ok, so im having trouble with my speedometer. sometimes it just dosn't work at all and sometimes it works fine, but never throughout an entire drive it always goes out at some point. it reads lower than it should at times and it bounces around alot in the 20-80 mph range... i changed the speed sensor today and it worked for a bit then it started its same old **** again.. any help will be appreciated. thanks

 

What year?

 

its a jdm 2nd gen b16a in a 95 civic ex

 

dDo the odometer and tripmeter continue to work fine when the speedometer dies? If so, the speedometer itself is probably bad.

 

everything works, fuel guage, rpm guage, everything. except the speedometer.

 

i had the same problem in my sohc vtec hatch it ended up being the connector somehow one of the pins rusted out and the white part inside the connector looked like mold hope i helped

 

what do i need to inspect and what can i do to fix it, if it is the connector?

 

theres a few things, inspect it visually, pull a little bit on the pins going into the connector, if they feel loose or look rusted or the pins on the inside look bent or corroded replace the conncetor. if everything looks good visually, and if you have a voltmeter, you could put ur car up on jack stands, connect the meter to the connector, put the car in gear, and start it off make sure your ground, power and signal are good. your power should match the baterry voltage, ground should be one steady number i dont know exact i think 5v and signal should move up when your wheel turns if its bad just look for the same connector at the junkie make sure it at least looks in good condition cut it off about 4in from the connector then cut yours and splice new one in

 

i have the same problem the speedo works intermitently and others it just doesn't, but the trip/odometer only works while the speedo is working. when the speedo quits so does the trip/odo.

 

thats exactly how mine was RPMS work GAS works all lights and Temp gauge work but speedo doesnt work and miles only move when MPH does. i got a 92 si

 

thanks i appreciate it, i'll try all of this tomorrow

 

i replaced the speed sensor AGAIN and the connector and it still isnt working properly. please help

 

In this case, the VSS or its circuit is likely the problem.
