My bosses 93 civic ex has a speedo issue. One cold starts the cluster moves fine but after about 30 mins to an hour of driving the cluster goes nuts. It moves erradically and doesnt go up smoothly. How do I know if the speed sensor is bad or the cluster is bad? I thought it was a cable driven speedo like my DA but its electronic. Anyone have any ideas before he has to go buy a cluster or VSS?

 

anyone?

 

holy cow.....45 minutes without a reply....ohhhhmy......gezz kids these days....try waiting 2-3 days for a response or a new thread.....yes welcome to 1995 honda.hybrids.jp yeap that's how it was back in the day!

 

definately check the grounds first.

mine did pretty much the same thing. at random times the cluster would go nuts for a few seconds and then stop. i found a loose ground wire the next day, and it hasn't done it since.

but the vss could be going bad also ... they tend to do that.

 

thanks! Anyother suggestions?
