I have honda accord 91 ex and the speedo keep flashing and my speed sensor having problem too how can i fix it and where is it locate at

 

If by the speedo flashing you mean the speedo intermittently works, its probably a sign your transmission is about to lock up and come through the floorboard!

 

speed sensor in my '90 accord just went out and got one off ebay for 38 including shipping b/c aftermarket from advance is 150 gp sorensen!!! no way i'm paying for soemthing like that when i can get it off ebay for 38 with a lifetime warranty! i can pay for alot of shipping before i would have to pay for 150 advance sorensen! but ya no biggy, the one i got off ebay came with a new pin drive and was very good quality. just put multi-purpose high heat grease on the new one to lube it up good and make sure your o-ring that seals it is in good condition or in need of replacing and lube it up too. best of luck

 

you need to search for vss because this problem has been gone over A LOT.

 

ugh...I hate the stupid speed sensor
