I havbe a 2000 Buick LeSabre Limited with the 3800

I have a 2000 Buick LeSabre Limited with the 3800 V-6 engine. The digital oil prersure reading started fluctuating between 75psi-105psi a few days ago. It is now reading a constant 130psi. I suspect the oil sending switch is the problem but I'm not sure of its location. Help please.

I need to locate the camshaft sensor on a 3800 series ii V6


Here is a link with a diagram about half way down the page that points out the sensor as number 8. It looks like it should be near the oil filter just up and over a bit. There is some good info on this page to that may help. Good luck! Have a great day!

1995 buick lesabre limited, oil gauge issue


Could be two things, your oil pump pick tube is clog, oil pan would have to be drop to check, or your camshaft bearing worn causing low oil pressure,I would not say piston rod bearing or main bearing, cause there's no knock noise. You will have better oil pressure when cold due to oil much thicker. so I would forget about a bad oil pump.
