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".

Specification

Water temperature (°C {°F})

Resistance (kilohm)

20 {68}
2.21-2.69
80 {176}
0.29-0.35

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.

Open circuit

• Exhaust gas pressure correction temperature sensor terminal A and PCM terminal 58
• Exhaust gas pressure correction temperature sensor terminal B and PCM terminal 68

Short circuit

• Exhaust gas pressure correction temperature sensor terminal A and power supply
• Exhaust gas pressure correction temperature sensor terminal A and body ground
• Exhaust gas pressure correction temperature sensor terminal B and power supply
