OBD-II Generic Error Code P2027: How to Fix It

Q: What causes OBD-II code P2027?

Code P2027 is typically caused by a faulty EVAP fuel vapor temperature sensor, damaged wiring, or a short circuit in the sensor circuit.

Q: Can I drive with a P2027 code?

Driving with this code is generally safe in the short term, but it can affect fuel economy and emissions. It's best to diagnose and fix it promptly.

Q: How do I clear code P2027?

After repairing the issue, use an OBD2 scanner to clear the code. Alternatively, disconnecting the battery for 10 minutes may also clear it, but the underlying fault must be fixed or the code will return.

Q: Where is the EVAP fuel vapor temperature sensor located?

It is usually located on the EVAP canister, the fuel tank, or the fuel vapor line. Check your vehicle's service manual for the exact location.

Q: Is P2027 the same as P2026?

No. P2026 refers to the EVAP fuel vapor temperature sensor range/performance, while P2027 indicates a high input (voltage too high).

Abstract

Error code P2027 indicates that the Engine Control Module (ECM) has detected a voltage signal from the EVAP fuel vapor temperature sensor that is higher than the expected range. This often points to a faulty sensor, wiring issues, or a short circuit. Our guide walks you through diagnosing and fixing this issue safely.
