Evaporative Emissions (EVAP) Fuel Vapor Temperature Sensor Performance

DTC P2025, sometimes indicated as P202500 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing evaporative emissions (evap) fuel vapor temperature sensor performance.

The evaporative emissions control system (EVAP) monitors the fuel vapor in the vehicle's fuel tank. The EVAP system prevents gasoline vapors from escaping into the atmosphere. The EVAP system has a fuel vapor temperature sensor that monitors the temperature of the fuel vapor.
The DTC P2025 is set when the fuel vapor temperature sensor is not performing as expected. There are several possible causes for this DTC.
One possible cause is a defective fuel vapor temperature sensor. Another possible cause is a leak in the EVAP system. A leak in the EVAP system can allow fuel vapors to escape into the atmosphere.
The most common solution for the DTC P2025 is to replace the fuel vapor temperature sensor. If there is a leak in the EVAP system, it must be repaired.
