P0697 2014 Chevrolet Silverado Code - 5 Volt Reference 3 Circuit
Quick Answer
The P0697 code in a 2014 Chevrolet Silverado indicates a problem with the 5-volt reference 3 circuit. Common causes include Faulty 5-Volt Reference Circuit: The most common cause of the P0697 code is a malfunction in the 5-volt reference 3 circuit itself, which can be caused by wiring issues, corrosion, or a short circuit, Faulty Sensor: A faulty sensor connected to the 5-volt reference 3 circuit, such as a throttle position sensor or mass airflow sensor, can trigger this code, ECM/PCM Malfunction: A malfunction in the engine control module or powertrain control module can also lead to the P0697 code being triggered. 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 P0697 2014 Chevrolet Silverado Description
The P0697 code in a 2014 Chevrolet Silverado indicates a problem with the 5-volt reference 3 circuit. The 5-volt reference circuit is an essential component in modern vehicles, as it provides a stable source of 5 volts to various sensors and components throughout the vehicle. This stable voltage is crucial for the proper functioning of these sensors and components, as it allows them to provide accurate data to the vehicle's engine control module (ECM) or powertrain control module (PCM).
Common Causes of P0697 2014 Chevrolet Silverado
- Faulty 5-Volt Reference Circuit: The most common cause of the P0697 code is a malfunction in the 5-volt reference 3 circuit itself, which can be caused by wiring issues, corrosion, or a short circuit.
- Faulty Sensor: A faulty sensor connected to the 5-volt reference 3 circuit, such as a throttle position sensor or mass airflow sensor, can trigger this code.
- ECM/PCM Malfunction: A malfunction in the engine control module or powertrain control module can also lead to the P0697 code being triggered.
- Electrical Issues: Any electrical problems, such as a blown fuse or a loose connection, within the 5-volt reference 3 circuit can cause this code to appear.
Symptoms of P0697 2014 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P0697 code is the illumination of the check engine light on the vehicle's dashboard.
- Erratic Sensor Readings: The vehicle may experience erratic sensor readings, leading to issues with fuel delivery, ignition timing, and other engine functions.
- Engine Misfires: The engine may misfire or hesitate during acceleration, resulting in a rough running engine.
- Loss of Power: The vehicle may experience a loss of power or reduced performance due to incorrect sensor data being sent to the ECM or PCM.
How to Fix P0697 2014 Chevrolet Silverado
- Diagnose the Issue: Use a diagnostic scanner to retrieve the specific trouble code (P0697) and perform a thorough inspection of the 5-volt reference 3 circuit to identify the root cause of the problem.
- Check Wiring and Connections: Inspect the wiring harness and connections related to the 5-volt reference 3 circuit for any signs of damage, corrosion, or loose connections. Repair or replace any faulty components as needed.
- Test Sensors: Test the sensors connected to the 5-volt reference 3 circuit, such as the throttle position sensor or mass airflow sensor, to ensure they are functioning correctly. Replace any faulty sensors.
- Check ECM/PCM: If all other components check out, inspect the engine control module or powertrain control module for any signs of malfunction. Replace or reprogram the ECM/PCM if necessary.
- Clear Codes and Test Drive: Clear the trouble codes from the vehicle's computer using a diagnostic scanner and take the vehicle for a test drive to ensure the issue has been resolved.
Cost to Fix P0697 2014 Chevrolet Silverado
The typical repair costs for addressing a P0697 code in a 2014 Chevrolet Silverado can range from $150 to $500, depending on the specific cause of the issue and the cost of parts and labor. It's important to note that the 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, but rates may be higher in metropolitan areas or at dealerships, while independent shops often charge less. It is recommended to check with local shops for a more accurate estimate before proceeding with the repair.
