The factors influencing the diagnosis and fixing cost of automobile fault code p1016 are the estimated repair time of 1.0 hour and the average hourly rate charged by auto repair shops, which ranges between $75 and $150.

The P1016 fault code refers to a problem with the Reductant Control Module Sensor Serial Communication Circuit. This sensor is responsible for measuring the quality of the reductant fluid in the reductant tank. It uses an ultrasonic signal and also has a temperature sensor to measure the fluid’s temperature.

The Reductant Quality Sensor communicates with the Reductant Control Module through serial data.

If the module detects a high circuit fault on the signal circuit for more than 1 second, it will trigger the P1016 fault code. This code indicates a potential issue with the communication between the sensor and the control module.

What are the possible causes for the automobile fault code P1016?

If you see the engine light on or the service engine soon warning light, the fault code P1016 could be the culprit. This code is often caused by a faulty reductant control module, an open or shorted harness, a poor electrical connection in the module circuit, or a faulty reductant quality sensor. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the P1016 fault code?

To fix the P1016 fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify if the fault lies in the Reductant Control Module or the Reductant Quality Sensor. Don’t forget to check the other possible causes mentioned above.

What should I look for when checking for damaged components and corroded connector pins to resolve the P1016 fault code?

When resolving the P1016 fault code, start by checking for damaged components and corroded connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of broken, bent, pushed out, or corroded pins. By addressing these issues, you can effectively fix the problem and prevent further complications.
