Code P1016 Description
The P1016 code indicates a problem with the reductant control module sensor serial communication circuit having high voltage. The reductant control module is responsible for managing the injection of diesel exhaust fluid (DEF) into the exhaust system to reduce emissions. The sensor communicates with the module to ensure the proper amount of DEF is injected. When the communication circuit is experiencing high voltage, it can lead to incorrect readings and potentially affect the vehicle's emissions performance. If left unaddressed, this issue can result in increased emissions, reduced fuel efficiency, and potential damage to the exhaust system.
Common Causes of P1016
- Faulty reductant control module sensor
- Wiring issues or shorts in the communication circuit
- Corrosion or damage to sensor connectors
- Software or programming issues
- Issues with the reductant control module itself
Symptoms of P1016
- Check engine light is illuminated
- Reduced fuel efficiency
- Poor engine performance
- Failed emissions test
- Rough idling or stalling
How to Fix P1016
- Diagnose the specific cause of the high voltage in the sensor communication circuit
- Inspect wiring and connectors for damage or corrosion
- Test the reductant control module sensor for proper function
- Repair or replace faulty components as necessary
- Clear the diagnostic trouble codes and reset the system for proper operation
Cost to Fix P1016
The typical repair costs for addressing a P1016 code can range from $200 to $500, depending on the specific cause of the issue and the cost of replacement parts. It's important to consider the labor rates at auto repair shops, which can vary based on location and the type of shop. It's advisable to obtain quotes from multiple shops to ensure a fair price for the repair.
