Code P116F 2018 Chevrolet Silverado Description
The P116F diagnostic trouble code (DTC) in a 2018 Chevrolet Silverado indicates an issue with the O2 pump current control circuit, specifically related to the NOx sensor 1. The NOx sensor is responsible for monitoring the levels of nitrogen oxide in the exhaust gases to ensure compliance with emissions regulations. When the O2 pump current control circuit detects a high voltage, it means that the signal being sent by the NOx sensor is outside of the expected range.
Common Causes of P116F 2018 Chevrolet Silverado
- Faulty NOx sensor
- Wiring or connection issues in the O2 pump current control circuit
- Exhaust leaks
- Engine running rich
- Issues with the powertrain control module (PCM)
Symptoms of P116F 2018 Chevrolet Silverado
- Decreased fuel efficiency
- Engine misfires
- Check engine light illuminated
- Rough idling
- Failed emissions test
How to Fix P116F 2018 Chevrolet Silverado
- Diagnose the issue using a scan tool to pinpoint the exact cause of the high voltage reading.
- Inspect the NOx sensor and the wiring/connectors for any visible damage or corrosion.
- Test the O2 pump current control circuit for proper voltage output.
- Replace the NOx sensor if it is found to be faulty.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
