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.
Exhaust Gas Recirculation Temperature (EGRT) Sensor - All Others
The EGRT sensor is a thermistor type sensor. The electrical resistance of the sensor increases as the temperature decreases, and the resistance decreases as the temperature increases. The varying resistance changes the voltage drop across the sensor terminals and provides electrical voltage to the PCM corresponding to temperature. The EGRT sensor is an input to the PCM.
The EGRT sensor is used to determine if the EGR cooler is operating correctly.
For F-Series Super Duty wide frame vehicles, the EGRT bank 1, sensor 1 (EGRT11) monitors the exhaust gas temperature before the EGR cooler and the EGRT bank 1, sensor 2 (EGRT12) monitors the exhaust gas temperature after the EGR cooler.
For all others, the EGRT12 sensor monitors the exhaust gas temperature after the EGR cooler.

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.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • 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.
