P06AE 2014 Chevrolet Silverado Code - Control Module Power Up Temperature Sensor Circuit High Voltage
Quick Answer
The P06AE code indicates that the Engine Control Module (ECM) has detected a high voltage condition in the temperature sensor circuit responsible for monitoring the power-up temperature of the control module itself. Common causes include Faulty Temperature Sensor: The sensor itself may be malfunctioning, producing erroneous high voltage readings, Wiring Issues: Damaged or frayed wiring in the temperature sensor circuit can lead to high voltage conditions, Corroded Connectors: Corrosion at the sensor or ECM connectors can disrupt proper electrical flow, causing high voltage signals. 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 2014 Chevrolet Silverado Description
The P06AE code indicates that the Engine Control Module (ECM) has detected a high voltage condition in the temperature sensor circuit responsible for monitoring the power-up temperature of the control module itself. This sensor is crucial for the ECM to determine the optimal operating conditions for the engine and other related systems. When the ECM identifies a high voltage reading from this sensor, it can lead to incorrect calculations regarding engine performance, fuel mixture, and ignition timing, potentially resulting in poor engine performance, increased emissions, and reduced fuel efficiency.
Common Causes of P06AE 2014 Chevrolet Silverado
- Faulty Temperature Sensor: The sensor itself may be malfunctioning, producing erroneous high voltage readings.
- Wiring Issues: Damaged or frayed wiring in the temperature sensor circuit can lead to high voltage conditions.
- Corroded Connectors: Corrosion at the sensor or ECM connectors can disrupt proper electrical flow, causing high voltage signals.
- ECM Malfunction: A failure within the ECM itself can lead to incorrect readings and trigger the P06AE code.
- Short Circuits: A short circuit in the wiring harness can cause excessive voltage to be sent to the sensor.
Symptoms of P06AE 2014 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 lack of power, rough idling, or stalling, particularly during acceleration.
- Increased Fuel Consumption: A malfunctioning sensor can lead to incorrect fuel mixture calculations, resulting in lower fuel efficiency.
- Erratic Shifting: If the vehicle has an automatic transmission, shifting may become harsh or unpredictable due to incorrect data being sent to the transmission control module.
- Overheating Issues: In some cases, the vehicle may experience overheating due to improper engine temperature management.
How to Fix P06AE 2014 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 further insight into the issue.
- Visual Inspection: Conduct a thorough visual inspection of the wiring and connectors associated with the temperature sensor for signs of damage, corrosion, or loose connections.
- Sensor Testing: Test the temperature sensor using a multimeter to check its resistance and voltage output against manufacturer specifications.
- Repair or Replace: Based on the findings, repair any damaged wiring or connectors. If the sensor is faulty, replace it with a new one.
- ECM Reprogramming: After repairs, it may be necessary to clear the codes and reprogram the ECM to ensure it recognizes the new sensor readings.
Cost to Fix P06AE 2014 Chevrolet Silverado
The typical repair costs for addressing the P06AE code can vary widely based on the specific diagnosis and repairs needed. On average, you might expect to pay between $150 and $500 for parts and labor. This estimate includes the cost of a new temperature sensor, wiring repairs, and labor charges. Diagnosis time can take anywhere from 1 to 2 hours, depending on the complexity of the issue. Labor rates at auto repair shops generally range from $80 to $150 per hour; however, rates may be higher at dealerships or in metropolitan areas, while independent shops may offer lower rates. It is advisable to check local rates for a more precise estimate tailored to your location and vehicle specifics.
