Code P116E 2017 Chevrolet Silverado Description
The P116E diagnostic trouble code (DTC) in a 2017 Chevrolet Silverado specifically refers to the O2 Pump Current Control Circuit Low Voltage related to the NOx Sensor 1. This code indicates that there is an issue with the oxygen sensor (O2) pump current control circuit, resulting in a lower than expected voltage in the NOx Sensor 1. The NOx sensor is responsible for monitoring the levels of nitrogen oxide in the exhaust system to ensure compliance with emissions regulations and to optimize the performance of the selective catalytic reduction (SCR) system.
Common Causes of P116E 2017 Chevrolet Silverado
- Faulty O2 pump current control circuit
- Damaged NOx Sensor 1
- Wiring or connection issues
- Defective SCR system
- Software or calibration errors
Symptoms of P116E 2017 Chevrolet Silverado
- Rough engine idle
- Reduced power and acceleration
- Poor fuel efficiency
- Failed emissions test
- Check engine light illuminated
How to Fix P116E 2017 Chevrolet Silverado
- Diagnose the issue with a scan tool to verify the P116E code and pinpoint the exact cause of the problem.
- Inspect the O2 pump current control circuit, NOx Sensor 1, wiring, and connections for any signs of damage or corrosion.
- Replace the faulty components, such as the O2 pump current control circuit or NOx Sensor 1, if necessary.
- Clear the DTCs from the vehicle's memory and reset the check engine light.
- Test drive the vehicle to ensure the issue has been resolved and that all systems are functioning properly.
Cost to Fix P116E 2017 Chevrolet Silverado
The typical repair costs for addressing the P116E code in a 2017 Chevrolet Silverado can vary depending on the specific cause of the issue and the parts/labour required. Generally, the cost of parts for replacing the O2 pump current control circuit or NOx Sensor 1 can range from $100 to $300, while labour costs can add another $100 to $200. Therefore, the total repair cost may be approximately $200 to $500. It's important to note that these are rough estimates, and actual costs may vary based on location, vehicle make and model, and other factors. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate cost assessment.
