Originally posted by itsaslow95 Well on Sunday I put an oscilliosope on it.(buddies' snap on verus) and I'm not getting anything out of the sensor. I have the 8v+ going in the center wire, and I believe the ground on the left if your looking at the connector face.
Also I did not ground the block with the big post on the back, I have a ground to the tb on it right now, I also have been jumping the sensor's ground to the battery ground. Could this ground strap maybe be my issue? I'm going to try it today hopefully. Thanks!!
You have it wired wrong, the sensors ground is always the middle pin. The two outer pins are VDD and signal. (Pin1 and Pin3) If you can see the stock wiring colors, look for the yellow wire (this is the power wire). If you don’t know the stock colors then swap the two outer pins and try again until you get a signal. The (CPS or CAS) sensor is interchangeable on all years. You need to have a solid ground to the chassis/engine if you want anything to work properly.
