The oil level float switch does fail occasionally. I've replaced a couple of them. They are about $40 and you have to drain the oil pan so do the job during an oil change. The float switch is on the left side of the oil pan and is secured by two screws. Make sure you replace the o-ring seal also.

You are the man. Thanks for the help everyone, I've found the part I need. I'll check to see if Phil has it, makes me feel dirty if I have to order from anyone else.

Here is what it looks like for the next person that has this issue.
