The P2028 trouble code indicates an intermittent signal detected in the evaporative emissions (EVAP) fuel vapor temperature sensor circuit.
P2028 Evaporative Emissions (EVAP) Fuel Vapor Temperature Sensor Circuit Intermittent
Code symptoms P2028.
1. Check Engine Light (CEL) illuminated intermittently.
2. Fuel odor from the vehicle intermittently.
3. Irregular fuel gauge readings intermittently.
4. Intermittent decrease in fuel efficiency.
This code is common in brands such as:: Chevrolet, Renault, Ford, Toyota, Nissan, Mercedes Benz, Honda.
Causes of the code P2028.
1. Intermittent connection issues in the evaporative emissions (EVAP) fuel vapor temperature sensor circuit.
2. Intermittent fault in the EVAP fuel vapor temperature sensor.
3. Corrosion or damage in the EVAP system components.
4. Intermittent voltage supply issues to the EVAP fuel vapor temperature sensor circuit.
Code Solutions P2028.
1. Inspect the wiring and connectors in the EVAP fuel vapor temperature sensor circuit for intermittent damage, corrosion, or loose connections. Repair or replace as needed.
2. Test the evaporative emissions (EVAP) fuel vapor temperature sensor for intermittent functionality. Replace if necessary.
3. Check the EVAP system components, such as the canister, purge valve, and vent valve, for any signs of intermittent malfunction. Repair or replace as necessary.
4. Ensure consistent voltage supply to the EVAP fuel vapor temperature sensor circuit. Address any intermittent voltage supply issues.
