What are the possible causes of the P20AF fault code in an automobile?

The P20AF fault code in an automobile is indicated by the Engine Light ON or Service Engine Soon Warning Light. The possible causes of this fault code are a faulty Reductant Metering Unit Temperature Sensor, an open or shorted Reductant Metering Unit Temperature Sensor harness, or a poor electrical connection in the Reductant Metering Unit Temperature Sensor circuit. To fix this issue, one 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.

How can one visually inspect the wiring harness and connectors related to the Reductant Metering Unit Temperature Sensor?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light), it could be due to a faulty Reductant Metering Unit Temperature Sensor. 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. This will help you identify if the Reductant Metering Unit Temperature Sensor harness is open or shorted, or if there is a poor electrical connection in the circuit.

What are the consequences of ignoring the P20AF fault code in an automobile?

Ignoring the P20AF fault code in an automobile can lead to serious consequences. The engine light will remain on, indicating a problem with the Reductant Metering Unit Temperature Sensor. This can result in decreased fuel efficiency, increased emissions, and potential damage to the engine. It is important to address the issue by visually inspecting the wiring harness and connectors, checking for damaged components, and fixing any issues found.
