LLS Posted September 10, 2007 Share Posted September 10, 2007 If the ODO is not changing, then it is a speed sensor. It's not getting signal to the cluster. Quote Link to comment Share on other sites More sharing options...
JIBBBY Posted September 10, 2007 Share Posted September 10, 2007 Remove the cluster and re-attach the leads you could have a bad connection...If not your cluster is dead or a bad speed sensor... Junk yards will sell you a new cluster for like $400 but it will change your mileage... Quote Link to comment Share on other sites More sharing options...

It was working beforeEmail me at kouterbridge@hotmail.com I realize I might be too late, but I had the same thing just "mysteriously" happen. I'm driving down the road at a steady speed, the speedometer goes to 0. Then to 120. Then down to 0. Then 60, 80, 40, 120. . . and 0. I'm thinking, "Oh no." So I read about beating on the dashboard and I look at every post I can find about the instrument cluster problems. . . Eventually I get the diagnostic code. I take the car to the dealership. They confirm that it is. . . now get this. . . a transmission speed sensor causing the problem. I'm having a little problem with rough shifting. I tell the dealer to "just replace them both." At the same time we do the 90k mile service (timing belt) and find a leaky water pump. . . and they want to do a complete transmission service, and. . . by the time I leave the dealership I was about $1,700 down by the bow (my aft being $1,700 lighter). The speedometer worked **almost** until I got home. $430 later I have a new speedometer sensor (the dealer was happy to do that for me) and everything seems to be okay (knock wood). BUT - I still have a little rough shifting. If it were anything but an LS400 from the early 90s ('92) I'd think the transmission was okay, but it isn't shifting as well as either of my 1991 ES250s were when we traded them at over 140,000 miles each. My point? If I'd just *started* with the speedometer sensor, the most obvious place to start, and ignored all the "noise" OR I had just taken it to the dealer in the first place and said, "The speedometer isn't working, can you tell me why?" I think I'd have gotten out at least a few hundred cheaper. Sometimes paying a dealer too much is cheaper than trying not-to. Bret Quote Link to comment Share on other sites More sharing options...
