The P2027 trouble code indicates a high voltage condition detected in the evaporative emissions (EVAP) fuel vapor temperature sensor circuit.
P2027 Evaporative Emissions (EVAP) Fuel Vapor Temperature Sensor Circuit High Voltage
Code symptoms P2027.
1. Check Engine Light (CEL) illuminated.
2. Fuel odor from the vehicle.
3. Irregular fuel gauge readings.
4. Decreased fuel efficiency.
This code is common in brands such as:: Chevrolet, Renault, Ford, Toyota, Nissan, Mercedes Benz, Honda.
Causes of the code P2027.
1. Faulty evaporative emissions (EVAP) fuel vapor temperature sensor.
2. Wiring or connector issues in the EVAP fuel vapor temperature sensor circuit.
3. Corrosion or damage in the EVAP system components.
4. High voltage supply to the EVAP fuel vapor temperature sensor circuit.
Code Solutions P2027.
1. Test the evaporative emissions (EVAP) fuel vapor temperature sensor for proper functionality. Replace if necessary.
2. Inspect the wiring and connectors in the EVAP fuel vapor temperature sensor circuit for any damage, corrosion, or loose connections. Repair or replace as needed.
3. Check the EVAP system components, such as the canister, purge valve, and vent valve, for any signs of malfunction. Repair or replace as necessary.
4. Ensure proper voltage supply to the EVAP fuel vapor temperature sensor circuit. Repair any issues with high voltage supply.
