Code P116F 2015 Chevrolet Silverado Description
The P116F diagnostic trouble code (DTC) for a 2015 Chevrolet Silverado refers to the O2 Pump Current Control Circuit High Voltage related to the NOx Sensor 1. This code indicates that there is a problem with the oxygen pump current control circuit, specifically that the voltage is higher than normal. The NOx sensor is responsible for monitoring the levels of nitrogen oxide in the exhaust gases and providing feedback to the engine control module (ECM) to adjust fuel mixture for optimal performance and emissions control.
Common Causes of P116F 2015 Chevrolet Silverado
- Faulty oxygen pump.
- Damaged wiring or connectors in the current control circuit.
- Malfunctioning NOx sensor.
- Issues with the ECM.
- Corrosion or contamination in the sensor connections.
Symptoms of P116F 2015 Chevrolet Silverado
- Check engine light illuminated on the dashboard.
- Reduced fuel efficiency.
- Decreased engine performance.
- Failed emissions tests.
- Rough idling or stalling.
How to Fix P116F 2015 Chevrolet Silverado
- Begin by using a diagnostic scan tool to retrieve the specific trouble code and further diagnose the issue.
- Inspect the wiring and connectors in the O2 pump current control circuit for any damage or corrosion. Repair or replace as necessary.
- Test the NOx sensor to ensure it is functioning correctly. Replace if faulty.
- Check the oxygen pump for proper operation and replace if needed.
- Clear the trouble code from the ECM's memory and test drive the vehicle to ensure the issue has been resolved.
