FUEL PRESSURE SENSOR INSPECTION [L3 Turbo]

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.

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
