P2411Fuel Cap Sensor/Switch Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2411 is stored when the fuel cap sensor or switch circuit reads above its normal window. With a pulled-up signal line this is what an open circuit, an unplugged connector or a short to the battery feed looks like, so it is often the code that follows a bodywork job or a filler-neck replacement. No manufacturer publicly documents P2411 or a threshold for it. The function is known from pressure-based cap monitoring: Ford's OBD summary sets P0457 after refuelling if tank vacuum stays above -8 inH2O for 30 s and uses a dedicated Check Fuel Cap lamp. CARB allows a separate indicator instead of the MIL for a detected cap leak, but circuit faults of the sensor remain normal input-component faults. P2410 is the low counterpart, P2412 the intermittent case.
- What you may notice
- Check engine light
- Cap warning behaves as if the cap were permanently open
- Likely causes
- LikelyOpen signal wire or unplugged connector, e.g. after body or filler-neck work
- PossibleSignal wire shorted to battery voltage
- PossibleSensor or switch failed open
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €20 – €200
