Sensor failure is a possible culprit, so inspect the reductant quality sensor and its connections.

The P1016 code can lead to reduced engine performance and difficulty starting the vehicle, so it’s essential to address the problem promptly.

Possible Causes of P1016 Code

Five common culprits can trigger the P1016 code, and you’ll need to investigate each one to identify the root cause of the issue.

Sensor failure is a possible cause, specifically a faulty Reductant Quality Sensor.

Wiring issues, such as an open or shorted Reductant Control Module harness or poor electrical connections, can also trigger the code.

Additionally, a faulty Reductant Control Module itself or other unlisted causes might be the root of the problem.

You’ll need to methodically check each potential cause to determine the source of the issue.

Description and Symptoms of P1016 Code

The Reductant Quality Sensor plays a pivotal role in monitoring reductant fluid quality and temperature.

As you diagnose the P1016 code, it’s essential to understand the sensor’s functions and how they impact your vehicle’s performance.

The sensor communicates with the Reductant Control Module using serial data, and a high circuit fault on the signal circuit for over 1 second sets the Diagnostic Trouble Code (DTC).

• You may notice the Engine Light ON (or Service Engine Soon Warning Light) and reduced engine performance, making it difficult to start the vehicle.
• The sensor measures reductant fluid quality and temperature, ensuring efficient engine operation.
• Faulty sensor functions can lead to decreased engine performance and starting issues.
• The Reductant Quality Sensor is a key component in maintaining ideal engine conditions.
• Understanding the sensor’s role in reductant quality monitoring is essential for accurate diagnosis and repair.

How to Fix P1016 Code

You’ll need to methodically inspect the vehicle’s electrical system to fix the P1016 code.

Start by checking the possible causes, such as a faulty Reductant Control Module or poor electrical connections.

Visually inspect the related wiring harness and connectors, looking for damaged components or broken pins.

Repair or replace any damaged parts as needed.

Clear the code and see if it returns.

With Car Troubleshooting and Smart Repair techniques, you can efficiently diagnose and fix the issue.

Remember to check the sensor serial communication circuit for high voltage levels, a common trigger for the P1016 code.

P1016 Code Diagnosis

Diagnosing the P1016 code requires a thorough understanding of the reductant control module sensor’s serial communication circuit.

Thorough understanding of the reductant control module sensor’s serial communication circuit is crucial for diagnosing the P1016 code.

You’ll need to investigate the sensor’s signal circuit, checking for high voltage levels that can trigger the code. Perform sensor testing to identify any issues with the reductant quality sensor, and conduct module troubleshooting to rule out problems with the reductant control module.

• Check the wiring and connections related to the reductant control module sensor for damage or corrosion.
• Use a scan tool to monitor the sensor’s serial data communication.
• Verify the reductant quality sensor’s operation and calibration.
• Consult the vehicle’s repair manual for specific diagnosis procedures.
• Consider using a wiring diagram to aid in your diagnosis.
