What P2A60 means
P2A60 flags a tank B level that is electrically valid but does not behave like a real fuel quantity: it fails to drop while gas is used from tank B, does not climb after filling, or swings wildly although the tank is at rest. Roush documents the stuck logic for its propane primary sender as P25B0, set when the value stays put over a considerable distance. On LPG the cause is often mechanical, a float arm bent or jammed inside the tank; with CNG, where the level is calculated, a drifting pressure sensor or a cold fill can mislead it, and GM notes that its gauge may read below full after refuelling in the cold. No manufacturer publishes P2A60 or its limits; CARB asks for rationality checks on such inputs. Compare the sender with the tank's own dial gauge.
P2A60 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P2A60
- Check engine light after several trips
- Gas gauge does not move as fuel is used
- Unexpected running out of gas
Common causes of P2A60
- Most likelyFloat arm in tank B bent or jammed (LPG)
- PossiblePressure or temperature input behind the calculated level drifting (CNG)
- Less likelyContact resistance shifting the sender signal
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2A60 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| A | Area: hybrid propulsion. |
| 60 | The exact fault in that area. |
What to do next
- Note P2A60 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 P2A60
What does P2A60 mean?
P2A60 means "Alternative Fuel Tank B Level Sensor Range/Performance". P2A60 flags a tank B level that is electrically valid but does not behave like a real fuel quantity: it fails to drop while gas is used from tank B, does not climb after filling, or swings wildly although the tank is at rest. It is a generic code, so it means the same on every make.
Is it safe to drive with P2A60?
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 P2A60 fail an emissions test?
Yes, it can. P2A60 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 P2A60 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2A60 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.
