USA or non USA car. not knowing this makes answers , all wrong.
define crazy.?
if bouncing like mad"? is
1: the cable to it bad. if cable good ,speed is bad, (tests, ask)
2: if the cable gets bad enough the CEL comes on and shows bad VSS. (DTC) veh.speed sensor, dead.
oops 99 is a cust year,
every page in fsm (related) shows if equipped.
cable speed (old school)
electric gauge, no cable. new cars. cusp year.
that means , one looks for the cable to the
tranny or to the not stated 4wd transfer case.

if its a 100% electric gauge
and crazy means bouncing?
its:
A: bad meter.
B: bad power to meter (or loose fuse or speedo connector plug)
C: Bad ECU (hah)
D: vss input to ECU is crazy,

I have a 95 accord and D4 starts blinking and speedometer gozz crazy ya'll know y???


I had the same problem with my 95 accord, your vehicle speed sensor is going bad, the part new is like 100 bucks, you could possibly find one at a junkyard, I had to buy one new, the sensor itself will sit on the passenger side, under the intake hose, its a pain to get to if you have large hands. But it is something that you definitely need replaced

My speedometer only works part of the time. Is there a fix for this?


i have a 2005 monte carlo 3.4 v6 auto with overdrive. i recently replaced the whole cluster because the tach and speedometer was reading crazy.i bought one at a salvage yard installed it and have had no problems for several months.now unfortunatly i am ee=xperiencing the speedometer dropping speed all of a sudden and then it will go to zero and not change at all.the only thing i can think of is the fact that i installed a set of 18 inch wheels and the same day my speedometer started the crazy stuff.so if you have the wrong size tires or wheels i assume that this is the problem.the computer is reading something wrong and the speedometer is responding to this.i hope i have helped you.

2000 ford windstar speedometer needle goes back and forth


replacing the speedometer cable will not fix your problem , your problem is the dash gauge it self on the windstar there is a magnet inside a small metal dish that controls the speedometer when the magnet fails it begins to catch the metal dish randomly , ... witch makes the speedometer go crazy

My guess is that the speed sensor has gone out or the wires that go to it have been knocked off somehow.
