Camshaft sensor, Need Help

[scuba dave]

Could someone tell me what the specs (resistance) is for a 1995 Aurora camshaft sensor. I had the car scanned and they said I needed two CRANKSHAFT sensors. They were unable to llocate any at thier resources so I took the car home and put two in from the stealer. Did nothing, car still runs like shit. Took it back and they scanned it again to no avail. I think thier scanner got broke when it slid off the top of my car ( 24 x 1/4 inch deep scratch on the top of my car that they know nothing about, the dust from the scratch is still there). Anyway, should there be some kind of signal from the cam sensor when the car is running if i back probe it with a volt meter? One of the codes was #41 "no cam signal" along with 32,34,41,53,71,83,95 Map msensor is ok and replaced the crank sensors. My resistance on the cam sensor is 1850 ohms warm. Any ideas would be helpful
