P0712 Mitsubishi Code - Transmission Fluid Temperature Sensor Low Input
Quick Answer
The P0712 code for Mitsubishi vehicles indicates a Transmission Fluid Temperature Sensor Low Input. Common causes include Faulty Transmission Fluid Temperature Sensor: The sensor itself may be faulty and not providing accurate temperature readings, Wiring or Connector Issues: Damage to the wiring or connectors in the sensor circuit can interrupt the signal between the sensor and the PCM, PCM Malfunction: A malfunctioning PCM can also cause the transmission fluid temperature sensor low input code to be triggered. 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 Mitsubishi Description
The P0712 code for Mitsubishi vehicles indicates a Transmission Fluid Temperature Sensor Low Input. This means that the powertrain control module (PCM) has detected a lower than normal voltage signal from the transmission fluid temperature sensor. The transmission fluid temperature sensor is responsible for monitoring the temperature of the transmission fluid, which is crucial for the proper operation of the transmission system.
Common Causes of P0712 Mitsubishi
- Faulty Transmission Fluid Temperature Sensor: The sensor itself may be faulty and not providing accurate temperature readings.
- Wiring or Connector Issues: Damage to the wiring or connectors in the sensor circuit can interrupt the signal between the sensor and the PCM.
- PCM Malfunction: A malfunctioning PCM can also cause the transmission fluid temperature sensor low input code to be triggered.
- Low Transmission Fluid Level: A low transmission fluid level can also impact the accuracy of the temperature sensor readings.
- Extreme Temperature Conditions: Extreme temperature conditions, such as extreme heat or cold, can also affect the sensor's performance and trigger the P0712 code.
Symptoms of P0712 Mitsubishi
- Illuminated Check Engine Light: The most common symptom associated with the P0712 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Erratic Shifting: The transmission may experience erratic shifting behavior, such as delayed or harsh shifts, due to inaccurate temperature readings.
- Poor Fuel Efficiency: Incorrect transmission fluid temperature readings can result in poor fuel efficiency as the PCM may not optimize transmission functions accordingly.
- Transmission Overheating: In severe cases, the transmission fluid temperature sensor issue can lead to transmission overheating, which can cause further damage to internal components.
How to Fix P0712 Mitsubishi
- Diagnose the Issue: Use a scan tool to retrieve the trouble code and perform a thorough inspection of the transmission fluid temperature sensor, wiring, and connectors.
- Replace the Transmission Fluid Temperature Sensor: If the sensor is faulty, replace it with a new one to ensure accurate temperature readings.
- Repair Wiring or Connectors: If there are any damaged wires or connectors in the sensor circuit, repair or replace them as needed.
- Clear the Trouble Code: After the repair is complete, clear the trouble code from the PCM memory using a scan tool.
- Test Drive: Take the vehicle for a test drive to ensure that the transmission is operating correctly and there are no further issues with the sensor.
Cost to Fix P0712 Mitsubishi
The typical repair costs for addressing a Transmission Fluid Temperature Sensor Low Input code can range from $150 to $300, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. Keep in mind that most auto repair shops charge between $80 and $150 per hour for labor, but rates may be higher in metropolitan areas or at dealerships and lower at independent shops. It is advisable to check local rates to get a more accurate estimate for this repair.
