A Camshaft Position Actuator Position Sensor A Circuit High Bank 1

Where it lives

For P34AF, the circuit described runs through the sensor. The description of P34AF puts it on bank 1.

Check these first

• A short to voltage on the bank 1 actuator position sensor A signal circuit
• An open in the bank 1 position sensor A ground
• A failed bank 1 actuator position sensor A
• A corroded connector at the bank 1 position sensor A

What to do next

1. Read the bank 1 actuator position sensor A value on a scan tool
2. Test the bank 1 position sensor A circuit for a short to voltage
3. Check the bank 1 position sensor A ground for an open
4. Compare the bank 1 sensor A reading to the commanded actuator angle
5. Replace the bank 1 actuator position sensor A if the circuit tests good
6. Clear the code and retest
