Code P0222 2016 GMC Sierra Description
The P0222 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates an issue with the Throttle Position Sensor 2 Circuit registering low voltage. The throttle position sensor (TPS) is a crucial component of the vehicle's electronic throttle control system, responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). TPS 2 specifically refers to the secondary throttle position sensor in the system.
Common Causes of P0222 2016 GMC Sierra
- Faulty Throttle Position Sensor 2.
- Wiring issues or loose connections in the TPS 2 circuit.
- Corrosion or damage to the TPS 2 connector.
- ECM software or hardware malfunction affecting TPS readings.
- Environmental factors such as moisture or debris affecting sensor operation.
Symptoms of P0222 2016 GMC Sierra
- Poor acceleration or hesitation when pressing the throttle pedal.
- Rough idling or stalling when coming to a stop.
- Reduced engine power or lack of response from the throttle.
- Check Engine Light illuminated on the dashboard.
- Vehicle entering limp mode to protect the engine from potential damage.
How to Fix P0222 2016 GMC Sierra
- Begin by verifying the P0222 code using an OBD-II scanner to confirm the issue.
- Inspect the TPS 2 wiring harness and connector for any signs of damage or corrosion.
- Test the Throttle Position Sensor 2 using a multimeter to check for proper voltage output.
- If the TPS 2 is faulty, replace it with a new sensor following manufacturer guidelines.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0222 2016 GMC Sierra
The typical repair costs for addressing a P0222 code on a 2016 GMC Sierra can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor. It's important to note that diagnosis time and labor rates at auto repair shops can vary, with hourly rates typically falling between $80 and $150. Factors such as location, vehicle make and model, and engine type can also influence the overall repair costs. For a more accurate estimate, it's recommended to consult with local auto repair shops.

Frequently Asked Questions about P0222 2016 GMC Sierra Code
1. What does the OBDII code P0222 mean on a 2016 GMC Sierra?
P0222 indicates that the Throttle Position Sensor (TPS) 2 circuit is detecting a voltage lower than the expected range.
2. What are the symptoms of the P0222 code on a 2016 GMC Sierra?
Common symptoms include reduced engine power, difficulty accelerating, the throttle not responding properly, and the "Check Engine" or "Reduced Power" light illuminating.
3. What causes the P0222 code to appear on a 2016 GMC Sierra?
Potential causes include a faulty Throttle Position Sensor, damaged wiring or connections in the TPS circuit, a faulty throttle body, or issues with the Powertrain Control Module (PCM).
4. Can I drive my 2016 GMC Sierra with the P0222 code?
It’s not recommended to drive the vehicle, as it may experience reduced power or unsafe throttle response, which could be dangerous in certain driving conditions.
5. How is the P0222 code diagnosed on a 2016 GMC Sierra?
A mechanic will use a scan tool to confirm the code, inspect the wiring and connections for the TPS, test the voltage and resistance of the sensor, and check for any other related codes.
6. How do you fix the P0222 code on a 2016 GMC Sierra?
Repairs may involve replacing the Throttle Position Sensor, repairing damaged wiring or connectors, cleaning or replacing the throttle body, or reprogramming the PCM if necessary.
7. What tools are needed to troubleshoot the P0222 code?
Common tools include an OBDII scanner, a multimeter to test voltage and resistance, and basic hand tools for inspecting and replacing components.
8. How much does it cost to repair the P0222 code on a 2016 GMC Sierra?
The cost depends on the specific issue; replacing a Throttle Position Sensor typically costs between $100 and $300, while more extensive repairs like throttle body replacement or PCM reprogramming may cost more.
9. What is the role of Throttle Position Sensor 2 in a 2016 GMC Sierra?
TPS 2 monitors the position of the throttle plate and sends voltage signals to the PCM to help control engine performance and throttle response.
10. Can a dirty throttle body cause the P0222 code on a 2016 GMC Sierra?
Yes, a dirty throttle body can cause incorrect readings from the TPS, potentially triggering the P0222 code. Cleaning the throttle body may resolve the issue in some cases.
