VSS reading from PCM
2007 LQ4.
Think the wire is C2-> 50. Dark Green and white. Everything else on truck works - but having problems with the dakota guage displaying speed. I know the PCM is getting speed signal as I can see it in HP Tuners. I get 10V DC at the wire ..... and doesnt seem to change muich with rotating the wheel with ignition on. Any ideas on how to diagnose this one.

Re: VSS reading from PCM
Got 2-7 volts roughly when in gear at various speeds ....
Hooked her all back up .... works ....... not sure  Speedo might be off but the gauge cluster has various ways to adjust so maybe good ....
