P203C: Unveiling The Mystery Behind Your Car’s Fuel Temperature Sensor
The P203C code indicates a problem with the reductant level sensor circuit. The sensor measures the tank level at three different heights using four stainless steel pins.
Only three pins are used for level evaluation, while the fourth is used as a ground pin. The 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.
The code may be triggered if the sensor circuit is experiencing low voltage.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P203C fault code. This code is usually caused by a faulty reductant level sensor, an open or shorted reductant level sensor harness, or a poor electrical connection in the reductant level sensor circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light, it could be due to a faulty Reductant Level Sensor or an open/shorted harness. To fix this issue, start by visually inspecting the wiring harness and connectors related to the sensor. Check for any damaged components and look for broken, bent, pushed out, or corroded connector pins. This will help you identify any poor electrical connections and get your vehicle back on track.
If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the P203C fault code, you should replace or repair them as necessary.
