Code P0117 2014 Chevrolet Silverado Description
The P0117 code for a 2014 Chevrolet Silverado indicates a problem with the Engine Coolant Temperature (ECT) Circuit, specifically a low input signal. The ECT sensor is responsible for monitoring the temperature of the engine coolant, which is crucial for the engine's performance and efficiency. When the ECT sensor detects a low input signal, it means that the engine coolant temperature is below the expected range. This could be due to a faulty sensor, wiring issues, or problems with the engine coolant itself.
Common Causes of P0117 2014 Chevrolet Silverado
- Faulty ECT Sensor: The ECT sensor may be malfunctioning or sending incorrect signals to the engine control module.
- Damaged Wiring: Wiring issues, such as frayed or corroded wires, can disrupt the ECT circuit and cause a low input signal.
- Low Coolant Levels: Insufficient coolant in the system can lead to inaccurate temperature readings from the ECT sensor.
- Air Pockets in Cooling System: Air pockets trapped in the cooling system can interfere with the ECT sensor's ability to measure coolant temperature accurately.
- Coolant Leak: A coolant leak can result in low coolant levels and affect the ECT sensor's performance.
Symptoms of P0117 2014 Chevrolet Silverado
- Check Engine Light: The most common symptom associated with the P0117 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Poor Fuel Economy: A faulty ECT sensor can cause the engine to run rich or lean, leading to decreased fuel efficiency.
- Engine Overheating: If the ECT sensor provides inaccurate readings, it can prevent the cooling system from functioning correctly, resulting in engine overheating.
- Rough Idling: Incorrect coolant temperature readings can disrupt the engine's idle speed control, causing rough idling or stalling.
- Hesitation During Acceleration: The engine may hesitate or lack power during acceleration due to incorrect fuel mixture and timing adjustments.
How to Fix P0117 2014 Chevrolet Silverado
- Diagnostic: The first step in resolving the P0117 code is to perform a thorough diagnostic check to pinpoint the exact cause of the low input signal.
- ECT Sensor Replacement: If the ECT sensor is faulty, it will need to be replaced with a new one to restore accurate temperature readings.
- Wiring Inspection: Inspect the wiring and connectors in the ECT circuit for any damage or corrosion and repair or replace as needed.
- Coolant System Check: Verify the coolant levels and top up if necessary, ensuring there are no leaks or air pockets in the cooling system.
- Clearing Codes: After completing the repairs, clear the diagnostic trouble codes stored in the vehicle's computer to reset the Check Engine Light.
Cost to Fix P0117 2014 Chevrolet Silverado
The typical repair costs for addressing a P0117 code on a 2014 Chevrolet Silverado can vary depending on the specific cause of the issue. Replacing a faulty ECT sensor can cost between $50 to $150 for the part, with additional labor charges ranging from $80 to $150 per hour. Wiring repairs or coolant system checks may incur additional costs, bringing the total repair estimate to around $150 to $300. It's essential to consider the specific diagnosis time and labor rates at auto repair shops, which can vary based on location, vehicle make and model, and engine type. Checking local rates and obtaining multiple quotes can help in getting a more accurate estimate for the repair costs.

Frequently Asked Questions about P0117 2014 Chevrolet Silverado Code
What does the OBDII code P0117 mean for a 2014 Chevrolet Silverado?
P0117 indicates that the Engine Control Module (ECM) has detected a low voltage input from the Engine Coolant Temperature (ECT) sensor, suggesting an issue with the sensor or its circuit.
What are the common symptoms of P0117 in a 2014 Chevrolet Silverado?
Symptoms may include engine overheating, poor fuel economy, difficulty starting the engine, erratic temperature gauge readings, or the check engine light being illuminated.
What causes the P0117 code to appear on a 2014 Chevrolet Silverado?
Common causes include a faulty ECT sensor, damaged wiring or connectors in the ECT circuit, a short or open circuit, or an issue with the ECM itself.
Can driving with the P0117 code damage my 2014 Chevrolet Silverado?
Yes, driving with this code can lead to engine overheating, which may cause severe damage to the engine components if not addressed promptly.
How can I diagnose the P0117 code on my 2014 Chevrolet Silverado?
Start by inspecting the ECT sensor, its wiring, and connectors for damage. Check for corrosion, loose connections, or breaks in the wiring. Use a multimeter to test the sensor's resistance and voltage readings.
How do I fix the P0117 code on a 2014 Chevrolet Silverado?
Repairs may include replacing the ECT sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or reprogramming the ECM if necessary.
