Hello, It is a pleasure to get to assist you.
Sorry to hear about your issue.
To answer your question, Yes a fluctuating oil pressure could mean the sending unit is going bad.
But if you have a leak somewhere I would first repair the leak.

Could it be the sending unit itself leaking??

I've had this vehicle for 3 yrs. It's had this leak the whole time I had it. I thought it was the oil pan gasket. I replaced it but that wasn't it. On a second look I saw it was leaking down the back of the motor. I thought maybe it's the rear main seal. But I figured if it was the rear main,it would be dumping oil. But the leak seems to stay the same.But my main question is,should I replace the switch and the sensor? One or the other?? How can you tell which one is leaking??

You should be able to look at tell which is leaking.
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.

Can fluctuations in oil pressure by signs of a bad sending unit?? I also have a oil leak coming from the back of the motor. It doesn't look like my rear main seal is bad. Also my check [engine](/topics-engine-chevy/) light is on. Mechanic's Assistant: Does the light stay on, or does it blink? The light stays on. Mechanic's Assistant: What is the make/model/year of your car? 2002 Chevy suburban Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?
