EXHAUST GAS PRESSURE CORRECTION TEMPERATURE SENSOR INSPECTION [MZR-CD (RF Turbo)]

id0140f1446200

Note
•  Perform the following test only when directed.

Resistance Inspection

1.  Remove the exhaust gas pressure correction temperature sensor. (See EXHAUST GAS PRESSURE SENSOR/EXHAUST GAS PRESSURE CORRECTION TEMPERATURE SENSOR REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)

2.  Place the exhaust gas pressure correction temperature sensor in water with a thermometer, and heat the water gradually.

3.  Measure the resistance between the exhaust gas pressure correction temperature sensor terminals using an ohmmeter.

•  If not as specified, replace the exhaust gas pressure correction temperature sensor.
•  If exhaust gas pressure correction temperature sensor is okay, perform the “Circuit Open/Short Inspection”.

Circuit Open/Short Inspection

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

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

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