New to the site. Been looking at it for awhile and some people have some good info.

Bought a ranger a couple months ago and it has some problems I'm trying to get to the bottom of.

First thing is speedometer after the truck gets over 70 mph will start floating around and fall to no reading till it gets back under 70. Also once it drops the abs light will come on. So I was thinking speed sensor. I ohmed it out but don't know the spec.

Another problem is the tachometer is almost always dead. Every once in a while it will show the rpms for a short time and then drop back to showing nothing.

Also have a abs problem that when I hit the brakes just normal braking there is a clicking. Stops once the abs light comes on and the abs system is shut off. Might still be the speed sensor problem I guess.

Just looking for some info. Thanks

 

I would check ground wires in the speedo/tach area then woek toward speed sensor
