What P0A2F means
Unlike its siblings, P0A2F reports a real thermal problem: the sensor works, but motor A stays too hot. GM sets it on 2013 two-mode trucks when the temperature exceeds 200 °C and does not fall below the 135 °C reset level, Type B, provided no circuit or plausibility fault is active. The 2011 table uses 159 °C; on the 2013 MGU mild hybrid the limit is 165 °C, and torque is already cut linearly from 100 % to zero between 155 and 165 °C. Hyundai lists the code in its Sonata Hybrid sensor bulletin, so a skewed sensor can mimic it. McLaren handles over-temperature under P0A2B98 and points to the dielectric cooling circuit. Expect a warning and sharply reduced electric power.
P0A2F 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 P0A2F
- Hybrid system or check engine warning
- Electric drive power drops sharply or is cut
- Engine runs more often to support the drive
Common causes of P0A2F
- Most likelyMotor cooling failure such as a weak pump, low fluid or blocked cooler
- PossibleSustained high load such as towing or long climbs in electric mode
- Less likelyTemperature sensor reading too high while still within range
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0A2F 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. |
| 2F | The exact fault in that area. |
What to do next
- Note P0A2F 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 P0A2F
What does P0A2F mean?
P0A2F means "Drive Motor A Over Temperature". Unlike its siblings, P0A2F reports a real thermal problem: the sensor works, but motor A stays too hot. It is a generic code, so it means the same on every make.
Is it safe to drive with P0A2F?
Drive gently and only to a workshop. With P0A2F the car can go into limp mode (reduced power) to protect itself.
Will P0A2F fail an emissions test?
Yes, it can. P0A2F 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 P0A2F to fix?
Difficulty: hard. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P0A2F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
