Does anyone have the pinout for the ECM for a 2009 HHR SS with the automatic transmission.

I am specifically looking for the locations of the 3 wires for the ckp crank position sensor.

Thanks for any help

 

I don't think they are different. But it is the 96 pin conn.

 

Looking at the chart it looks like the purple and and light green wires from the crank position sensor must be pin 45 and 46. They were the only purple and light green wires that did not have a specific description.

 

Lt grn is 5V ref, purple is low ref, yel is signal.

 

I did confirm that

pin 45 is the 5 volt reference

pin 46 is the is the low volt reference

pin 35 in the crank position sensor signal
