P2202 2016 Chevrolet Silverado Code - NOx Sensor 1 Circuit Low Voltage
Quick Answer
The P2202 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado refers to an issue with the NOx (Nitrogen Oxide) Sensor 1 Circuit registering low voltage. Common causes include Faulty NOx Sensor: The NOx sensor itself may be malfunctioning, causing low voltage readings, Wiring or Connector Damage: Damage to the wiring or connectors associated with the NOx sensor can lead to low voltage readings, PCM Malfunction: A problem with the powertrain control module (PCM) could prevent proper communication with the NOx sensor. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2202 2016 Chevrolet Silverado Description
The P2202 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado refers to an issue with the NOx (Nitrogen Oxide) Sensor 1 Circuit registering low voltage. The NOx sensor is a crucial component in the vehicle's emissions control system, responsible for monitoring and regulating the levels of nitrogen oxide emissions. When the NOx sensor detects low voltage in its circuit, it indicates a potential problem with the sensor itself or the wiring and connections associated with it.
Common Causes of P2202 2016 Chevrolet Silverado
- Faulty NOx Sensor: The NOx sensor itself may be malfunctioning, causing low voltage readings.
- Wiring or Connector Damage: Damage to the wiring or connectors associated with the NOx sensor can lead to low voltage readings.
- PCM Malfunction: A problem with the powertrain control module (PCM) could prevent proper communication with the NOx sensor.
- Exhaust System Issues: Problems within the exhaust system, such as leaks or blockages, can impact the NOx sensor's performance.
- Environmental Factors: Extreme temperatures or exposure to harsh conditions can also contribute to NOx sensor issues.
Symptoms of P2202 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.
- Reduced Fuel Efficiency: A decrease in fuel efficiency may be noticed due to the engine running inefficiently.
- Poor Acceleration: The vehicle may experience hesitation or lack of power during acceleration.
- Failed Emissions Test: If the NOx levels are out of range, the vehicle may fail emissions testing.
- Rough Idle: The engine may idle roughly or inconsistently due to the NOx sensor issue.
How to Fix P2202 2016 Chevrolet Silverado
- Diagnostic Scan: Begin by using a diagnostic scan tool to retrieve the specific trouble code and confirm the NOx sensor 1 circuit low voltage issue.
- Inspection: Inspect the NOx sensor, wiring, and connectors for any visible damage or corrosion. Replace any faulty components.
- Test NOx Sensor: Test the NOx sensor's functionality using a multimeter or specialized diagnostic equipment to ensure it is operating within specifications.
- Check Exhaust System: Inspect the exhaust system for leaks, damage, or blockages that could affect the NOx sensor's readings.
- Clear Codes: After completing the repairs, clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2202 2016 Chevrolet Silverado
The typical repair costs for addressing a P2202 NOx Sensor 1 Circuit Low Voltage code on a 2016 Chevrolet Silverado can vary depending on the specific cause of the issue. In general, the cost of replacing a faulty NOx sensor, repairing damaged wiring or connectors, or addressing exhaust system problems can range from $200 to $600 or more.
