how to fix P0700 transmission code in Honda Accord 9th Generation (2013-2017)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Raise the vehicle using a jack and secure it with jack stands.

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Locate the transmission dipstick or fill plug and remove it.
  2. Use a fluid pump to extract old transmission fluid from the transmission pan.
  3. Inspect the fluid; it should be bright red and free of debris. If it is dark or has a burnt smell, replace it.
  4. Refill with Honda ATF DW-1 transmission fluid using a funnel until it reaches the proper level.

3. Inspect and Replace Faulty Sensors

• Sub-steps:
  1. Locate the transmission fluid temperature sensor and disconnect the wiring harness.
  2. Remove the sensor using a socket wrench.
  3. Install the new sensor, tightening it to the manufacturer's torque specification (typically around 8-10 Nm).
  4. Reconnect the wiring harness.

4. Repair or Replace Wiring and Connectors

• Sub-steps:
  1. Visually inspect the wiring harness for fraying, corrosion, or damage.
  2. Repair any damaged wiring with electrical tape or replace the entire harness if necessary.
  3. Ensure all connectors are clean and securely fastened.

5. Test Transmission Control Solenoids

• Sub-steps:
  1. Remove the transmission pan to access the solenoids (may require draining fluid).
  2. Disconnect the electrical connectors from the solenoids.
  3. Use a multimeter to test each solenoid according to manufacturer specifications (usually between 20-30 ohms).
  4. Replace any faulty solenoids and reassemble the transmission pan with a new gasket.
