how to fix P0700 code on my Honda Pilot YF3 (2016-2022)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery cable to prevent electrical shorts.
• Ensure the vehicle is on a level surface and securely lifted if working underneath.

2. Fluid Inspection and Replacement

1. Check Fluid Level

   • Remove the transmission dipstick and wipe it clean.
   • Reinsert, then remove the dipstick again to check the fluid level.
   • If low, add the appropriate transmission fluid (Honda ATF DW-1).

2. Change Fluid (if necessary)

   • Remove the transmission drain plug and allow fluid to drain into a pan.
   • Replace the drain plug and torque to manufacturer specifications (typically around 20 lb-ft).
   • Refill with the specified amount of new Honda ATF DW-1 fluid through the dipstick tube.

3. TCM Inspection and Repair

1. Visual Inspection

   • Remove the panel covering the TCM (consult vehicle service manual for location).
   • Check for any loose connections or damaged wiring.

2. Reseat Connections

   • Disconnect and reconnect the TCM connector to ensure a good contact.

3. Replace TCM (if faulty)

   • If issues persist, replace with a new TCM, ensuring programming and calibration according to the manufacturer's instructions.

4. Solenoid Testing and Replacement

1. Test Solenoids

   • Using a multimeter, check solenoid resistance as per specifications found in the service manual.
   • If out of range, replace the faulty solenoids.

2. Replace Solenoids

   • Remove the transmission pan (if needed) to access solenoids.
   • Replace with new solenoids, ensuring correct installation.

5. Final Check and Assembly

• Reattach the transmission pan, ensuring a new gasket is used.
• Reconnect the negative battery cable.
• Clear any stored codes using the OBD-II scanner.
