P0808 2015 Chevrolet Silverado Code - Clutch Pedal Position Sensor Circuit High Voltage
Quick Answer
The diagnostic trouble code P0808 in a 2015 Chevrolet Silverado indicates a problem with the clutch pedal position sensor circuit registering high voltage. Common causes include Faulty Clutch Pedal Position Sensor: The sensor itself may be malfunctioning, sending incorrect voltage signals to the ECM, Wiring Issues: Damaged or corroded wiring connections between the sensor and the ECM can disrupt the signal transmission, ECM Malfunction: A problem with the engine control module can also cause high voltage readings from the sensor 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 P0808 2015 Chevrolet Silverado Description
The diagnostic trouble code P0808 in a 2015 Chevrolet Silverado indicates a problem with the clutch pedal position sensor circuit registering high voltage. The clutch pedal position sensor is a crucial component that monitors the position of the clutch pedal and sends this information to the engine control module (ECM). The ECM uses this data to adjust various parameters such as engine speed, fuel injection, and ignition timing.
Common Causes of P0808 2015 Chevrolet Silverado
- Faulty Clutch Pedal Position Sensor: The sensor itself may be malfunctioning, sending incorrect voltage signals to the ECM.
- Wiring Issues: Damaged or corroded wiring connections between the sensor and the ECM can disrupt the signal transmission.
- ECM Malfunction: A problem with the engine control module can also cause high voltage readings from the sensor circuit.
- Poor Ground Connection: A weak or poor ground connection can lead to voltage spikes in the sensor circuit.
- Mechanical Damage: Physical damage to the clutch pedal position sensor or its components can result in high voltage readings.
Symptoms of P0808 2015 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with a P0808 code is the illumination of the check engine light on the dashboard.
- Difficulty Shifting Gears: A faulty clutch pedal position sensor can cause issues with shifting gears smoothly, leading to grinding or resistance when changing gears.
- Engine Stalling: The incorrect input from the sensor can result in engine stalling, especially when engaging or disengaging the clutch.
- Reduced Fuel Efficiency: The ECM may not be able to optimize fuel injection based on the faulty sensor data, leading to decreased fuel efficiency.
- Harsh Acceleration: The vehicle may exhibit jerky or harsh acceleration due to inaccurate sensor readings affecting engine performance.
How to Fix P0808 2015 Chevrolet Silverado
- Diagnostic Scan: Use a diagnostic scanner to retrieve the trouble code and pinpoint the exact cause of the issue.
- Check Sensor Wiring: Inspect the wiring harness for any damage, corrosion, or loose connections. Repair or replace as needed.
- Test Sensor Voltage: Test the voltage output of the clutch pedal position sensor to verify if it is within the specified range.
- Replace Sensor: If the sensor is found to be faulty, replace it with a new one and ensure proper installation.
- Clear Codes: After completing the repair, clear the trouble codes from the ECM memory and test drive the vehicle to confirm that the issue has been resolved.
Cost to Fix P0808 2015 Chevrolet Silverado
The cost of repairing a P0808 code in a 2015 Chevrolet Silverado can vary depending on the specific cause of the issue. On average, the parts cost for a new clutch pedal position sensor ranges from $50 to $150. Labor costs at an auto repair shop typically range from $80 to $150 per hour. Therefore, the total repair cost can range from $150 to $400, including parts and labor. It is recommended to consult with a local auto repair shop for a more accurate estimate based on your location and vehicle specifics.
