DTC P0713 Transmission Fluid Temperature Sensor Circuit High Input

DTC P0713 indicates an issue within the Transmission Fluid Temperature Sensor Circuit, signaling a high input signal to the Powertrain Control Module (PCM). This code triggers when the signal received from the transmission fluid temperature sensor exceeds the expected threshold.

1. What does P0713 code mean?

DTC P0713 specifically points to a problem in the Transmission Fluid Temperature Sensor Circuit, signaling a high input signal to the PCM. It indicates that the signal received from the sensor is above the anticipated threshold.

2. What are the causes of DTC P0713?

Potential causes of DTC P0713 may include:

  • Faulty Temperature Sensor: A malfunctioning or failed transmission fluid temperature sensor.
  • Wiring or Connector Issues: Damaged, corroded, or shorted wiring and connectors associated with the transmission fluid temperature sensor.
  • Sensor Circuit Malfunction: Issues within the transmission fluid temperature sensor circuit, such as short circuits or a failed sensor.

3. What are the symptoms of DTC P0713?

Symptoms associated with DTC P0713 might include:

  • Check Engine Light: Illumination of the Check Engine Light on the dashboard.
  • Transmission Issues: Irregular shifting patterns, harsh shifting, or the transmission staying in a single gear.
  • Temperature Readings: Incorrect or misleading readings regarding the transmission fluid temperature, usually indicating high temperatures consistently.

4. How to diagnose DTC P0713?

Diagnosing DTC P0713 typically involves these steps:

  • OBD-II Scan: Use an OBD-II scanner to retrieve the trouble code and any accompanying codes.
  • Visual Inspection: Inspect the transmission fluid temperature sensor and its wiring for damage, corrosion, or short circuits.
  • Sensor Testing: Verify the transmission fluid temperature sensor’s resistance and voltage to ensure it’s within specified parameters.
  • Circuit Testing: Test the sensor’s power supply, ground, and signal circuit for integrity.

5. How to fix DTC P0713 problem?

To resolve DTC P0713, consider the following steps:

  • Repair or Replace Faulty Components: Address any damaged wiring, connectors, or replace a malfunctioning transmission fluid temperature sensor identified during inspection.
  • Clear Codes: After rectifying the issue, use an OBD-II scanner to clear the trouble codes and reset the Check Engine Light.
  • Professional Assistance: Seek help from a certified mechanic for complex sensor or wiring issues or for further diagnosis and repair.


DTC P0713, indicating a high input signal from the Transmission Fluid Temperature Sensor Circuit, requires a systematic approach to identify and rectify issues within the sensor or its associated circuitry for accurate temperature readings and proper transmission functionality.
