EVAP Fuel Vapor Temperature Sensor Circuit Low Voltage

Where it lives

For P2026, the circuit described runs through the sensor. The description of P2026 reports low voltage at the sensor.

Check these first

• A short to ground on the fuel vapor temperature sensor signal wire
• An open in the sensor circuit
• A failed fuel vapor temperature sensor
• Low battery voltage affecting the sensor reference

What to do next

1. Read EVAP fuel vapor temperature sensor voltage on a scan tool
2. Test the sensor signal wire for a short to ground
3. Check the sensor connector and pins
4. Verify reference voltage at the sensor
5. Replace the fuel vapor temperature sensor if the circuit tests good
6. Clear the code and retest
