P0712 2016 GMC Sierra Code - Transmission Fluid Temperature Sensor Circuit Low Voltage
Quick Answer
The P0712 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates a problem with the Transmission Fluid Temperature Sensor Circuit, specifically detecting low voltage. Common causes include Faulty Sensor: The most common cause of this code is a faulty transmission fluid temperature sensor that is not providing accurate readings to the ECM, Wiring Issues: Damage or corrosion to the wiring harness connecting the sensor to the ECM can disrupt the signal and trigger a low voltage reading, ECM Malfunction: A malfunctioning ECM can also be a potential cause of this code, as it may not be properly interpreting the signal from the sensor. 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 P0712 2016 GMC Sierra Description
The P0712 diagnostic trouble code (DTC) for a 2016 GMC Sierra indicates a problem with the Transmission Fluid Temperature Sensor Circuit, specifically detecting low voltage. The transmission fluid temperature sensor plays a crucial role in monitoring the temperature of the transmission fluid, which is essential for ensuring optimal performance and longevity of the transmission system. When the sensor detects low voltage, it means that the signal being sent to the engine control module (ECM) is below the expected range, indicating a potential issue with the sensor itself or the circuitry.
Common Causes of P0712 2016 GMC Sierra
- Faulty Sensor: The most common cause of this code is a faulty transmission fluid temperature sensor that is not providing accurate readings to the ECM.
- Wiring Issues: Damage or corrosion to the wiring harness connecting the sensor to the ECM can disrupt the signal and trigger a low voltage reading.
- ECM Malfunction: A malfunctioning ECM can also be a potential cause of this code, as it may not be properly interpreting the signal from the sensor.
- Fluid Contamination: Contaminated transmission fluid can affect the sensor's ability to accurately measure temperature, leading to erroneous readings.
- Poor Electrical Ground: A poor electrical ground connection can also result in low voltage readings from the sensor, causing the code to be triggered.
Symptoms of P0712 2016 GMC Sierra
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Erratic Shifting: The transmission may exhibit erratic shifting behavior, such as harsh or delayed shifts, due to inaccurate temperature readings.
- Poor Fuel Efficiency: A malfunctioning transmission fluid temperature sensor can lead to decreased fuel efficiency as the transmission may not operate at optimal temperatures.
- Overheating: In severe cases, the transmission may overheat due to the lack of accurate temperature monitoring, potentially causing damage to internal components.
How to Fix P0712 2016 GMC Sierra
- Diagnose the Issue: Begin by using a scan tool to retrieve the DTC and verify the low voltage reading from the transmission fluid temperature sensor.
- Inspect Wiring and Connections: Check the wiring harness for any damage, corrosion, or loose connections that may be affecting the sensor's signal.
- Test the Sensor: Test the transmission fluid temperature sensor using a multimeter to determine if it is providing accurate readings.
- Replace the Sensor: If the sensor is found to be faulty, replace it with a new one and ensure proper installation.
- Clear Codes and Test Drive: Clear the DTC from the ECM memory, then test drive the vehicle to verify that the issue has been resolved and the code does not return.
Cost to Fix P0712 2016 GMC Sierra
The typical repair costs for addressing a P0712 code on a 2016 GMC Sierra can vary depending on the specific cause of the issue. In general, the cost of replacing a transmission fluid temperature sensor can range from $100 to $200 for the part itself. Labor costs can add an additional $100 to $200, depending on the shop's hourly rates and the complexity of the repair. Overall, the total cost for parts and labor for this repair is likely to fall in the range of $200 to $400. It's important to note that these estimates are rough averages and actual costs may vary based on factors such as location, vehicle make and model, and the specific repair shop. It's recommended to obtain quotes from local auto repair shops to get a more accurate estimate for this repair.
