Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Temperature Sensor: Notes
Measure and record the resistance between the signal terminal 1 and the low reference circuit terminal 2 at the fuel temperature sensor. Compare the value to the Temperature vs. Resistance table. Refer to Temperature Versus Resistance (ECT Sensors) or Temperature Versus Resistance (EGR Temperature Sensors) or Temperature Versus Resistance (EGT Sensors) or Temperature Versus Resistance (Fuel Temperature Sensor) or Temperature Versus Resistance (IAT Sensor 1) or Temperature Versus Resistance (IAT Sensor 2) .
- If the sensor does not closely match through the temperature ranges, replace the fuel temperature sensor.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
