BOOST SENSOR INSPECTION [MZR-CD (RF Turbo)]

BME014018212W02

  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".

MAP PID

  2.1-2.5 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".

MAP PID

  2.1-2.5 V

## Circuit Open/Short Inspection

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

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

### Open circuit
