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

3.  Select the FUEL_PRES PID on the M-MDS.

4.  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

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

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 2P

―  Fuel pressure sensor terminal B and PCM terminal 2R

―  Fuel pressure sensor terminal C and PCM terminal 2I

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
