Vehicle speed sensor wire at ECU conn 1 A9 Blue/White pulse signal wire.
How can I test if its getting a pulse?

I have an aftermarket dash and I'm not getting any reading (no speedo).
My connection from the s2k ecu (blue/white pulse) is perfect all the way to my digital gauge.

The engine is 2001, is the pulse signal wire blue/white? Is this 5V ?

Thanks

 

anyone?

 

I have no idea...but check your Helms manual. It usually has that kind of info.

Have you checked the connection to the speed sensor at the tranny?
