B Camshaft Position Actuator Temperature Sensor Range/Performance Bank 2

Where it lives

For P34B9, start at the sensor the description names. The description of P34B9 puts it on bank 2.

Check these first

• A bank 2 B sensor reading outside its expected range
• A contaminated or slow responding bank 2 B sensing element
• A bank 2 B sensor that disagrees with bank 1
• A corroded connector skewing the bank 2 B signal

What to do next

1. Read the bank 2 B actuator temperature sensor value on a scan tool
2. Compare the bank 2 B reading to bank 1 on a cold and warm engine
3. Inspect the bank 2 B sensor for oil or coolant contamination
4. Check the bank 2 B sensor connector and wiring for faults
5. Replace the bank 2 B actuator temperature sensor if the range stays off
6. Clear the code and retest
