What P0A82 means
This code covers a fan 1 that is electrically intact but does not deliver the requested cooling, up to standing still. No manufacturer publishes code-exact criteria; CARB requires a functional check of battery cooling where feasible. Typical methods: GM compares commanded and fed-back fan speed (filed under its own sense code P0BC8), Toyota flags a fan whose feedback-corrected duty deviates too far from the expected value, and Honda compares expected and measured battery temperature rise. Causes are mostly mechanical: dust on the blades, a clogged intake filter, worn bearings. Circuit faults use P0A81/P0A84/P0A85; the stuck-on case is P0A83. The pack runs hotter and power may be limited.
P0A82 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P0A82
- Hybrid warning or check engine light
- Fan audibly weak or silent under load
- Reduced electric assist in warm weather
Common causes of P0A82
- Most likelyDust or debris on fan blades or in the duct
- Most likelyClogged or covered battery air intake or filter
- PossibleWorn or seized fan motor bearings
- Less likelyFaulty fan speed feedback signal
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0A82 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. |
| 82 | The exact fault in that area. |
What to do next
- Note P0A82 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 P0A82
What does P0A82 mean?
P0A82 means "Hybrid/EV Battery Pack Cooling Fan 1 Performance/Stuck Off". This code covers a fan 1 that is electrically intact but does not deliver the requested cooling, up to standing still. It is a generic code, so it means the same on every make.
Is it safe to drive with P0A82?
Drive gently and only to a workshop. With P0A82 the car can go into limp mode (reduced power) to protect itself.
Will P0A82 fail an emissions test?
Yes, it can. P0A82 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 P0A82 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0A82 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
