P2025 EVAP Fuel Vapor Temperature Sensor Performance
The EVAP fuel-vapor temperature sensor reading is plausible but does not match expected behaviour over time or temperature — slow response, incorrect offset, or stuck reading.
Is it safe to drive with P2025?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
