I have a 1993 sohc mx-3. The gauge in my cluster that tells me the speed of the car isn't working.
This is driving me crazy because I can't tell if I'm speeding or going to slow. I think it's the "Speed Sensor" because all the other gauge on the cluster work fine. Can you guys help me out so I can fix my miles-per-hour gauge? Do I have to buy a new speed sensor or can it be something else? What colors is the speed sensor wires? Which wire plug on the "ECU" is the is the speed sensor one for the 1993 sohc mx3?

Hummm, it is suppose to be a cable that turn that let you know your speed..<p>The needle in a Mx-3 1.6l dohc is moving with data from the ECU.. not the sohc..

Re: engine control system
I don't have a dohc 1.6L egine. I have a sohc 1.6l engine. My speed sensor isn't cable.
Re: engine control system
If you have a 1.6L SOHC with manual tranny your speedometer is cable driven. <p>Look in the engine bay about where the back of the dash would be. You should see a cable (not your throttle cable) follow it to between the back of the engine and the firewall. <p>This is where you fill your tranny BTW, Use a 10mm driver and remove the bolt. <p>Pull up and you should see a plastic gear, if you don't your screwed.<p>If its there turn it while someone is in the interior looking for needle movement. If none you speedometer in the dash cluster might be screwed. <p>info based off of a 1993 1.6L SOHC Manual tranny.
Stop the rave.... I wanna get off!

Re: engine control system
Thanks for the replys. Sorry about that the speed sensor is a cable. I couldn't find it before. I took out the cluster today and made sure its plug. I haven't drove it yet because i'm block in my friends house right now. If it doesn't work now, then what do you guess think it is? The next thing i think it could be is the miles-per-hour gauge itself but its werid because all the other gauges work on the cluster. What other reason could it be if it doesn't work?
