P34B0A Camshaft Position Actuator Position Sensor A Circuit Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P34B0 concerns the electrical circuit of position sensor A of the intake cam actuator on bank 2, so it only concerns V and boxer engines. No manufacturer publishes it. Mitsubishi documents the bank 1 code P34AC for the 2022 Outlander, which uses only the bank 1 codes: there the sensor reports the angle of the electric phaser motor, and a voltage outside its window for a second sets the fault. A two-bank engine with electric phasers would watch its second actuator in the same way. Mercedes, by contrast, files the sensors of its CAMTRONIC lift actuators under the position sensor A codes of camshaft B (P34BD, P34BE), so what the actuator is depends on the maker. Check plug, harness and actuator on bank 2.
- What you may notice
- Check engine light on
- Bank 2 intake phasing held in its base position
- Possibly less power and uneven running between banks
- Likely causes
- LikelyPlug or harness to the bank 2 actuator open or shorted
- PossiblePosition sensor in the actuator failed
- RareControl module fault
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
