What P0A35 means
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.
P0A35 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0A35
- Noticeable loss of electric drive power
- Hybrid system overheat or warning message
- Engine runs more often to compensate
Common causes of P0A35
- Most 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
- Less likelyExtended high load such as towing or long climbs
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0A35 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| A | Area: hybrid propulsion. |
| 35 | The exact fault in that area. |
What to do next
- Note P0A35 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0A35
What does P0A35 mean?
P0A35 means "Drive Motor B Over Temperature". Unlike the sensor codes, P0A35 reports that motor B is actually too hot according to a working sensor. It is a generic code, so it means the same on every make.
Is it safe to drive with P0A35?
Drive gently and only to a workshop. With P0A35 the car can go into limp mode (reduced power) to protect itself.
Will P0A35 fail an emissions test?
Yes, it can. P0A35 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0A35 to fix?
Difficulty: hard. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P0A35 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
