This summary uses the existing diagnostic information shown in full below.
Your car has a sensor that checks how hot the transmission fluid is. This code means the sensor is saying the fluid is too cold, which might not be right.
The transmission fluid temperature sensor is reporting a lower than expected voltage, indicating a possible issue with the sensor or its circuit.
The P0712 code is triggered when the Powertrain Control Module (PCM) detects a low voltage signal from the transmission fluid temperature sensor. This sensor monitors the temperature of the transmission fluid, which is crucial for optimal transmission performance. A low voltage signal usually indicates that the sensor is reading a temperature that is lower than the expected range.
• Check Engine Light is on
• Transmission may shift harshly or erratically
• Poor fuel economy
• Transmission overheating
• Vehicle may go into limp mode
• Faulty transmission fluid temperature sensor
• Wiring issues such as shorts or open circuits
• Poor electrical connections
• Low transmission fluid level
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the transmission fluid level and condition.
• Check the wiring and connectors for damage or corrosion.
• Test the transmission fluid temperature sensor with a multimeter.
• Check the PCM for any additional codes or faults.
• Replace the transmission fluid temperature sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Refill or replace transmission fluid if necessary.
• Reprogram or replace the PCM if needed.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check and maintain transmission fluid levels.
• Inspect wiring and connectors for wear and tear.
• Schedule regular vehicle maintenance.
Sensor Issue
• Do not ignore the Check Engine Light.
• Get the vehicle checked by a professional if you notice transmission issues.
• Regular maintenance can prevent such issues.
Check your vehicle's warranty coverage for sensor-related repairs.
This code has been reported in vehicles with high mileage or those that have not had regular transmission maintenance.
Moderate – Should be addressed soon to prevent transmission damage.
Driving with this issue may cause further damage to the transmission, potentially leading to costly repairs.
• Vehicle at operating temperature
• Transmission in gear
The transmission fluid temperature sensor is typically located inside the transmission or in the transmission oil pan.
Q: Can I drive with a P0712 code?
A: It's not recommended to drive for long periods with this code as it can lead to transmission damage.
Q: How can I prevent a P0712 code?
A: Regular maintenance and checking transmission fluid levels can help prevent this issue.
