P1004 2017 Chevrolet Silverado Code - NOx Sensor 2 Slow Response
Quick Answer
The P1004 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates a problem with the NOx (nitrogen oxide) Sensor 2 slow response. Common causes include Faulty NOx Sensor 2: The sensor itself may be malfunctioning, leading to a slow response, Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can cause communication problems, ECM Malfunction: A problem with the engine control module can prevent it from receiving and processing data from the sensor. 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 P1004 2017 Chevrolet Silverado Description
The P1004 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates a problem with the NOx (nitrogen oxide) Sensor 2 slow response. This sensor is responsible for monitoring the levels of nitrogen oxide in the exhaust gases to ensure compliance with emissions regulations. A slow response from the sensor can lead to inaccurate readings being sent to the engine control module (ECM), potentially causing issues with the vehicle's performance and emissions.
Common Causes of P1004 2017 Chevrolet Silverado
- Faulty NOx Sensor 2: The sensor itself may be malfunctioning, leading to a slow response.
- Wiring Issues: Damaged or corroded wiring connecting the sensor to the ECM can cause communication problems.
- ECM Malfunction: A problem with the engine control module can prevent it from receiving and processing data from the sensor.
- Exhaust System Leaks: Leaks in the exhaust system can affect the sensor's readings, causing a slow response.
- Software/Programming Issues: Issues with the software or programming of the ECM can also contribute to the slow response of the sensor.
Symptoms of P1004 2017 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P1004 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A slow response from the NOx Sensor 2 can lead to decreased fuel efficiency as the engine may not be operating optimally.
- Poor Engine Performance: The vehicle may experience rough idling, hesitation, or lack of power due to inaccurate sensor readings.
- Failed Emissions Test: If the NOx levels are not accurately monitored, the vehicle may fail emissions tests due to excessive nitrogen oxide emissions.
How to Fix P1004 2017 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific trouble code and perform tests to determine the exact cause of the slow response from the NOx Sensor 2.
- Inspect Wiring and Connections: Check the wiring harness and connections for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test the NOx Sensor 2: Test the sensor itself to verify if it is functioning correctly. Replace the sensor if it is found to be faulty.
- Check ECM Functionality: Verify that the engine control module is operating properly and receiving data from the sensor. Address any ECM issues if necessary.
- Clear Codes and Test Drive: Clear the diagnostic trouble codes from the ECM, then test drive the vehicle to ensure the issue has been resolved and the check engine light does not reappear.
Cost to Fix P1004 2017 Chevrolet Silverado
The typical repair costs for addressing a P1004 code related to a NOx Sensor 2 slow response in a 2017 Chevrolet Silverado can range from $200 to $500, including parts and labor. However, it's important to note that the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Auto repair shops commonly charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships, while independent shops often charge less. It is advisable to check local rates for a more precise estimate before proceeding with the repair.
