The D4 9 blinks is for the vehicle speed sensor (VSS) on the transmission. Replacement is not too difficult. I would suggest you download the shop manual from the spooner link posted in the online manuals thread in the DIY forum.

When you first turn the key to the II position and not try to start the car, does the check engine light turn on for about 2 seconds?

 

sorry took so long to reply. yes cel light does come on 2 sec. but prob is i got a new vss and installed today just like instructions.. was pretty easy thanks for that!!! took it for drive and same thing no fourth gear d4 starts blinking only when trying for 4th gear.. checked the d4 code again and same thing 9 short blinks... 94 accord ex.... thanks i really dont want to take it to a shop youre help is greatly appreciated...

 

I made a mistake when I posted before. The code 9 is the countershaft speed sensor. I am sorry about the mistake.
