id0140f1809700

  Note

  • Perform the following test only when directed.

## Visual Inspection

1. Inspect the boost sensor for damage and cracks.

  • If not as specified, replace the boost sensor.

2. Inspect vacuum hose for improper routing, kinks or leakage.

  • If there is any malfunction, repair or replace suspected hose.

## Voltage Inspection

1. Turn the engine switch to ON.

2. Monitor the MAP PID using the WDS or equivalent.

  • If not as specified, perform the "Circuit Open/Short Inspection".

  - If there is no open/short circuit, replace the boost sensor. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)])

MAP PID

  0.6-1.0 V

3. Start the engine and warm up the engine completely.

4. Monitor the MAP PID using the WDS or equivalent at idle.

  • If not as specified, perform the "Circuit Open/Short Inspection".

  - If there is no open/short circuit, replace the boost sensor. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)])

MAP PID

  0.6-1.0 V

## Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)])

2. Disconnect the boost sensor connector.

3. Inspect for open/short circuit in the following wiring harnesses.

  • If there is open/short circuit, repair or replace wiring harnesses.
