System Wiring Diagram
• Not applicable
Function Explanation (DTC Detection Outline)
• The PCM calculates the target fuel pressure appropriate to the engine conditions relative to the actual fuel pressure based on the fuel pressure signal, and provides feedback to the high pressure fuel pump control.
• If the average fuel pressure exceeds the specified value, the PCM determines a malfunction in the high pressure fuel pump system, and stores a DTC.
• If the fuel pressure decreases to the specification or less instantaneously after the fuel pressure on the high pressure side measured by the fuel pressure sensor exceeds the specification, the PCM determines a malfunction in the high pressure fuel pump system, and stores a DTC.
Repeatability Verification Procedure
1. Warm up the engine to allow the engine coolant temperature to reach 80 °C {176 °F} or more.
2. Start the engine and leave it idling for 1 min.

|
Repair completion verification 1
|
PURPOSE: VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory. (See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Is the same Pending DTC present?
|
Yes
|
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, replace the PCM, then go to the next step.
|
|
No
|
Go to the next step.
