Code P116D 2017 Chevrolet Silverado Description
The P116D code on a 2017 Chevrolet Silverado indicates a problem with the O2 pump current control circuit related to NOx Sensor 1. This code specifically points to an issue with the oxygen sensor pump that controls the current in the circuit for the NOx (nitrogen oxide) sensor. The NOx sensor is responsible for monitoring the levels of nitrogen oxide in the exhaust gases to ensure compliance with emissions standards.
Common Causes of P116D 2017 Chevrolet Silverado
- Faulty oxygen sensor pump
- Malfunctioning NOx sensor
- Electrical issues in the circuit
- Wiring harness problems
- Corrosion or damage to connectors
Symptoms of P116D 2017 Chevrolet Silverado
- Decreased fuel efficiency
- Rough idling
- Hesitation during acceleration
- Stalling
How to Fix P116D 2017 Chevrolet Silverado
- Begin by conducting a thorough inspection of the O2 pump current control circuit and NOx sensor to identify any visible damage or issues.
- Test the oxygen sensor pump and NOx sensor using a multimeter to check for proper functionality.
- Inspect the wiring harness for any signs of damage, corrosion, or loose connections, and repair or replace as needed.
- Clear the diagnostic trouble codes from the vehicle's computer and reset the system to see if the issue persists.
- If the problem persists, consider replacing the oxygen sensor pump or NOx sensor to resolve the issue.
