how to fix transmission codes on Toyota Camry XV50 (2012-2017) P0700

Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, multimeter, torque wrench, fluid catch pan, and new transmission fluid.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to ensure safety while working with electrical components.

2. Address Transmission Fluid Issues

• Fluid Level Check

  • Remove the transmission dipstick and wipe it clean.
  • Reinsert and remove it again to check the fluid level. Add fluid if necessary, using the recommended type (Toyota ATF WS).

• Fluid Change (if needed)

  • Place a fluid catch pan under the transmission.
  • Remove the transmission pan bolts carefully and lower the pan to drain the old fluid.
  • Clean the pan and replace the filter if applicable.
  • Reinstall the pan with new gasket and torque bolts to manufacturer specifications.
  • Fill with new transmission fluid through the dipstick tube.

3. Inspect and Repair Electrical Connections

• Wiring and Connector Inspection
  • Locate the transmission control module and visually inspect for any signs of damage.
  • Disconnect the connector and clean it with electrical contact cleaner.
  • Reconnect and ensure all connections are secure.

4. Replace Faulty Components

• If the transmission fluid temperature sensor was faulty during testing:
  • Disconnect the battery again.
  • Locate the sensor, remove its connector, and unscrew it using the appropriate socket.
  • Install the new sensor, ensuring it is torqued to specifications.
  • Reconnect all components and the battery.

5. Reprogram Transmission Control Module (if necessary)

• If the TCM requires reprogramming, connect the OBD-II scanner and follow the instructions to update the software according to the manufacturer’s guidelines.
