Crankcase Temperature Sensor Circuit Range/Performance

Where it lives

For P2EBC, the part to look at first is the sensor named here.

Check these first

• A crankcase temperature sensor reading outside its expected range
• A failed crankcase temperature sensor
• High resistance in the sensor circuit
• A corroded sensor connector
• A control module calibration fault

What to do next

1. Read crankcase temperature on a scan tool
2. Compare the reading to coolant temperature after a cold soak
3. Test the sensor circuit for added resistance
4. Inspect the sensor connector for corrosion
5. Replace the crankcase temperature sensor if the reading stays skewed
6. Clear the code and retest
