1994 cadillac sedan deville 175,000 4.9l

[quote:08d9816f89="damantil"]I have a no start on my car with a code 12 for no distributor reference. I heard the most likely cause is a bad hall effect sensor in the distributor. What exactly does this sensor look like?[/quote:08d9816f89]

its called a cam sensor, you have to remove the distributor to repair, and a timming light is required
