P1018 Fault Code: Understanding The Description And Troubleshooting Steps
The P1018 fault code refers to a problem with the Reductant Control Module Sensor Communication Voltage Supply Circuit. This circuit is responsible for supplying voltage to the Reductant Quality Sensor, which is located in the reductant tank of the vehicle. The Reductant Quality Sensor uses an ultrasonic signal to measure the quality of the reductant fluid and also includes a temperature sensor to measure the fluid’s temperature.
When the Reductant Control Module detects a short to ground on the 5 V reference circuit for more than 1 second, it will trigger the P1018 fault code.
This means that there is a low voltage supply issue with the communication between the Reductant Control Module and the Reductant Quality Sensor.
It is important to address this issue promptly to ensure proper functioning of the reductant system in the vehicle.
