For my swap project I need some info on PCM pin-out of the Vehicle Speed Signal for a 2006 Cobalt.
I have a 2004 ION and 2005 Cobalt PCM connector pin-out and these both mention a VSS sensor (mounted at axle) wired between pin C3-44 & C3-45.
Think the 2006 uses the ABS speed signal (correct?), but has something changed in the PCM pin(s) used?

Thxs,
(And a 2006 PCM wiring diagram is very welcome!!)

 

Bump for more info:

I have a 2004 Ion LSJ harness that has a 2p connector for the VSS sensor mounted over the axle behind the engine. (to C3-44 & C3-45)
My other LSJ harness (2006 Cobalt) is similar, except it misses this 2p VSS connector. Correct, as the 2006 use the ABS for speed signal. But WHERE is the ABS signal connected? Logic says this should be on the blue C1 connector.
(the pin-out here https://www.cobaltss.net/forums/tuni...?t-38412.html= is for a 2005 Ion/Cobalt with the VSS sensor)

Anyone?

 

you cannot retrofit without an ecm flash change it is not possible the vss signals are different tooth counts, im shaft in 04 to trans case 05 and up. youcant swap ecm's due to bcm compatibility. so. good luck.

 

Of course I need a reflash. And not only for the difference in tooth counts...
This is going into a rear engine car, so forget all Cobalt / BCM systems.

06 PCM, 06 engine harness. O6 tune. Just need an 06 pcm pin # for the ABS speed signal so I can finish wiring the blue C1 (car) connector. That's all...

 

Looks like it is on 2 pins.

Pin 44 VSS Low signal - PU wire color
Pin 45 VSS hight signal - YE wire color

 

Hmmm...
Double checked my other harness and pins C3-44 & C3-45 are still there. Looked a bit better and found a different connector at another place, wired to #44 & #45. :-)
Looks like you're both right and the PCM pins did not change.
I thought the ABS signal was used for the 06, but apparently the VSS changed from a shaft mounted sensor (04) to a trans mounted sensor (05 >), correct?
Anybody know the exact 06 tooth counts?
