DTC P0089:00 [PCM (SKYACTIV-G 2.0)]

NOTE:

  • To determine the malfunctioning part, proceed with the diagnostics from “Function Inspection Using M-MDS”.

Details On DTCs

DESCRIPTION

Spill valve control solenoid valve control circuit range/performance problem

DETECTION CONDITION

Determination conditions

  • The average fuel pressure on the high pressure side, measured by the fuel pressure sensor, exceeds the specified value.

Preconditions

  • Engine speed: 500 rpm or more*1

  • The following DTCs are not detected:

    • Fuel pressure sensor: P0087:00, P0088:00, P0192:00, P0193:00

    • High pressure fuel pump: P0091:00, P0092:00

  • *1: Value can be verified by displaying PIDs using M-MDS

Malfunction determination period

  • 2 s period

Drive cycle

  • 1

Self test type

  • CMDTC self test, KOER self test

Sensor used

  • Fuel pressure sensor

FAIL-SAFE FUNCTION

  • Limits intake air amount

  • Stops high pressure fuel pump control.

  • The upper limit of the engine speed is 2,500 rpm.

VEHICLE STATUS WHEN DTCs ARE OUTPUT

  • Illuminates check engine light.

POSSIBLE CAUSE

  • High pressure fuel pump connector or terminals malfunction

  • PCM connector or terminals malfunction

  • Fuel pressure sensor malfunction

  • High pressure fuel pump malfunction

    • Spill valve control solenoid valve (built-into high pressure fuel pump) malfunction

  • High pressure fuel pipe clogging

  • Fuel distributor malfunction

  • Fuel injector malfunction

  • PCM malfunction

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.

Repeatability Verification Procedure

  • Warm up the engine to allow the engine coolant temperature to reach 80 °C {176 °F} or more.

  • Start the engine and leave it idling for 1 min.

PID Item/Simulation Item Used In Diagnosis

  • Not applicable

Function Inspection Using M-MDS

STEP

INSPECTION

RESULTS

ACTION

1

 PURPOSE: VERIFY RELATED REPAIR INFORMATION AVAILABILITY

  • Verify related Service Bulletins and/or on-line repair information availability.

  • Is any related repair information available?

Yes

Perform repair or diagnosis according to the available repair information.

  • If the vehicle is not repaired, go to the next step.

No

Go to the next step.

2

 PURPOSE: IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA

  • Is the DTC P0089:00 on FREEZE FRAME DATA?

Yes

Go to the next step.

No

Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA.

(See DTC TABLE [PCM (SKYACTIV-G 2.0)].)

3

 PURPOSE: RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION

NOTE:

  • Recording can be facilitated using the screen capture function of the PC.

  • Record the FREEZE FRAME DATA/snapshot data on the repair order.

Go to the next step.

4

 PURPOSE: VERIFY RELATED PENDING CODE AND/OR DTC

Yes

Go to the applicable PENDING CODE or DTC inspection.

(See DTC TABLE [PCM (SKYACTIV-G 2.0)].)

Go to the troubleshooting procedure to perform the procedure from Step 1.

No

Go to the troubleshooting procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

    Intention of troubleshooting procedure

  • Step 1

    • Replace the high pressure fuel system parts.

  • Step 2—3

    • Verify that the primary malfunction is resolved and there are no other malfunctions.
