I hhave a 1995 honda accord US wagon and , the engine light has come on and the d4 light has been flashing ! the speedo has been fluctuating from 0 - 140 kph and sometimes not even moving !

I have checked the code from the flashing d4 and i get 4 short flashes and then i get 9 short flashes , can anyone tell me what those means or point me to the right direction of what i need to do please !

Any help would be much appreciated

 

I'd be most suspect of the Speed Sensor.

 

i agree with the Dude,,, do quick chk on drive side shock tower under hood there is a plug with an orange wire in it ,,make sure that wire is not damaged ,if ok most likely a bad v.s.sensor

 

My accord got the same problem, I checked the speed sensor as what the book says and found out that the sensor is okay but still got an engine light and speedometer stops

 

Hello desserthonda what orange plug is it and where's the location
