Code P0712 GMC Description
The P0712 GMC trouble code indicates that there is an issue with the transmission fluid temperature sensor circuit, specifically that the voltage is too low. The transmission fluid temperature sensor is responsible for monitoring the temperature of the transmission fluid and sending this information to the vehicle's engine control module (ECM). This data is crucial for the ECM to make adjustments to the transmission operation, such as shifting points and torque converter lockup.
Common Causes of P0712 GMC
- Faulty transmission fluid temperature sensor
- Damaged wiring or connectors in the sensor circuit
- Malfunctioning ECM
- Low transmission fluid level or poor quality fluid
- Overheating of the transmission system
Symptoms of P0712 GMC
- Check engine light illuminated on the dashboard
- Erratic shifting behavior, such as delayed or harsh shifts
- Transmission slipping or overheating
- Decreased fuel efficiency
- Transmission may go into limp mode to protect itself from damage
How to Fix P0712 GMC
- Begin by using a diagnostic scan tool to retrieve the trouble code and confirm the issue with the transmission fluid temperature sensor circuit.
- Inspect the wiring and connectors in the sensor circuit for any damage or corrosion. Repair or replace any damaged components as needed.
- Test the transmission fluid temperature sensor using a multimeter to determine if it is functioning properly. Replace the sensor if it is faulty.
- Clear the trouble code from the ECM's memory using the diagnostic scan tool and test drive the vehicle to ensure that the issue has been resolved.
- If the problem persists, further diagnostics may be required to pinpoint the exact cause of the low voltage in the transmission fluid temperature sensor circuit.
Cost to Fix P0712 GMC
The typical repair costs for addressing a P0712 GMC trouble code can range from $150 to $400, depending on the specific cause of the issue and the cost of parts and labor. It is important to note that diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It is advisable to obtain quotes from multiple repair shops to get a more accurate estimate for the repair.
