P203E: Your Car’s Fuel System Needs Attention
The P203E fault code indicates an issue with the reductant level sensor circuit. The sensor measures the tank level at three different heights using four stainless steel pins. The level sensor determines whether the tank level is above or below the respective level sensor position.
The measured level is used to update the calculation of remaining quantity in the reductant tank. The fault code may be triggered by an intermittent or erroneous signal from the sensor circuit. The sensor is limited to detecting liquid reductant and cannot detect frozen reductant.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P203E 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.
