P34AFA Camshaft Position Actuator Position Sensor A Circuit High Bank 1
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P34AF is logged when position sensor A on the bank 1 intake phaser reports a voltage above its upper limit for at least one second. Mitsubishi covers the code in its 2022 Outlander manual and, besides the harness, points to the Hall sensor of motor 1 in the electric actuator – a hint that position sensor A is a Hall element inside the phaser motor. A broken ground lead of the sensor, a signal line in contact with supply voltage or a dead Hall sensor are the usual causes; since the sensor is built into the actuator, a sensor fault normally means a new actuator. Fail-safe parks the intake phaser at its base angle, opens the intake runner valve and switches off exhaust gas recirculation. Low is P34AE, bank 2 P34B3.
- What you may notice
- Check engine light on
- Intake phaser held in its base position, reduced power
- Slightly higher fuel consumption
- Likely causes
- LikelySensor ground open or plug corroded
- PossibleSignal wire shorted to supply voltage
- PossibleHall sensor of the actuator motor failed (actuator replacement)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
