P34AE says the voltage from position sensor A on the bank 1 intake side remains under its minimum. The 2022 Mitsubishi Outlander, whose intake cam is moved by an electric motor, evaluates the code in the electric valve timing module and points to an open or shorted actuator circuit or a faulty actuator; unlike the circuit and high codes, no delay time is stated. Typical findings are a signal line touching ground, a missing sensor supply or a shorted Hall element in the motor. The module then stops phasing and keeps the intake cam at its base angle, which costs low-end torque; because the stratified cold start is also dropped, starts from cold may run rougher. P34AF is the high code, P34B2 the bank 2 code.

Likely causes

Signal line shorted to ground
Sensor supply open or shorted
Hall sensor in the actuator motor shorted (actuator replacement)

Symptoms

  • Check engine light on
  • Less pulling power at low revs
  • Rougher running after a cold start
