P2207 2016 Chevrolet Silverado Code - NOx Sensor 1 Heater Control Circuit High Voltage
Quick Answer
The P2207 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a problem with the NOx (nitrogen oxide) sensor 1 heater control circuit registering high voltage. Common causes include Faulty NOx Sensor: The NOx sensor itself may be malfunctioning, causing the heater control circuit to register high voltage, Wiring Issues: Damage or corrosion in the wiring harness connected to the NOx sensor can disrupt the electrical flow and trigger the code, Faulty Connector: A loose or damaged connector between the sensor and the PCM can lead to high voltage readings in the heater control circuit. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2207 2016 Chevrolet Silverado Description
The P2207 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a problem with the NOx (nitrogen oxide) sensor 1 heater control circuit registering high voltage. The NOx sensor is a crucial component in the vehicle's emissions control system, responsible for monitoring and regulating the levels of nitrogen oxides in the exhaust gases. The heater control circuit is designed to maintain the sensor at an optimal operating temperature for accurate readings.
Common Causes of P2207 2016 Chevrolet Silverado
- Faulty NOx Sensor: The NOx sensor itself may be malfunctioning, causing the heater control circuit to register high voltage.
- Wiring Issues: Damage or corrosion in the wiring harness connected to the NOx sensor can disrupt the electrical flow and trigger the code.
- Faulty Connector: A loose or damaged connector between the sensor and the PCM can lead to high voltage readings in the heater control circuit.
- PCM Malfunction: A problem with the powertrain control module responsible for monitoring the NOx sensor could cause the circuit to register high voltage.
- Environmental Factors: Exposure to extreme temperatures or moisture can also impact the NOx sensor's performance and trigger the P2207 code.
Symptoms of P2207 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 malfunctioning NOx sensor heater control circuit can lead to decreased fuel efficiency as the engine may not be operating at optimal emissions levels.
- Failed Emissions Test: If the NOx sensor is not functioning correctly, the vehicle may fail emissions tests due to higher than allowed nitrogen oxide emissions.
- Rough Idle: In some cases, a faulty NOx sensor heater control circuit can cause the engine to idle roughly or inconsistently.
- Poor Performance: The vehicle may experience a decrease in overall performance, including reduced power output and acceleration.
How to Fix P2207 2016 Chevrolet Silverado
- Diagnostic Scan: Use an OBD-II scanner to retrieve the specific trouble code and verify the issue with the NOx sensor 1 heater control circuit.
- Inspect Wiring and Connectors: Check the wiring harness and connectors for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test NOx Sensor: Test the NOx sensor itself to determine if it is functioning correctly. Replace the sensor if it is found to be faulty.
- Check PCM: Inspect the powertrain control module for any signs of malfunction or damage. Reset or replace the PCM if necessary.
- Clear Codes and Test Drive: Clear the diagnostic trouble codes from the vehicle's system and test drive to ensure the issue has been resolved.
Cost to Fix P2207 2016 Chevrolet Silverado
The typical repair costs for addressing a P2207 code on a 2016 Chevrolet Silverado can vary depending on the specific cause of the issue. In general, replacing a faulty NOx sensor can cost between $200 and $500, while repairing wiring or connectors may range from $100 to $300. If the PCM needs to be replaced, the cost can be higher, typically ranging from $500 to $1000. Labor costs at auto repair shops can vary between $80 and $150 per hour, so the total repair bill can add up based on the required repairs and the shop's hourly rate. It's advisable to consult with a certified mechanic or dealership for a more accurate estimate based on the specific diagnosis and repair needs of the vehicle.
