressure closely matches
- If pressure does not closely match
- Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
- Verify the DTC does not set.
- If the DTC sets
Refer to Circuit/System Testing.
- If the DTC does not set
- If the DTC sets
- All OK.
