PID Inspection

Note

• Do not remove the fuel pressure sensor.

• If the fuel pressure sensor is removed, do not reuse the fuel pressure sensor and the fuel delivery pipe. When you replace the fuel pressure sensor, replace a new fuel delivery pipe with a new fuel pressure sensor.

1. Connect the M-MDS to the DLC-2.

2. Switch the ignition to ON.

3. Warm up the engine to normal operating temperature.

4. Access the FUEL_PRES PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZR 2.0 DISI i-stop].)

5. Verify that the FUEL_PRES PID is at the standard value under the following conditions.

Step

Condition

FUEL_PRES PID

1

•  Idle

•  90 s after engine is started.

Approx. 3 MPa

2

•  Idle

•  Spill valve control solenoid valve connector is disconnected.

Approx. 530 kPa

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

― If not as verified, replace the fuel delivery pipe. (See FUEL INJECTOR REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].)

6. Reconnect the spill valve control solenoid valve connector.

7. Clear the DTC using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [MZR 2.0 DISI i-stop].)
