Oil light/alarm comes on/off constantly.

[veritasnyx]

Hi,everyone! I couldn't find a Q&A exactly like this one already here,so I figured it'd be best to ask.

We have a 99 Dodge Caravan SE,(3.3L),and just the other day the brake lines busted. We're still chewing over whether to fix them or just find another used car.

The issue is that aside from that,is that the oil light and alarm comes on and stays on until the RPMs get up around the 2 mark and over. It goes off then,but will come back on when the RPMs fall again.

I'm thinking maybe it's a sensor problem (that,and it needs a good oil change;we can't get the damn cap off...not enough room under there!) but I'm no expert.

Any thoughts anyone? I'd appreciate someone with more knowledge chiming in.
