Code P203C Ford Description
The level sensor consists of four high-grade stainless steel pins. The length of each pin defines the tank level (height) which is to be checked. Only three pins can be used for level evaluation. The fourth pin is used as ground pin. Due to the electrical conductivity of Urea the level sensor will determine whether the tank level is above or below the respective level sensor position. This information will be directly evaluated by the ECU.
