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: 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
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

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.

INSPECTION

RESULTS

ACTION

1
PURPOSE: VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service 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 (MODE 2)
•  Is the DTC P0089:00 on FREEZE FRAME DATA (Mode 2)?
Yes
Go to the next step.
No
Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA (Mode 2).
3
PURPOSE: RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
•  Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
Note
•  Recording can be facilitated using the screen capture function of the PC.
4
PURPOSE: VERIFY RELATED PENDING CODE AND/OR DTC
•  Switch the ignition off, then ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Are any other PENDING CODEs and/or DTCs present?
Yes
Go to the applicable PENDING CODE or DTC inspection.
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.

INSPECTION

RESULTS

ACTION

1
PURPOSE: REPLACE HIGH PRESSURE FUEL SYSTEM RELATED PARTS DUE TO MALFUNCTION IN HIGH PRESSURE FUEL SYSTEM PARTS
•  Replace the following parts.
―  Fuel injector No.2
―  Fuel injector No.3
―  Fuel injector No.4
Go to the next step.
2
PURPOSE: VERIFICATION OF VEHICLE REPAIR COMPLETION
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
3
PURPOSE: VERIFY IF THERE IS ANY OTHER MALFUNCTION
•  Is any other DTC or pending code stored?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
