Display Problems
I just purchased a 1990 Accord and have some display problems. The MPH gauge and the odometer are not working. Well, the odometer works a little. Every now and again it will roll over a couple of miles and then go another 200 miles without doing anything. The Tachometer is ok, but seems to jump from 2500 to 4000 in a hurry. I know from experience that there is a modulator that the display is tied into. This is a stick, so I don't know if it will be any different than on my 1994 explorer. Any thoughts? Thanks

RE: Display Problems
Sorry for the delay
the speed sensor is located close to tranny
first check the Fuse No 1 ( 10A ) in the dash fusebox
if ok check the speedsensor for ground - disconnect the harness
if you look inside of the connector with the latch on the top - the right pin is ground (black) - d check it with the body for ground- should be continuity.
if there is - check the middle pin (yellow) with body for voltage - (do it with ingition ON) if theres voltage
check the left pin (orange) for voltage with body (ignition ON)- should be apporx. 5V.
if all conditions are met - replace the speed sensor
however it's been recorded with honda that in some cases the whole Main Print Panel has gone bad in which case you have to replace the Main print panel - which you can get at junk yard (check that first)
