The reductant dosing module is controlled by the PCM. The reductant dosing module injects reductant into the exhaust system to reduce NOx coming out of…
The reductant tank stores the reductant or DEF. Under normal use it needs to be refilled at the same interval as the oil change.
Reductant, also known as Diesel Exhaust Fluid (DEF) is 32.5% urea/ water solution. When injected into the exhaust, there is a chemical reaction that converts…
The SCR system components include the: • reductant or Diesel Exhaust Fluid (DEF) • reductant tank • reductant dosing module • reductant pump and heater…
The following can be negatively affected by not using the recommended API rated engine oil are: • increased Particulate Matter (PM) in the aftertreatment system…
The electrical resistance of the sensor increases as the temperature increases, and resistance decreases as the temperature decreases. The varying resistance changes the voltage drop…
The EGT sensors are Resistance Temperature Detector (RTD) type sensors. The EGT sensors are inputs to the PCM. They measure the temperature of the exhaust…
The DPF pressure sensor is an input to the PCM and measures the pressure before the DPF. The sensor is a differential-type sensor that is…
The DPF is a highly engineered silicon carbide wall-flow catalyst that traps particulates, reducing the amount of black smoke emitted from the tailpipe. The three…
