Code P0780 means: A/T Concerns
As you do not list the code you are reading, it is impossible to answer your question.
I have never heard of a code 24 on a Honda.
code p2647 is oil pressure switch is that correct
coolant temp sensor
diconnect the battery then connect it
Left Front Fuel Supply System circuit fault
it's code 6 blinking out twice. and it's temperature sensor. usually meaning it came unhooked. sometimes bad. about $12 at part store. it's on the side of the head.
Trouble code P0135 means: O2 Heater Circuit (Bank 1, Sensor 1)
exhaust recirculation system
Take a look at the lift sensor mounted on the left front fender.
No one can tell you the code as it is specific to the radio in your vehicle. Go to the Honda web site and sign up on the Owner's Link. With the VIN # you can get the code there.
