How to Fix Error Code P0713

  1. Check Transmission Fluid Level and Condition

    Use caution – transmission fluid can be hot. Let engine cool if necessary.

  2. Inspect Wiring and Connector

  3. Test the TFT Sensor Resistance

    Ensure ignition is off and disconnect the sensor before testing.

  4. Check Voltage at Sensor Connector

    Be careful not to short pins. Use proper probe leads.

  5. Replace the Transmission Fluid Temperature Sensor

    Double-check transmission fluid type and capacity. Overfilling can cause damage.

  6. Clear Codes and Test Drive

    If code reappears, further diagnosis may be needed – e.g., internal transmission problem or PCM fault.

When to Call a Professional

If fluid is burnt or contains metal shavings, if the transmission is slipping or has no reverse, or if the code returns after replacing the sensor, have a professional transmission shop diagnose internal damage.

Frequently Asked Questions

Can I drive with error code P0713?
You can drive short distances, but prolonged driving may cause transmission overheating and damage. It's best to diagnose and fix soon.
What is the transmission fluid temperature sensor?
It's a sensor that monitors the temperature of the transmission fluid and sends data to the PCM to control shift patterns and torque converter lockup.
How much does it cost to fix P0713?
If DIY, a sensor costs $20-$80. Professional repair ranges $150-$400 for sensor replacement. If internal transmission damage, costs can exceed $1500.
What other codes are related to P0713?
P0710, P0711, P0712, and P0714 are also related to the transmission fluid temperature sensor circuit.
Can a bad TFT sensor cause transmission slipping?
It can contribute to erratic shifting or delayed engagement, but direct slipping usually indicates mechanical wear.
