U042FInvalid Data Received From Camshaft Position Control Module

- How the car detects it
- U042F concerns a camshaft position control module, used where an electric motor with its own electronics moves the phaser instead of an oil valve. The engine controller commands a target angle and receives actual position and status; U042F means those replies arrive but fail plausibility or protection checks, while U012E is set when they stop. For the 2022 Outlander, Mitsubishi's TSB-23-11-003 lists U042F beside U012E, U0101, U0122, U0146 and U0155 among the engine controller's network codes, and its parts list for that engine includes an electric intake valve timing control module. No maker documents more. CARB requires variable valve timing to be monitored for target errors and slow response. Without trusted feedback the controller holds intake timing at a default; expect a MIL, less power and higher emissions.
