Code P116F 2015 GMC Sierra Description
The P116F diagnostic trouble code (DTC) for a 2015 GMC Sierra relates to the O2 Pump Current Control Circuit High Voltage, specifically for the NOx Sensor 1. This code indicates that there is a problem with the circuit that controls the current for 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 providing feedback to the engine control module (ECM) to adjust fuel mixture and emissions.
Common Causes of P116F 2015 GMC Sierra
- Faulty O2 pump
- Wiring issues in the current control circuit
- Malfunctioning NOx sensor
- ECM software glitch
- Corrosion or damage to electrical connections
Symptoms of P116F 2015 GMC Sierra
- Decreased fuel efficiency
- Engine misfires or hesitation
- Illuminated check engine light
- Rough idling
- Increased emissions
How to Fix P116F 2015 GMC Sierra
- Diagnose the issue using a scan tool to verify the P116F code and identify the specific component causing the problem.
- Inspect the wiring and electrical connections related to the O2 pump current control circuit for any damage or corrosion.
- Test the O2 pump and NOx sensor to determine if they are functioning properly.
- Replace any faulty components, such as the O2 pump, NOx sensor, or wiring harness.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
Cost to Fix P116F 2015 GMC Sierra

Frequently Asked Questions about P116F 2015 GMC Sierra Code
What does the OBDII code P116F mean for a 2015 GMC Sierra?
P116F indicates an issue with the O2 Pump Current Control Circuit High Voltage in NOx Sensor 1, meaning the sensor is detecting higher-than-expected voltage in the circuit.
What are the common symptoms of code P116F in a 2015 GMC Sierra?
Common symptoms include the Check Engine Light being illuminated, reduced engine performance, increased fuel consumption, and potential difficulty passing emissions tests.
What causes the P116F code to appear on a 2015 GMC Sierra?
The code can be triggered by a faulty NOx sensor, damaged wiring or connectors, a malfunctioning ECM (Engine Control Module), or a buildup of carbon or contaminants in the exhaust system.
Can I drive my 2015 GMC Sierra with the P116F code active?
While the vehicle may still be drivable, it is not recommended to ignore the issue as it can lead to reduced performance, higher emissions, and potential damage to other components.
How do I diagnose the P116F code on a 2015 GMC Sierra?
Start by using an OBDII scanner to confirm the code, inspect the NOx sensor and its wiring for damage, and check for loose or corroded connectors. Advanced diagnostics may require testing the sensor's voltage and current readings.
What tools are needed to fix the P116F code on a 2015 GMC Sierra?
You may need an OBDII scanner, a multimeter for electrical testing, and basic hand tools for removing and replacing the NOx sensor or repairing wiring.
How much does it cost to fix a P116F code on a 2015 GMC Sierra?
The cost varies depending on the issue. Replacing the NOx sensor can cost $300–$700, while repairing wiring or connectors is typically less expensive.
Can a P116F code be caused by a software issue in the 2015 GMC Sierra?
Yes, in some cases, a software update for the ECM may be required to resolve the issue, especially if the code persists after replacing the NOx sensor.
How do I prevent the P116F code from returning on my 2015 GMC Sierra?
Regular maintenance, using high-quality fuel, and ensuring the exhaust system is clean can help prevent this issue. Additionally, promptly addressing any wiring or sensor problems can reduce the risk of recurrence.
Is it necessary to replace the NOx sensor to fix the P116F code?
Not always. While a faulty NOx sensor is a common cause, the issue could also stem from damaged wiring, connectors, or ECM problems, so a proper diagnosis is essential before replacing the sensor.
