In a JAM, stuck in FloridaEngine oil pressure light came on today intermittently

[Johnrude]

Hi Guys, LONG POST I'm a newbie to this forum, sorry to take up valuable time. However I've spent the last two hours searching the archives and latest posts and I can't find my answers.

First off the car is my sister's 2000 Maxima. She purchased it new and has kept it serviced at her regular shop and I've done a lot to it myself. I work on Outboard motors primarily, but I love working on anything, especially when I can help someone out financially. I pay for all the parts and won't take a nickel from my sister for any kind of work on her stuff.

The Maxima has 216,000 miles. The SES light is on, code p0400, egr stuff. I don't know if a diagnostic machine can tell positively if it is the egr or something else. From what I've been reading and hearing I need to go ahead and spend the money for a new egr.

Anyway, I'm in a jam right now. I'm in Florida and need to go to Atlanta,GA Wednesday to meet up with my family for Turkey day. HOWEVER after fishing all day today, I hopped in the car, slap wore out. I fired it up, drove 35mph for about three miles. When I started putting the brakes on the oil pressure light flickered, then went out when I stopped.

I left that place thirty minutes later, went to gas station. Light came on again when I pulled up to gas pump. I checked the oil and it was full from the last oil change 2000miles ago. So I hopped back in the car and drove to the canal to clean fish and the oil light stayed on for the entire one mile drive.

After cleaning my fish, I drove back to my place a couple miles away and the light never came on,flickered or anything.

So, I have most of my tools with me. I would like to get a pic of where the sending unit is and how to test it with my DVOM meter. 216,000 is a lot of miles. I don't want to take any chances and have a catastrophic engine failure driving it to a shop, especially when I can perform enough of a test to see if the problem is real or not. I do have pressure gauges that I could hook up too.

I just need a helping hand, a few pictures and some advice on what I should do.

Sorry for the looooong post, I'll give my Bud Lite to anybody that can give me some real help.

Thanks in advance,

Johnrude

Here's a link to the lubrication and cooling section of the service manual. Hopefully it will be of some help; it does have pressure check diagnostic procedures. Unfortunately I can't find a good picture of the oil pressure sending unit location...the FSM doesn't even seem to have any good diagrams of it.

And welcome to NICO!
