how to fix P0700 code in Honda CR-V Fifth Generation (2017-2022)

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, fluid catch pan, funnel.
• Ensure the vehicle is parked on a level surface.
• Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Place a fluid catch pan under the transmission pan.
  2. Remove the transmission drain plug and allow old fluid to drain completely.
  3. Inspect the old fluid for metal shavings or burnt odor.
  4. Replace the drain plug and torque it to the manufacturer’s specifications (typically around 25-30 ft-lbs).
  5. Refill the transmission with the appropriate Honda ATF (typically DW-1) using a funnel.

3. Inspect and Replace Transmission Filter

• Sub-steps:
  1. Remove the transmission pan by unscrewing the bolts; carefully lower it to avoid spilling fluid.
  2. Remove the old filter and discard it.
  3. Install the new filter, ensuring it is seated correctly.
  4. Clean the transmission pan and magnet to remove any debris.
  5. Reattach the transmission pan using a new gasket and torque the bolts to manufacturer specifications.

4. Test Transmission Control Module (TCM)

• Sub-steps:
  1. With a multimeter, check the voltage output from the TCM while the vehicle is in the "ON" position (do not start the engine).
  2. Verify that all ground connections are secure and free from corrosion.
  3. If voltage readings are incorrect, consider replacing the TCM based on the manufacturer’s guidelines.

5. Clear Codes and Test Drive

• Sub-steps:
  1. Reconnect the battery.
  2. Use the OBD-II scanner to clear the P0700 code and any related transmission codes.
  3. Perform a test drive to ensure the transmission operates smoothly and no codes reappear.
