P0C69 is the general fault entry for the second pickup winding of the generator resolver. A resolver needs both windings, set 90 degrees apart, to give an unambiguous rotor angle; with only one, the inverter can no longer place the current in the generator phases correctly. The code applies when circuit B is judged faulty but not classified further. No manufacturer documents P0C69 publicly. At Mitsubishi on the 2023 Outlander PHEV circuit B corresponds to the cosine winding, and that design reports it only through the low and high codes P0C6B and P0C6C. CARB's hybrid rules require the generator to be monitored under an approved plan and circuit faults of input components to be detected. P0C64 is the same entry for circuit A.

Likely causes

Open or damaged lead in the second resolver pickup winding circuit
Bent, corroded or pushed-back pins at the resolver connector
Faulty second pickup winding in the resolver stator
Internal fault in the generator control electronics

Symptoms

  • Hybrid warning or malfunction indicator lamp
  • Generator switched off, battery is no longer recharged by the engine
  • Limited driving power
