What P271E means
P271E is a broad performance code for the transmission as a whole, used when the controller finds that the gearbox does not deliver what it should even though no single sensor or valve has failed. Honda applies it to the CVT of the 2016-2020 HR-V: service bulletin A21-046 adds P271E with new PCM software that detects early slip of the primary drive belt. When it sets, the D indicator flashes, the MIL comes on and engine output is cut to protect the belt from breaking. Companion bulletin A21-047 extends CVT warranty to 7 years or 150,000 miles because the belt is now OBD-monitored, and the inspection uses a magnet to look for metal shed by the belt. Other makers may use P271E with other meanings, so the maker's own diagnosis decides what was measured.
P271E at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 12 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P271E
- Flashing D indicator and MIL on
- Reduced engine power
- Engine flare or weak acceleration
Common causes of P271E
- Most likelySlipping or deteriorating CVT drive belt (Honda HR-V)
- PossibleInsufficient clamping or line pressure in the transmission
- Less likelyControl software without the latest calibration
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P271E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 1E | The exact fault in that area. |
What to do next
- Note P271E 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 P271E
What does P271E mean?
P271E means "Transmission Performance". P271E is a broad performance code for the transmission as a whole, used when the controller finds that the gearbox does not deliver what it should even though no single sensor or valve has failed. It is a generic code, so it means the same on every make.
Is it safe to drive with P271E?
Drive gently and only to a workshop. With P271E the car can go into limp mode (reduced power) to protect itself.
Will P271E fail an emissions test?
Yes, it can. P271E 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 P271E to fix?
Difficulty: workshop only. A typical repair takes 1 to 12 hours of work. This is a job for a workshop.
Will P271E clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
