U012E Lost Communication With Camshaft Position Control Module

U012E applies to engines whose camshaft phaser is driven by its own electronic unit rather than an oil control solenoid, as with electric intake valve timing. Mitsubishi bulletin TSB-23-11-003 for the 2022 Outlander lists U012E next to U0101, U0122, U0146, U0155 and U042F as communication codes of the engine controller and links it in the warranty chart to the electric intake valve timing control module circuit. Without the module the engine controller cannot adjust intake timing, so power and exhaust quality suffer; the code counts as emissions relevant, and a MIL is to be expected, although no maker states it openly. U042F flags invalid data from the same unit; P0010 ff. cover the actuators themselves.

Likely causes

Power or ground of the electric valve timing module interrupted
CAN wiring or connector at the engine damaged by heat or oil
Camshaft position control module internally faulty

Symptoms

  • MIL on
  • Reduced power and poorer response, especially at low engine speed
  • Rough idle or higher fuel consumption
