Code P0713 Honda Description

The P0713 code for Honda vehicles indicates a problem with the transmission fluid temperature sensor, specifically an open circuit. This sensor is responsible for monitoring the temperature of the transmission fluid and providing this information to the vehicle's engine control module (ECM). The ECM uses this data to adjust various aspects of the transmission's operation, such as shift points and torque converter lockup.

  4. ECM Malfunction: A malfunction in the engine control module can prevent it from receiving accurate data from the sensor.
  5. Fluid Contamination: Contaminated transmission fluid can damage the sensor and lead to an open circuit.

Symptoms of P0713 Honda

  1. Check Engine Light: The most common symptom associated with a P0713 code is the illumination of the check engine light on the dashboard.
  2. Erratic Shifting: The transmission may experience erratic shifting behavior, such as harsh or delayed shifts.
  3. Overheating: The transmission may overheat due to the lack of accurate temperature data being provided by the sensor.
  4. Reduced Fuel Efficiency: A malfunctioning transmission fluid temperature sensor can lead to decreased fuel efficiency as the transmission may not be operating optimally.
  5. Transmission Slipping: The transmission may slip between gears, causing a loss of power and acceleration.

How to Fix P0713 Honda

  1. Diagnose the Issue: Use a scan tool to retrieve the trouble code and perform a visual inspection of the sensor and wiring.
  2. Replace the Sensor: If the sensor is found to be faulty, replace it with a new one following the manufacturer's instructions.
  3. Check Wiring: Inspect the wiring harness for any breaks, shorts, or damage, and repair or replace as necessary.
  4. Clear Codes: Clear the trouble codes from the ECM using the scan tool and perform a test drive to ensure the issue has been resolved.
  5. Monitor: Keep an eye on the transmission fluid temperature readings to verify that the new sensor is functioning correctly.

Cost to Fix P0713 Honda

The cost of repairing a P0713 code on a Honda vehicle can vary depending on the specific model and year, as well as the labor rates in your area. In general, the price of a new transmission fluid temperature sensor ranges from $50 to $150, while the labor costs for the repair can range from $100 to $300.
