Code P116F 2016 Chevrolet Silverado Description
The P116F diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado refers to an issue with the O2 Pump Current Control Circuit High Voltage, specifically related to the NOx Sensor 1. This code indicates that there is a problem with the control circuit that manages the current flow to the O2 pump, which is crucial for the proper functioning of the NOx sensor. The NOx sensor is responsible for monitoring the levels of nitrogen oxide in the exhaust gases and plays a key role in emissions control.
Common Causes of P116F 2016 Chevrolet Silverado
- Faulty O2 Pump: A malfunctioning O2 pump can cause irregular current flow in the control circuit, leading to high voltage readings.
- Wiring Issues: Damaged or corroded wiring connections can disrupt the current flow and trigger this code.
- Sensor Malfunction: A malfunctioning NOx sensor can also contribute to high voltage readings in the O2 pump current control circuit.
- ECM/PCM Failure: A failure in the engine control module or powertrain control module can result in communication errors that trigger this code.
- Exhaust System Leaks: Leaks in the exhaust system can affect the readings of the NOx sensor and lead to issues with the O2 pump current control circuit.
Symptoms of P116F 2016 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A malfunctioning O2 Pump Current Control Circuit can lead to decreased fuel efficiency as the engine may not be operating at optimal levels.
- Rough Idling: The engine may experience rough idling or hesitation when the O2 pump current control circuit is not functioning correctly.
- Increased Emissions: High levels of nitrogen oxide emissions may be detected due to the inaccurate readings from the NOx sensor.
- Reduced Engine Performance: The vehicle may exhibit reduced engine performance or power output as a result of the disrupted emissions control system.
How to Fix P116F 2016 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific trouble code and perform a thorough inspection of the O2 pump, wiring, and sensors to identify the root cause of the problem.
- Replace Faulty Components: Replace any faulty O2 pump, wiring connections, NOx sensor, or ECM/PCM that are contributing to the high voltage readings in the control circuit.
- Clear Error Codes: After making the necessary repairs, clear the error codes from the vehicle's system to reset the check engine light.
- Test Drive: Take the vehicle for a test drive to ensure that the issue has been resolved and that the emissions control system is functioning properly.
- Regular Maintenance: To prevent future occurrences of this code, perform regular maintenance on the vehicle's emissions control system, including checking and replacing components as needed.
Cost to Fix P116F 2016 Chevrolet Silverado
The typical repair costs for addressing a P116F code on a 2016 Chevrolet Silverado can vary depending on the specific components that need to be replaced and the labor rates at the auto repair shop. On average, the cost of parts for this repair can range from $200 to $500, while the labor costs can range from $150 to $300. Keep in mind that these are rough estimates, and actual costs may vary based on the location, vehicle make and model, and the extent of the repairs needed.

Frequently Asked Questions about P116F 2016 Chevrolet Silverado Code
1. What does the OBDII code P116F mean on a 2016 Chevrolet Silverado?
P116F indicates a high voltage issue in the O2 Pump Current Control Circuit for NOx Sensor 1, which monitors nitrogen oxide levels in the exhaust system.
2. What are the common symptoms of code P116F in a 2016 Chevrolet Silverado?
Symptoms may include the check engine light turning on, reduced fuel efficiency, poor engine performance, or increased emissions.
3. What causes the P116F code in a 2016 Chevrolet Silverado?
Common causes include a faulty NOx sensor, damaged wiring or connectors in the sensor circuit, or issues with the engine control module (ECM).
4. Can I drive my 2016 Chevrolet Silverado with the P116F code?
While the truck may still be drivable, it’s not recommended as it can lead to increased emissions and potential damage to the exhaust system over time.
5. How do I diagnose the P116F code on a 2016 Chevrolet Silverado?
Diagnosis involves checking the NOx sensor wiring and connectors for damage, testing the sensor itself, and using a scan tool to monitor live data from the O2 Pump Current Control Circuit.
6. How do I fix the P116F code on my 2016 Chevrolet Silverado?
Repairs may include replacing the faulty NOx sensor, repairing or replacing damaged wiring, or updating/reprogramming the ECM if necessary.
