I ordered an LS9 MAP sensor on eBay P/N: 12592525 for my S/C'd C7. Made the required changes in HP Tuners for it, and the car now refuses to start at all.
I pulled the sensor, looked inside the nipple and I can see a PCB, is this normal:
If I look at my original MAP sensor all I can see is a metal diaphragm.
Yeah which wires are pinned into ABC/123 on the connector? If they're wired wrong it will not crank. I know because mine was wired wrong and I spent a couple of days trying to figure it out.

Is how my LS2 to LS3 sensor is pinned not sure if the LS9/LSA is pinned that way though.

Thanks for the pointer, I'll check that out.
This is actually for my boosted C7 Stingray. I thought I'd post in the C6 forum because you guys have probably used the LS9 sensor a lot more.
Did I get a junk LS7 MAP sensor?
