Tech Notes for P0796 Honda

When a transmission solenoid has malfunctioned, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is dirty, it's recommended to change the transmission fluid and if possible, remove the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure, and that the transmission will need to be rebuilt or replaced.

  • I have a 2016 Honda Accord V6 Touring that is harsh shifting similar to what you explained. My mechanic did a diagnostic and I managed to note the trouble code A/T clutch pressure control solenoid......My mechanic claims I need a new transmission because the solenoid that has failed is not sold separately from the valve body and the cost of the valve body is very expensive and almost equivalent to buying a new transmission. Can you provide me with any perspectives on this issue? Please and thanks in advance.

  • He is correct, you can't replace just the solenoid, but you can replace the Secondary Valve Body, which is less expensive than the Main Valve Body or the transmission assembly. You should get a second opinion from a transmission shop, Also, is you Honda already out of warranty? you may still have some type of warranty, check with your local dealer.

  • I have a 2009 Honda Pilot with this code, The Transmission won't shift I haven't taken or towed it yet is this something I can change myself? The trans seems to be in a limp mode.

  • You could try just clearing the code and checking the transmission fluid level and condition. Low transmission fluid could set this code. If fluid is dirty (dark brown and smell burnt) then you could try changing the fluid.

  • My 2013 honda accord gives a fcw system fail and a flashing 03 code . The car takes off from a stop seemingly in 2nd gear and will not shift and at about 2800 rpm the engine cuts out until slowing the rpm, but I can cut off the engine and restart and it runs and shifts correctly until this happens again

    • It sounds like you're experiencing a few different issues with your 2013 Honda Accord. The "FCW System Fail" message refers to a problem with the Forward Collision Warning system, while the flashing "03" code and your engine/transmission symptoms could indicate a transmission-related issue. The DTC (Diagnostic Trouble Code) P0796 you're seeing is specifically related to the transmission.

      Start by checking the transmission fluid condition and level, as this is the simplest and least expensive step. If the fluid is fine, the next step would be to inspect the wiring and connectors for any obvious issues. If those look good, replacing the pressure control solenoid 'C' would be the next most likely repair.

      If the issue persists after these steps, consider looking into software updates or reflashing the TCM. Only consider replacing the TCM if all other options have been exhausted.
