P34ACA Camshaft Position Actuator Position Sensor A Circuit 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
- P34AC covers any electrical fault in the circuit of position sensor A of the intake cam actuator on bank 1. On engines with an electric intake phaser this sensor tells the controller where the drive motor stands. Mitsubishi has the code in its 2022 Outlander manual: the electric intake valve timing module logs it when the sensor voltage is too low or too high for one second or longer, and names wiring with an open or short as well as the actuator itself. In fail-safe the phaser is parked at its base angle, the intake runner valve opens, EGR stops and the cold-start stratified mode is dropped. The check runs once the engine has been above 2,000 rpm for a second and first appears as a pending code. Low and high are P34AE and P34AF.
- What you may notice
- Check engine light on
- Intake cam held in its base position, less torque at low revs
- Rougher cold start, slightly higher consumption
- Likely causes
- LikelyActuator harness open or shorted, plug loose
- PossiblePosition sensor in the electric actuator failed (actuator replacement)
- RareElectric valve timing control module faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
