A/C Evaporator Temperature Sensor Circuit Range/Performance

Where it lives

For P0536, the part to look at first is the sensor named here.

Check these first

• An evaporator temperature sensor out of range
• A corroded sensor connector
• A short or open in the sensor circuit
• An incorrectly installed sensor
• A low refrigerant charge

What to do next

1. Read evaporator temperature data on a scan tool
2. Move the sensor harness and watch for jumps
3. Check the sensor circuit for opens or shorts
4. Verify the sensor is seated correctly
5. Replace the sensor if readings fall out of range
6. Clear the code and retest
