"Jumping" speedometer...

[gheba_nsx]

Hi all,

it is now the second times this happens: when driving I notice that the speed indicator goes from 60-70-80 kmh to 0 kmh for a moment and then bounces back to the correct speed.

Everything happens very quickly, 1 second or less...

I had it happen yesterday a couple times and I noticed the same one month ago.


What can it be? The speed sensor faulty or dirty?

Thanks for helping!

Hi gheba_nsx,

See this thread from last week as I am having the same problem and am a little farther along (thanks to my friends at the track and here on Prime).

My old speed sensor should be here early next week so I will keep you posted.

Thanks Nick, I'll send you a PM!

(incredible how sometime the problems are coordinated between NSXprime members! )

I had this problem and Devin from payne technologies diagnosed and fixed it in 5 seconds. My problem was that the speedo cable or wire had loosened at the connection to the (transaxle?) on the trunk side, center of the engine. he hand turned it tight and no more problems. Hope your solution is as easy. BY the way, it also caused me to throw cel,s and lose power steering.

Thanks WOODY, I tried this yesterday on Nick's advice (I also did put some contact cleaner on the connector). I drove it a little and I had no problem... I'll wait some more km and I'll see if it is really solved.
