P0667 2017 Chevrolet Silverado Code - Control Module Temperature Sensor Performance
Quick Answer
The P0667 diagnostic trouble code (DTC) in a 2017 Chevrolet Silverado indicates a problem with the control module temperature sensor's performance. Common causes include Faulty Control Module Temperature Sensor: The sensor itself may be malfunctioning, providing incorrect temperature data to the ECM/PCM, Wiring Issues: Corrosion, breaks, or shorts in the wiring harness connecting the sensor to the ECM/PCM can disrupt signal transmission, ECM/PCM Malfunction: A faulty ECM/PCM may not accurately interpret the temperature sensor's data, triggering the P0667 code. 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 P0667 2017 Chevrolet Silverado Description
The P0667 diagnostic trouble code (DTC) in a 2017 Chevrolet Silverado indicates a problem with the control module temperature sensor's performance. The control module temperature sensor is responsible for monitoring the temperature of the engine control module (ECM) or powertrain control module (PCM). This sensor plays a crucial role in ensuring that the ECM/PCM operates within the optimal temperature range for proper functioning.
Common Causes of P0667 2017 Chevrolet Silverado
- Faulty Control Module Temperature Sensor: The sensor itself may be malfunctioning, providing incorrect temperature data to the ECM/PCM.
- Wiring Issues: Corrosion, breaks, or shorts in the wiring harness connecting the sensor to the ECM/PCM can disrupt signal transmission.
- ECM/PCM Malfunction: A faulty ECM/PCM may not accurately interpret the temperature sensor's data, triggering the P0667 code.
- Extreme Temperatures: Exposure to extreme heat or cold can damage the control module temperature sensor over time.
Symptoms of P0667 2017 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P0667 code is the illumination of the check engine light on the dashboard.
- Poor Engine Performance: The vehicle may experience reduced power, hesitation, or rough idling due to incorrect temperature readings.
- Decreased Fuel Efficiency: A faulty control module temperature sensor can lead to increased fuel consumption.
- Engine Stalling: In severe cases, the engine may stall or have difficulty starting.
- Overheating: The vehicle may run hotter than usual if the control module temperature sensor is providing inaccurate readings.
How to Fix P0667 2017 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble codes and perform a thorough inspection of the control module temperature sensor and related components.
- Replace the Control Module Temperature Sensor: If the sensor is faulty, replace it with a new, OEM-quality sensor to ensure accurate temperature readings.
- Check Wiring: Inspect the wiring harness for any signs of damage, corrosion, or breaks. Repair or replace any damaged wiring as needed.
- Test ECM/PCM: Verify that the ECM/PCM is functioning correctly and accurately interpreting the temperature sensor's data.
- Clear Codes and Test Drive: Clear the DTCs from the vehicle's memory, reset the ECM/PCM, and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0667 2017 Chevrolet Silverado
The typical repair costs for addressing a P0667 code in a 2017 Chevrolet Silverado can range from $150 to $400, including parts and labor. However, 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. Most auto repair shops charge between $80 and $150 per hour for labor. Rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less. It's advisable to check local rates for a more precise estimate.
