• Use a multimeter to test for continuity in the wiring.
• Repair or replace any damaged wires or connectors.

4. Test Transmission Range Sensor

• Tools Required: Multimeter, basic hand tools.
• Locate the transmission range sensor, typically mounted on the transmission.
• Disconnect the sensor connector and measure resistance according to specifications.
• If the readings are out of range, replace the sensor.

5. Reconnect Battery and Clear Codes

• Reconnect the vehicle's battery.
• Use the OBD-II scanner to clear the P0700 code and any other transmission-related codes.
• Start the vehicle and ensure the check engine light does not reappear.
