Exhaust Gas Recirculation Temperature (EGRT) Sensor - All Others

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2016 Ford Transit-350 HD, 2016 Ford Transit-350, 2016 Ford Transit-250, 2016 Ford Transit-150, and 2016 Ford F-550 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

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.
