P0692 2018 Chevrolet Silverado Code - Cooling Fan Speed Output Circuit High Voltage
Quick Answer
The P0692 diagnostic trouble code (DTC) for a 2018 Chevrolet Silverado indicates a problem with the cooling fan speed output circuit registering high voltage. Common causes include Faulty cooling fan motor: A malfunctioning cooling fan motor can draw excessive voltage, causing the high voltage in the cooling fan speed output circuit, Wiring issues: Damaged or corroded wiring in the cooling fan speed output circuit can lead to high voltage readings, Faulty cooling fan relay: A defective cooling fan relay can cause the cooling fan to receive an incorrect voltage signal, resulting in high voltage in the output 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 P0692 2018 Chevrolet Silverado Description
The P0692 diagnostic trouble code (DTC) for a 2018 Chevrolet Silverado indicates a problem with the cooling fan speed output circuit registering high voltage. This code is typically triggered when the Engine Control Module (ECM) detects a voltage signal from the cooling fan speed output circuit that is higher than the specified range. The cooling fan is a crucial component of the vehicle's cooling system, responsible for regulating the temperature of the engine by dissipating heat. When the cooling fan speed output circuit is experiencing high voltage, it can lead to issues with the cooling system's performance, potentially causing the engine to overheat.
Common Causes of P0692 2018 Chevrolet Silverado
- Faulty cooling fan motor: A malfunctioning cooling fan motor can draw excessive voltage, causing the high voltage in the cooling fan speed output circuit.
- Wiring issues: Damaged or corroded wiring in the cooling fan speed output circuit can lead to high voltage readings.
- Faulty cooling fan relay: A defective cooling fan relay can cause the cooling fan to receive an incorrect voltage signal, resulting in high voltage in the output circuit.
- ECM malfunction: A malfunctioning Engine Control Module (ECM) can incorrectly interpret voltage signals from the cooling fan speed output circuit, triggering the P0692 code.
- Overheating conditions: Continuous overheating of the engine can also contribute to high voltage in the cooling fan speed output circuit, as the cooling fan may be working harder to regulate the temperature.
Symptoms of P0692 2018 Chevrolet Silverado
- Engine overheating: One of the most common symptoms associated with the P0692 code is engine overheating. The cooling fan plays a crucial role in regulating the engine's temperature, and if the fan is not functioning properly due to high voltage in the output circuit, the engine may overheat.
- Check Engine Light: The illumination of the Check Engine Light on the vehicle's dashboard is another common symptom of the P0692 code. The ECM detects the high voltage in the cooling fan speed output circuit and triggers the warning light to alert the driver to a potential issue.
- Reduced cooling fan operation: The cooling fan may operate at a lower speed or intermittently due to the high voltage in the output circuit, leading to inadequate cooling of the engine.
- Poor air conditioning performance: The vehicle's air conditioning system may not function as efficiently if the cooling fan is not operating at the correct speed, resulting in reduced cooling performance.
- Increased engine temperature gauge readings: The temperature gauge on the vehicle's dashboard may show higher-than-normal readings, indicating that the engine is running hotter than usual due to cooling system issues.
How to Fix P0692 2018 Chevrolet Silverado
- Diagnose the issue: Use a diagnostic scanner to retrieve the DTC and perform a thorough inspection of the cooling fan speed output circuit, cooling fan motor, wiring, and relay to identify the root cause of the high voltage.
- Replace faulty components: If a faulty cooling fan motor, wiring, relay, or ECM is identified as the cause of the high voltage, replace the defective component with a new one to restore proper operation.
- Repair damaged wiring: If damaged or corroded wiring is the issue, repair or replace the affected wiring to ensure a secure connection and prevent future electrical problems.
- Clear the DTC: After completing the repairs, clear the DTC from the ECM's memory using a diagnostic scanner to reset the Check Engine Light and verify that the issue has been resolved.
- Test the cooling system: Test the cooling system by running the engine and monitoring the operation of the cooling fan to ensure that it is functioning correctly and maintaining the engine's temperature within the optimal range.
Cost to Fix P0692 2018 Chevrolet Silverado
The typical repair costs for addressing the P0692 code on a 2018 Chevrolet Silverado can vary depending on the specific cause of the issue and the cost of parts and labor. In general, replacing a faulty cooling fan motor, wiring, relay, or ECM can range from $200 to $800, including parts and labor. However, the total cost may be higher if multiple components need to be replaced or if additional repairs are required. It's important to note that diagnostic time and labor rates at auto repair shops can vary, with hourly rates typically ranging between $80 and $150. Rates may be higher at dealerships or in metropolitan areas, while independent shops often offer more competitive pricing. For a precise estimate, it's recommended to consult with a local auto repair shop.
