Speedo problem

Any have this problem? My speedometer started to act up, like I was going 120 but actual speed was only 45 mph. The stupid pointer sort of went around past 120mph and is now stuck on the bottom side of the 0 mph "pin". How can I get the pointer back around?

Most likely your speed sensor on your rear differential. I had the same problem

Most likely your speed sensor mounted on the rear differential, I had the same problem and had the dealer fix and replace it for about $120

Have you tried the cluster self-test to see how the speedo responds?

I agree that it's the vehicle speed sensor. It's an easy job and you can get the part at a good price. I think mine was a bwd at oriely's and only cost $30-40.

The liberty's have a problem with the wiring for the sensor running against the parking brake cable. This causes the to short or break. When you replace the sensor, run some new wire to a better place.

Haven't tried that, how do you self test the instrument cluster? Is there a button?

You hold down the button next to the odometer while turning the ignition on (but not starting the engine). All the lights will come on and the gauges will sweep through various preset positions. It might reset the pointer to 0, or it may indicate a problem with the cluster itself.

Looks like this:

Thanks, hitting the self test sent the needle back to the other side of 0. Got to remember that trick. I'll check out the sensor too, it's pretty greasy back there, it might just need a blast from some degreaser.
