P06AE 2018 Chevrolet Silverado Code - Control Module Power Up Temperature Sensor Circuit High Voltage
Quick Answer
The P06AE diagnostic trouble code (DTC) indicates a high voltage condition in the Control Module Power Up Temperature Sensor Circuit for a 2018 Chevrolet Silverado. Common causes include Faulty Temperature Sensor: The most common cause is a malfunctioning temperature sensor that provides inaccurate voltage readings, Wiring Issues: Damaged or frayed wiring in the sensor circuit can lead to high voltage signals being sent to the ECM, Connector Problems: Corrosion or loose connections at the sensor or ECM can disrupt the signal and cause high voltage readings. 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 P06AE 2018 Chevrolet Silverado Description
The P06AE diagnostic trouble code (DTC) indicates a high voltage condition in the Control Module Power Up Temperature Sensor Circuit for a 2018 Chevrolet Silverado. This code is triggered when the Engine Control Module (ECM) detects that the voltage level from the temperature sensor is above the expected range. The temperature sensor is crucial for monitoring the temperature of the engine and other critical components, ensuring optimal performance and efficiency.
Common Causes of P06AE 2018 Chevrolet Silverado
- Faulty Temperature Sensor: The most common cause is a malfunctioning temperature sensor that provides inaccurate voltage readings.
- Wiring Issues: Damaged or frayed wiring in the sensor circuit can lead to high voltage signals being sent to the ECM.
- Connector Problems: Corrosion or loose connections at the sensor or ECM can disrupt the signal and cause high voltage readings.
- ECM Malfunction: In rare cases, a fault within the ECM itself can lead to incorrect processing of the sensor's data.
- Environmental Factors: Exposure to extreme temperatures or moisture can affect the sensor's performance and reliability.
Symptoms of P06AE 2018 Chevrolet Silverado
- Check Engine Light: The most immediate symptom is the illumination of the check engine light on the dashboard.
- Poor Engine Performance: Drivers may notice a decrease in engine power, acceleration, or responsiveness.
- Increased Fuel Consumption: A malfunctioning temperature sensor can lead to improper fuel mixture, resulting in lower fuel efficiency.
- Overheating: The engine may overheat due to incorrect temperature readings, leading to potential engine damage.
- Erratic Idling: The vehicle may experience rough or unstable idling, indicating that the ECM is struggling to maintain optimal engine parameters.
How to Fix P06AE 2018 Chevrolet Silverado
- Diagnostic Scan: Begin by using an OBD-II scanner to confirm the P06AE code and check for any additional codes that may provide more context.
- Visual Inspection: Conduct a thorough visual inspection of the temperature sensor, wiring, and connectors for signs of damage, corrosion, or loose connections.
- Sensor Testing: Test the temperature sensor with a multimeter to verify its resistance and voltage output against manufacturer specifications.
- Repair or Replace Components: If the sensor is faulty, replace it. If wiring or connectors are damaged, repair or replace them as necessary to ensure a solid connection.
- Clear Codes and Test Drive: After repairs, clear the DTCs using the scanner and perform a test drive to ensure the check engine light does not reappear and that the vehicle operates normally.
Cost to Fix P06AE 2018 Chevrolet Silverado
The cost to repair a P06AE code can vary widely based on the specific issue and the labor rates in your area. On average, the total cost for parts and labor can range from $150 to $600. A temperature sensor replacement typically costs between $50 and $150 for the part, while labor can range from $100 to $450 depending on the complexity of the repair and the shop's hourly rate.
