Control Module Internal Temperature Sensor B Circuit High

Where it lives

For P06AE, the circuit described runs through the sensor. The description of P06AE reports a fault at the sensor.

Check these first

• An open internal temperature sensor B inside the control module
• A chafed or shorted wire in the sensor B circuit
• Corrosion or water in the sensor B connector
• A failed module driver reading the internal sensor
• Electrical noise on the sensor B circuit

What to do next

1. Read internal temperature sensor B live data on a scan tool
2. Check the sensor B wiring for opens and shorts
3. Inspect the sensor B connector for corrosion or water
4. Compare sensor B against sensor A or ambient temperature
5. Replace the control module if the internal sensor stays high
6. Clear the code and retest
