Code P116F 2014 Chevrolet Silverado Description
The P116F diagnostic trouble code (DTC) in a 2014 Chevrolet Silverado indicates an issue with the O2 pump current control circuit, specifically relating to high voltage in the NOx sensor 1. The NOx sensor, or nitrogen oxide sensor, is a crucial component in the vehicle's emissions control system, responsible for monitoring and regulating the levels of nitrogen oxides in the exhaust gases. The O2 pump current control circuit is designed to manage the operation of the NOx sensor by adjusting the current flow to maintain optimal performance.
Common Causes of P116F 2014 Chevrolet Silverado
- Faulty O2 pump current control circuit
- Wiring or connector issues in the NOx sensor circuit
- Malfunctioning NOx sensor
- Engine misfires or running rich/lean
- Software or calibration issues
Symptoms of P116F 2014 Chevrolet Silverado
- Decreased fuel efficiency
- Increased emissions output
- Rough idling
- Reduced engine performance
- Stalling
How to Fix P116F 2014 Chevrolet Silverado
- Begin by conducting a thorough inspection of the O2 pump current control circuit, NOx sensor, wiring, and connectors for any visible damage or corrosion.
- Test the NOx sensor and O2 pump current control circuit using a multimeter to check for proper voltage levels and continuity.
- Replace any faulty components, such as the NOx sensor, O2 pump current control circuit, or damaged wiring/connectors.
- Clear the DTC from the vehicle's computer using an OBD-II scanner and perform a test drive to ensure the issue has been resolved.
- If the problem persists, consult a professional mechanic or dealership for further diagnostics and potential software updates or recalibrations.
Cost to Fix P116F 2014 Chevrolet Silverado
