how to fix P0700 code in Toyota Camry Eighth Generation (2018-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery negative terminal to prevent electrical shock.

2. Check Transmission Fluid

• Tools Required: Transmission fluid dipstick, funnel, new transmission fluid (if needed)
• Remove the transmission dipstick and check the fluid level.
• If low, add the recommended type of transmission fluid (Toyota ATF WS) until it reaches the proper level.

3. Inspect Wiring and Connectors

• Tools Required: Multimeter, visual inspection tools
• Inspect the wiring harness for any frayed wires or loose connections.
• Use a multimeter to test the voltage at the TCM connector; ensure it matches the specifications in the service manual.
• Repair or replace damaged wiring as necessary.

4. Replace Transmission Control Module (if necessary)

• Tools Required: Socket set, torque wrench
• Remove the bolts securing the TCM using the socket set.
• Disconnect the electrical connectors from the TCM.
• Install the new TCM by reversing the removal process. Secure it with the specified torque values (consult the vehicle service manual for exact specifications).

5. Clear Codes and Test Drive

• Tools Required: OBD-II scanner
• Reconnect the battery and use the OBD-II scanner to clear the P0700 code from the system.
• Perform a test drive to ensure the transmission operates smoothly and the check engine light does not reappear.
