my accords speedo cable works very rarly, i had a crx and it was very visible in the tranny. where is the speedo cable located in the accord? any had this problem?

 

The 90 Accord doesn't have a speedo cable. It uses an electronic VSS (vehicle speed sensor). This sends an electical signal to the speedometer where a module then converts this signal to drive the speedometer motor.
Your VSS is probably bad.

 

where is the vss located at?
