This is not a Checker/Pep Boys/Autozone POS. It is GM part number 16040749. I have the invoice as proof if you want to see it. Bought almost exactly one year ago, absolutely nothing wrong with it because it's NEVER been used.
I'm selling because 3 BAR is total overkill for my setup. You can buy this same sensor from gmpartsdirect.com for $49.08 + their $9.95 S&H fee.

I'll sell it for $45 shipped to you. Canadians shipping nego. Don't bother lowballing me.
