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

STEP

INSPECTION

RESULTS

ACTION

INSPECTION

RESULTS

ACTION

1

• Replace the following parts.

• High pressure fuel pump

  (See HIGH PRESSURE FUEL PUMP REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

• High pressure fuel pipe

  (See HIGH PRESSURE FUEL PUMP REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

• Fuel injector No.1

  (See FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

• Fuel injector No.2

• Fuel injector No.3

• Fuel injector No.4

• Fuel distributor

  (See FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

—

Go to the next step.

2

• Always reconnect all disconnected connectors.

• Clear the DTC from the PCM memory using the M-MDS.

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

• Perform the KOER self test.

  (See KOEO/KOER SELF TEST [PCM (SKYACTIV-G 2.0)].)

• Is the same DTC present?

Yes

Replace the PCM, then go to the next step.

(See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

No

Go to the next step.

3

• Is any other DTC or pending code stored?

Yes

Go to the applicable DTC inspection.

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

No

DTC troubleshooting completed.
