P0A36 Generator Temperature Sensor Circuit

P0A36 is the general circuit code for the temperature sensor in the hybrid generator, the machine that is mainly driven by the engine to produce electricity. It covers faults the module detects on the sensor line without classing them as low, high or implausible. No manufacturer documents P0A36 publicly; Mitsubishi (2023 Outlander PHEV) monitors its generator coil sensor with the specific codes P0A37 to P0A39 instead. CARB 1968.2 requires circuit monitoring for hybrid components that can affect emissions. With the generator temperature unknown, the system cannot protect the windings, so it usually restricts generator output and series operation and shows a hybrid warning.

Likely causes

Loose or corroded connector between generator and its control unit
Damaged sensor wiring near the transaxle
Generator coil thermistor failed (usually replaced with the generator)
Faulty input in the generator control unit

Symptoms

  • Hybrid warning or check engine light
  • Generator output or battery charging restricted
  • Generator temperature missing or implausible in live data
