FUEL PRESSURE SENSOR INSPECTION [L3 Turbo]

id0140b6801300

  Note

  • Perform the following inspection only when directed.
  • The following vacuum values are indicated by relative pressure from the fuel pressure sensor.

1. Remove the charge air cooler cover.

2. Connect the WDS or equivalent to the DLC-2.

3. Turn the ignition switch to the ON position (Engine off).

4. Select the FUEL_PRES PID on the WDS or equivalent.

5. After warming up the engine, verify that the FUEL_PRES PID is at the standard value under the following conditions.

  - If not as verified, replace the fuel delivery pipe.

Step | Condition | FUEL_PRES PID
--- | --- | ---
1 | • Idle • 90 s after engine is started | Approx. 3 MPa
2 | • Idle • Spill valve solenoid valve connector is disconnected | Approx. 530 kPa

6. After connecting the spill valve control solenoid valve connector, clear the DTC.

## Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)

2. Inspect the following wiring harnesses for an open or short circuit. (Continuity check)

### Open circuit

  • If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
  - Fuel pressure sensor terminal A and PCM terminal 2H
  - Fuel pressure sensor terminal B and PCM terminal 1V
  - Fuel pressure sensor terminal C and PCM terminal 2K

### Short circuit

  • If there is continuity, there is a short circuit. Repair or replace the wiring harness.
  - Fuel pressure sensor terminal A and power supply.
  - Fuel pressure sensor terminal B and power supply.
  - Fuel pressure sensor terminal B and body ground.
  - Fuel pressure sensor terminal C and body ground
