A Camshaft Position Actuator Position Sensor A Circuit Low Bank 1

Where it lives

For P34AE, the sensor sits on the circuit this code reports. The description of P34AE puts it on bank 1.

Check these first

• A failing camshaft position actuator position sensor A on bank 1
• Corrosion or damage in the sensor A wiring or connector on bank 1
• A short to ground on the sensor A signal circuit
• A stuck or slow camshaft position actuator on bank 1
• Loss of reference voltage or ground at sensor A

What to do next

1. Check reference voltage and ground at camshaft position actuator sensor A on bank 1
2. Inspect the sensor A connector for oil or corrosion
3. Test the sensor A signal circuit for a short to ground
4. Read camshaft position actuator sensor A data with a scan tool
5. Replace camshaft position actuator position sensor A if the signal stays low
6. Clear the code and retest
