Ck.engine light & TC light come on-HELP

[todddejag]

I.m a new NSX owner & love my '91, but a few strange things are happening. Seems when I drive over 80, the traction control & ck. engine lights come on at the same time. Also, the "speedo" needle drops to "0" or bounces up & down. Tach remains ok & car runs well. What is causing this? What do I need to do? Please help if you can!

Sounds like the speed sensor.

go to the faq and read the section on pulling your codes.it is very easy.but as the guys stated sure sounds like your speed sensor.pull the codes and if it throws a 3-2 you will know for sure
