Control Module Internal Temperature Sensor A Circuit Intermittent/Erratic

Where it lives

For P267F, the sensor sits on the circuit this code reports. The description of P267F reports a fault at the sensor.

Check these first

• An intermittent open in the control module internal temperature sensor A circuit
• A failing control module internal temperature sensor A
• A loose or corroded connector at the control module internal temperature sensor A
• High resistance in the control module internal temperature sensor A wiring

What to do next

1. Read control module internal temperature sensor A on a scan tool
2. Wiggle test the control module internal temperature sensor A harness
3. Test the control module internal temperature sensor A circuit for intermittent opens
4. Check the control module internal temperature sensor A connector pins
5. Replace the control module if the internal circuit tests faulty
6. Clear the code and retest
