What P0A97 means
P0A97 is the fan 2 counterpart of P0A82: the second battery cooling fan is electrically reachable but does not reach its requested speed or does not turn at all. No manufacturer documents this exact code publicly. CARB requires a functional check of battery cooling where feasible, and the methods are published for fan 1: GM compares commanded and measured speed (its sense code P0BC8), Toyota judges the deviation of the feedback-corrected duty, Honda compares expected and actual battery temperature rise. Blocked air paths and worn motors are the usual causes. Circuit faults on fan 2 are P0A96, P0A99 and P0A9A; the stuck-on case is P0A98. With one fan weak the pack runs warmer.
P0A97 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0A97
- Hybrid warning or check engine light
- Weak airflow from the battery vents
- Reduced electric assist in warm weather
Common causes of P0A97
- Most likelyDust or debris on fan 2 or in its duct
- PossibleWorn or seized fan 2 bearings
- PossibleBlocked air intake to the battery
- Less likelyFaulty speed feedback from fan 2
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0A97 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. |
| 97 | The exact fault in that area. |
What to do next
- Note P0A97 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 P0A97
What does P0A97 mean?
P0A97 means "Hybrid/EV Battery Pack Cooling Fan 2 Performance/Stuck Off". P0A97 is the fan 2 counterpart of P0A82: the second battery cooling fan is electrically reachable but does not reach its requested speed or does not turn at all. It is a generic code, so it means the same on every make.
Is it safe to drive with P0A97?
Drive gently and only to a workshop. With P0A97 the car can go into limp mode (reduced power) to protect itself.
Will P0A97 fail an emissions test?
Yes, it can. P0A97 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 P0A97 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3.5 hours of work. This is a job for a workshop.
Will P0A97 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.
