Where is oil pressure switch in chevy lumina van 1996?

Hello Tommy,

Your Lumina has (1) oil pressure senor and (1) oil pressure switch and (1) Transmission Oil Temp Sensor.

The battery and the main power distribution box is all right in that area. So, that makes it hard to tell you without more information.

check your vacuum lines

most likely the oil pressure thay get tired and don't read right or not at all it would be cheeper to put in a new switch than check the oil pressure get one from the dealor

Hi, try pulling the connector off your oil pressure switch and using a short jumper wire to connect the terminals inside. The switch is on top of the engine behind the distributor. If this works to keep the pressure up, replace the oil pressure switch. You may notice your oil pressure gauge spiking and/or the engine light may illuminate. This is normal with the jumper wire installed. Please let me know if this doesn't work or you have any questions.

check fuel pressure most likely bad fuel pump. also check your oil sending unit or gauge. chevys run the fuel relay to the oil pressure switch in case the oil is so low the car wont start. sometimes the relay in between this circuit goes bad as well. if all is well check or replace the ignition module (located directly under coils) or distributor integrated if it has a distributor

I would check the EGR valve first........Hope this helps.

may be the oil sending unit is bad
may be the oil pump
is there any noise in the engine?
have the oil pressure check at a repair shop to make sure you have enough oil pressure
if it's ok then have the shop replace the switch while they have the old one out to check the pressure

I believe you mean the EGR valve

If this is a 3.1 Liter,..it's located on the drivers side, on top of the engine. It's bolted down with (2) bolts, mounted vertically, and has a wiring harness attached to the top of it. It has a black plastic top,circular in shape, about 4 inches tall. After removing it, invert to show underside & try cleaning the orifice (with the recessed screw) with a soft brass brush & carb' cleaner....to remove the carbon build-up which causes poor running & "service engine soon" light to display. If carefully removed, the gasket can be re-used,..if it gets damaged, one can be purchased at a automotive parts supply.

If you plan on doing a lot of your own work on this van, I suggest buying a Haynes or a Chilton Manual from a local car parts store for you van, they can give you instructions on everything

its built in the motor
