A Camshaft Position Actuator Temperature Sensor Circuit Bank 2

Where it lives

For P34A8, the circuit described runs through the sensor. The description of P34A8 puts it on bank 2.

Check these first

• A bank 2 actuator temperature sensor contaminated by oil or coolant
• A worn sensing element inside the bank 2 temperature sensor
• A bank 2 sensor signal that drifts or reads erratically
• A loose or corroded connector at the bank 2 actuator temperature sensor

What to do next

1. Read the bank 2 actuator temperature sensor value on a scan tool
2. Compare the bank 2 sensor reading to a cold engine baseline
3. Inspect the bank 2 sensor connector for corrosion and moisture
4. Check the bank 2 sensor wiring for open and short faults
5. Replace the bank 2 actuator temperature sensor if the signal is erratic
6. Clear the code and retest
