The Diesel Exhaust Temperature Sensors (2) are thermistors and change resistance based on the temperature being measured. The Powertrain Control Module (PCM) provides a 5 volt reference voltage to the sensor. The PCM monitors the change in signal voltage and converts this to a temperature value.
For 2013 there are five exhaust temperature sensors:
- Exhaust Temperature Sensor (T1) is located in the front exhaust pipe.
- Exhaust Temperature Sensor (T2) is located in rear of the Diesel Oxygen Catalyst (DOC).
- Exhaust Temperature Sensor (T3) is located at the rear of Diesel Particulate Filter (DPF).
- Exhaust Temperature Sensor (T4) is located in the center of the Selective Reduction Catalyst (SCR) near the ammonia sensor.
- Exhaust Temperature Sensor (T5) is located at rear of the SCR.
