Help! Speedo not working

[sonyminidiscman]

Hi... 94 corolla....... speedo just stopped working today as i was driving............. but everything else works.........temp gauge works, gas gauge works........... what can i do to troubleshoot..........?

[Rookie_One]

did you verify if the speedo cable is correctly connected (on the speedo itself and on the transmission)

Where is it? what does it look like?

When i am on the highway, it'll go from 0 to 110kmh under 1 sec...........and stay there until i slow my car down to about 20kmh.......... does that mean its a loose connection?

Determine if you have a cable or a speed sensor. Find the trans then the differential. Look for a cable about 3/8 inch in diameter running out the top of the differential or if a electric speed sensor there will be electrical wires running to a sensor on top of the diff.

Might be a bad shaft inside the cable, bad sensor or speedo problem. The speedo could be getting too great a signal input from the speed sensor, be damaged, etc.

If the car has an automatic is it shifting OK, if a cruise control is it working OK and holding a steady speed?

can i see that stuff from top of engine bay? or do i have to jack up the front to get to it from the bottom?

Its an auto... shifting like normal.........no cruise control........

man, its weird driving without speedo.....

the sender is at the back of the transmission by the rear mount try taking the plug off cleaning it with electronics cleaner and reinstall with di-electric grease. My girl friends did this, and i fixed it worked perfect for the last 10,000km

i would say top no way your gonna get at it from the bottom, also take out the intake duct pipe
