speedometer problem

[Aproductions]

im sure this problem is prett different from the other speedometer problems on here. anyways 1999 eclipse gst 5 speed....


sometimes the speedometer sticks at 0 until i press the black trip tick button and then it works. other times it shows 0 until im at about 20mph then it works. i also feel like it is a bit off sometimes too like i dont think im going that fast. any ideas ?

check the speed sensor on the tranny. It might be loose.

if that isnt it what else would it be thanks

Check the little plastic gear that is connected to the sensor inside the tranny. See if a few teeth are chipped up and worn down, that could cause it to be off because mine was doing the same thing until I replaced the little gear for 12 bucks. Good luck.

where on the tranny is the speed sensor and do i have to remove it for the gears?

You might have to recalibrate your gauge. But you should just be able to pull the sensor out, it'll be tough because the gears are lined up. But it should come out with a decent tug.

so i pull the sensor and gear out if then i can replace it? and where is it on the trans?

 

[kenuwine4g63]

The gear is attatched to the sensor. Its on the transmission. let me see if i can direct you(my car is not outside so i cant take a pic) from the passenger side of your car its a orange plug on the transmission. Or if you look down the engine compartment like you were trying to look at the ground its on the tranny not near the front but towards the back and there will be a plug going into your tranny. Unplug the plug and pull the sensor.

so then the gear will come out too? and thanks alot

 

[kenuwine4g63]

Yea the gear will come right out. From the way its designed, it looks like its works like,....The gear on the end of the sensor sends a signal of how fast its spining and then it sends a signal to your gauge that shows how fast your going and the distance being traveled at that speed. The gear is connected to the sensor.

could my actual gauge cluster be the problem?

 

[slow gst]

Take the cluster out and see if it's unplugged if you think that's your problem.

Any chance you took the cluster out (maybe to put in some new gauge faces?)
Lol....just thought I'd ask ### sometimes pressing too hard when putting the needle back on will cause the speedo to stick...
...failing that, if you have any 2G buddies, just swap clusters and see if it still happens; might help narrow it down
