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

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery (negative terminal) to prevent electrical shorts.
• Ensure the vehicle is on a level surface and securely raised on jack stands if needed.

2. Inspect and Replace Transmission Fluid

• Sub-steps:
  1. Locate the transmission dipstick and remove it.
  2. Using a funnel, add the recommended transmission fluid type (typically ATF WS for Toyota).
  3. Check fluid level with the engine running and transmission in park.
• Tools Required: Funnel, transmission fluid, dipstick.

3. Check and Repair Wiring/Connectors

• Sub-steps:
  1. Visually inspect the wiring harness for any frays, breaks, or corrosion.
  2. Clean any corroded connections with electrical contact cleaner.
  3. If damaged wires are found, repair or replace as necessary.
• Tools Required: Electrical contact cleaner, wire strippers/crimpers.

4. Test Transmission Range Sensor

• Sub-steps:
  1. Remove the connector from the transmission range sensor.
  2. Using a multimeter, check for continuity across the sensor terminals while moving the gear selector.
  3. If no continuity is present, replace the transmission range sensor.
• Tools Required: Multimeter, socket set.

5. Replace Transmission Control Module (if necessary)

• Sub-steps:
  1. Locate the TCM, usually found near the transmission or under the dashboard.
  2. Disconnect the TCM connectors carefully.
  3. Remove the TCM using the appropriate socket size.
  4. Install the new TCM and reconnect the connectors.
• Tools Required: Socket set, torque wrench (if specified).
