What is the P0712 fault number? What is the Transmission Fluid temperature Sensor A Circuit low input error code? How do I fix the P0712 fault code What are the causes and symptoms of the P0712 error code?
What is the P0712 fault code? What does it signify?
A lot of vehicles have a sensor to measure the transmission oil temperature (TFT). This sensor is used by the powertrain control module (PCM), to calculate certain parameters. A code P0712 indicates that the code is valid. “Transmission Fluid Temperature Sensor A Circuit Low Input” .
The TFT sensor is used by your vehicle to determine shift points and transmission pressure. This sensor is located behind the oil pan in the transmission valve body.
The TFT sensor has a negative temperature coefficient (NTC). This means that its internal resistance is proportional to oil temperature. The TFT sensor’s resistance decreases with increasing transmission oil temperatures. However, it increases when the temperature drops. If the PCM detects a voltage signal from a TFT sensor that is significantly lower than the manufacturer’s recommended range, the code P0712 has been set.
P0712 fault codes can be found on vehicles made by Toyota, Ford and Nissan as well as Honda, Nissan, Renault and Hyundai.
What causes the P0712 Fault code?
Below are some reasons to set fault code P0712:
- – Defective transmission fluid temperature (TFT) sensor
- – Broken wires or loose or rusty connectors. Open or short circuit issues
- – Internal mechanical problems with transmissions
- – Use a dirty transmission oil
- – Transmission fluid missing or leaking
- Clogged transmission filter
What are the symptoms for P0712 Malfunction Codes?
These symptoms may be present if you own a vehicle that has the code “P0712”.
- – Illumination at the check engine lights
- – Torque converter clutch malfunction
- – Irregular, harsh or delayed gear changes
- – Gearbox overheating
- – The transmission may emit smoke or other burning odors
- – The vehicle safe mode (Limp Mod) can prevent the transmission from shifting. Also, the vehicle’s speed can be restricted by entering this setting
How to Fix the P0712 Fault Code
The following repairs may be able to resolve the P0712 fault code:
- – Replace the temperature sensor for transmission oil.
- Repair of damaged wires, connectors, or open or short circuit problems in the transmission oil temperature sensor circuit
- – Cleaning the gearbox, and changing the oil
- – Transmission oil leak repair and completion, if necessary
- – Removing the old transmission filter
How serious is the P0712 Fault code?
This code can be categorized as medium-high to severe. This code could indicate a problem with the transmission in certain cases. It is a good idea for you to address this code immediately.
