Learn how to diagnose and fix P0715 code related to the Transmission Fluid Temperature sensor in Tesla Outback. Step-by-step guide included.

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Inspect Wiring and Connectors

• Tools Required: Wire stripper, multimeter, electrical connector cleaner
• Remove the undercarriage cover if necessary to access the sensor.
• Visually inspect the wiring harness and connectors for any signs of wear, damage, or corrosion.
• Clean the connectors with electrical connector cleaner before reassembling.

3. Replace Transmission Fluid Temperature Sensor

• Tools Required: Socket set, torque wrench, transmission fluid catch pan
• Locate the Transmission Fluid Temperature sensor on the transmission.
• Disconnect the electrical connector from the sensor.
• Using a socket wrench, carefully unscrew the old sensor from the transmission.
• Install the new sensor by threading it into place, ensuring to use the manufacturer’s specified torque (typically around 15-20 ft-lbs).
• Reconnect the electrical connector firmly.

4. Refill Transmission Fluid (if necessary)

• Tools Required: Funnel, transmission fluid dipstick or fill port
• If fluid was lost during the sensor replacement, refill the transmission with the appropriate type of fluid as specified in the owner’s manual.
• Check the fluid level using the dipstick or fill port, ensuring it is at the correct level.

5. Reconnect Battery and Test

• Reconnect the battery terminals securely.
• Start the engine and let it idle for a few minutes.
