Guys got a 2001 can't get the tach to work engine runs great so CPK is working any ideas?

 

The PWM signal for tachometer is on ECU's connector C0637 pin 17 (white/grey wire) if that's what you need. Its a 12V signal, 4 pulses per revolution. So that's at least a place to start looking if you've got a signal or if its an issue inside of the dash.

 

thanks

 

If you have an ODB2 reader you can pull tach data from the ECU. If you can get the RPM from the port but it's still not showing, it's most likely going to be an issue with the dash.
