Ihave a 96 ssei and was wondering if anyone could tell me where the oil pressure sensor and sending unit are and how to replace. it would be greatly appreciated.

Go in through your right front wheelwell (tire off, inner liner off), and you'll see it sticking out the back of the motor pointing towards the firewall. Just above the oil filter.

thank you . i would be lost without this site also i was thinking of getting an online factory manual for my car looked into alldata is that a good one or do you have a better recommendation ?

Buy the factory service manuals from www.helminc.com

Do an ebay search on 1996 Bonneville Manual. Many Factory manuals at the bottom of the page.

what should the oil pressure be at idle on a 1996 ssei thanks.

tpulliam79,

I actually just replaced the one on my 96 SE today and took some pics. I bought the part from Advance for $20 and it took me about 25 minutes to replace it (including jacking up the car and removing the tire and inner liner). I used a small screwdriver to remove the wire clip and channel locks to unscrew the old sending unit. Hope these pictures help.

From inside fender well with tire removed. My finger is pointing to where I unscrewed the sensor from:

thanks for the pics and details

If you're long enough you could just jack up the front end of the car a bit and change it by going through the top engine bay. This was much easier for me.

Generally speaking, above 40 psi. Your oil pressure should not drop into the red part of the gauge, ever. Oil pressure varies with the viscosity of the oil, which is affected by temperature and dilution. Oil pressure also drops when the spaces it is pumped through grow larger through wear.
