The Oil Pressure Switch is located:Under hood, center, rear engine area, driver side of distributor, mounted in block. Here's what it looks like.he oil pressure switch is mounted to the top rear of the engine.

1. Remove the electrical connector from the switch.
2. Remove the oil pressure switch.
3. To install, reverse the removal procedures.

pretty common same thing with my 2001 2 door chevy cavalier. its the valve cover gasket, you need to replace it.

i'd agree sounds like a faulty oil pressure switch.doing a pressure test with a guage will
tell for sure or just replace switch ($15 part)

good luck

The oil pressure switch relays the oil pressure in the engine to the instrument cluster. The switch will illuminate the OIL PRESSURE light if the oil pressure drops below 2psi (13 pa). The switch is usually located on the side of the engine, under the intake manifold on the 2.2L engine and on the side of the intake camshaft housing on the 2.3L/2.4L engine.

Other, the low oil level switch activates the OIL light in the instrument cluster when the oil level in the pan goes below a certain level. The switch is mounted on the oil pan.


Hope this helped (remember rated this post).

If it is not mounted in the oil pan,that vehicle has not.

You can buy a florescent dye to add to the oil and a light to make the dye really shine.
Clean the engine with "brake clean" from a spray can at the oil leak areas ....then run the engine.
Check for the start location of the leak.
Start with a short run time ....... then longer run time if necessary until the leak(s) show.
With or with out the dye ......this brake cleaning method should help locate the leak(s).

Oil leak locations could be...in order of the most common on your car are........valve cover gasket,oil filter,oil pressure sending unit,drain plug,oil pan gasket,crank pickup sensor,rear seal.
