P34AD covers a plausibility fault: the position sensor A signal from the intake actuator on bank 1 is electrically present but does not agree with what else the module knows. On the 2022 Mitsubishi Outlander, which turns its intake phaser electrically, the control module checks the motor position against the phase seen by the intake camshaft sensor and logs P34AD when the two disagree; wiring faults and the actuator are given as causes. In practice a worn or slipping actuator, a position that was not relearned after repairs or a disturbed cam signal come first; Nissan, which uses the same kind of electric intake valve timing, requires a position learning run after module replacement. The phaser then stays at its base angle.

Likely causes

Electric actuator worn, sticking or slipping
Actuator position not relearned after repair
Intake camshaft sensor signal or timing drive disturbed
Intermittent wiring fault

Symptoms

  • Check engine light on
  • Intake cam timing fixed, weaker response at low revs
  • Possibly accompanying timing codes such as P0011
