A/C Compressor Motor Voltage Sensor A Performance

Where it lives

For P0D69, the part to look at first is the sensor named here.

Check these first

• An A/C compressor motor voltage sensor A that has drifted out of range
• A failing compressor motor drawing voltage the sensor cannot track
• Reference or ground drift on the motor voltage sensor circuit
• A chafed motor voltage sensor wire

What to do next

1. Read the compressor motor voltage sensor on a scan tool under load
2. Compare the reading to a meter at the motor
3. Check the sensor reference and ground
4. Inspect the motor voltage sensor wiring for chafing
5. Replace the sensor or compressor if the reading stays out of range
6. Clear the code and retest
