P0A35Drive Motor B Over Temperature

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
Unlike the sensor codes, P0A35 reports that motor B is actually too hot according to a working sensor. GM's 2011 hybrid tables set it above 149 °C (Type A, one trip); the 2013 two-mode trucks use 200 °C, clear it only below 135 °C and run it only while P0A31 is not active (Type B). Mitsubishi sets it on the rear motor of the 2023 Outlander PHEV when the coil reaches 177 °C for one second and names the motor assembly, electric water pump, EV cooling circuit and radiator fan as suspects. Sustained heavy load, towing or a cooling fault are the usual triggers. P0A2F is the same check for motor A, P0A3D for the motor B inverter. The system cuts motor B torque until it has cooled down.
What you may notice
  • Noticeable loss of electric drive power
  • Hybrid system overheat or warning message
  • Engine runs more often to compensate
Likely causes
  • LikelyElectric coolant pump of the drive cooling circuit failed or weak
  • PossibleLow coolant or transmission fluid in the motor cooling path
  • PossibleRadiator fan not running or radiator blocked
  • RareExtended high load such as towing or long climbs
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
