Not sure what year your car is, but according to my '88 service manual electrical supplement, you should be able to check the resistance of the sensor while heating it to a known temp (might be easier said than done). Here are the resistance vs. temp values:
570 Ohms - <150 deg F
369 Ohms - 160 deg F
135 Ohms - 220 deg F
75 Ohms - 261 deg F
47 Ohms - 300 deg F

Don't know how much that will help you, but maybe you can do some checking.

I replaced mine to check for a long crank time(Killebrew) and i lost 10 psi
at idle!! Car starts the same. I kept it for scoots and giggles.

As you can see the resistance should be several kOhms at room temp and a few hundred Ohms at operating temps.

I paid under $40 at my local Chevy dealer.

You need to meet Jeff Kopp. He get wholesale prices on everything GM and he actually works at a dealership. Total price on the oil temp sensor, shipped to my door was $22.18

:cheers:
