Hey guys, I was driving home last night on the highway and all of a sudden the speedometer goes crazy. I know I was doing about a good 70mph and the speedo started going buck wild. It went from like 60 to 120mph back and forth, back and forth, then sometimes it would go past 140mph while I KNOW that I am at a steady 70mph. Then when I stopped by a convenience store, while the car was parked, the speedo was still moving and I was gaining mileage while the car was stationery the whole time. I gained about a good 5 miles while the car was parked lol. And when I rev the car hard while it's parked, the speedo goes crazier too.

Does anyone know what the problem is? Could it be a sensor, or an ECU wire or something? Any advice would help a lot! Thanks for your time guys.

 

i got the same problem, lol i was going abou 70 then i stepped on the gas and the speedo goes crazy. I think in might be a sensor, speed sensor.? does someone help both of us out.

thanks for the support, haha.

 

I'm pretty sure your problem is going to reside in your speed sensor... I don't much about the subject, so maybe someone else can chime in...

 

ya most likely the speed sensor is whack

i dont know a whole lot about it but it's on the tranny (differential area usually).

what year is your car? that would help a lot.
