P203A: Uncovering The Mystery Behind Your Car’s Check Engine Light
The P203A fault code refers to the reductant level sensor circuit in an automobile. The sensor measures the tank level at three different heights using four high-grade stainless steel pins. The level sensor determines whether the tank level is above or below the respective level sensor position based on the electrical conductivity of Urea.
The measured level is used to update the calculation of remaining quantity in the reductant tank, but frozen reductant cannot be detected.
The information from the level sensor is directly evaluated by the ECU.
