P34B2A Camshaft Position Actuator Position Sensor A Circuit Low 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
- P34B2 is set when position sensor A on the intake phaser of bank 2 delivers a voltage below its permitted window. Public manufacturer information on this code is lacking. On the 2022 Mitsubishi Outlander the bank 1 version P34AE is evaluated by the electric valve timing module and traced to the actuator circuit or the actuator. Mercedes calls the corresponding low code of its CAMTRONIC exhaust sensors on bank 2 (P34C2) a ground short and, in bulletin LI05.20-P-080192, has the engine harness by the bulkhead inspected for scorching. A grounded signal wire, a missing sensor supply or a shorted sensor are therefore the first things to rule out on bank 2. High is P34B3, bank 1 P34AE.
- What you may notice
- Check engine light on

- PossibleSensor supply interrupted
- PossibleSensor in the actuator shorted
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
