2002 Grand Caravan EX, 6 cyl. My low oil pressure light started coming on when you slow down. It goes off as soon as you get on the gas a little bit? Checked oil and it was low. Added oil to proper level and light stopped coming on for about 1/2 a day then started blinking again. Any ideas? Does this sound like oil sending unit or oil pump problem?

 

what year and engine

 

I have the same problem on my 98 Grand Voyager with the 3.0 V6.

Oil Light came on the other day. Oil was a little low so I topped it up. Came on again today so I decided to do a full oil change, filter and all. Went to the grocery store and now the oil light won't really go off. While accelerating it goes off but at idle or when there's no real load on the motor (cruising) the oil light is constant.

Any ideas?

 

Copied from post to 98 Voyager.

You need to pull the oil pan and oil pickup tube immediately. The pickup tube gets clogged with sludge at the screen. I have a 97 3.3l with 143k mi. and had this happen when my wife was driving a few days ago. I am looking for a cheap used engine now. My oil light would flicker once in a while and I didn't worry much about it. Even when I pulled the pan I didn't see any buildup, but when I pulled the pickup tube it was loaded with gum - and since my wife drove it till it stopped there was also a lot of shiny metal in it too. My engine will still run, but it sounds like the crankcase is going to grenade every time I start it.
