What P2261 means
P2261 means bypass valve A of the turbocharger or supercharger, also called the recirculation valve, does not work mechanically. When the throttle snaps shut it should let charge air flow back to the compressor inlet so the compressor does not surge. GM's 2018 tables look for a valve stuck closed in coast-down: with the valve commanded open and at least 1,200 rpm, a high-pass filtered airflow signal above 30 g/s or a filtered boost slope above 500 kPa/s reveals surge; 8 failures in 10 tests give a Type B fault. GM bulletin 16-NA-020 (2016 Encore/Malibu 1.4/1.5 L) blames a sticking valve, 23-NA-033 (2023 Equinox/Terrain) an ECM whose short-circuit detection reacted to back voltage, and Kia campaign SC230 (2022 Seltos 1.6 T-GDI) a kinked recirculation hose. A flutter or rattle on lift-off is typical.
P2261 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2261
- Fluttering, chuffing or rattling noise from the turbo when lifting off the throttle
- MIL on
- Slightly delayed boost after gear changes
Common causes of P2261
- Most likelyBypass/recirculation valve sticking closed or with a torn diaphragm
- PossibleKinked, collapsed or wrongly routed recirculation or control hose
- PossibleElectrical fault at the valve solenoid or its connector that prevents opening
- Less likelyEngine control module output reacting wrongly (software or hardware)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2261 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| 61 | The exact fault in that area. |
What to do next
- Note P2261 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 P2261
What does P2261 mean?
P2261 means "Turbocharger/Supercharger Bypass Valve A - Mechanical". P2261 means bypass valve A of the turbocharger or supercharger, also called the recirculation valve, does not work mechanically. It is a generic code, so it means the same on every make.
Is it safe to drive with P2261?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2261 fail an emissions test?
Yes, it can. P2261 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 P2261 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2261 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.
