how to fix P0700 code in my Toyota Camry Seventh Generation (2012-2017)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the parking brake engaged.
• Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

• Tools Required: Dipstick, funnel
• Remove the transmission dipstick and check the fluid level and condition.
• If low, add the appropriate type of transmission fluid (Toyota Type T-IV).
• If the fluid is dark or has a burnt smell, consider a fluid change.

3. Inspect Wiring and Connectors

• Tools Required: Multimeter, dielectric grease
• Remove the cover for the transmission control module.
• Visually inspect all wiring harnesses and connectors for damage.
• Use a multimeter to check continuity and voltage at the connectors.
• Clean any corrosion from connectors and apply dielectric grease before reassembly.

4. Test and Replace TCM (if necessary)

• Tools Required: Multimeter, socket set
• Test the TCM using a multimeter to ensure it receives the correct voltage and signals.
• If the TCM is faulty, remove it by unscrewing the mounting bolts and disconnecting the wiring harness.
• Install the new TCM by connecting the harness and securing it with bolts.

5. Reset Error Codes

• Tools Required: OBD-II scanner
• Reconnect the battery and use an OBD-II scanner to clear the P0700 code.
• Start the vehicle and observe if the check engine light returns.
