Hi,

I have an 01 Cavalier and just the other day I noticed the oil pressure light lit up on the instrument cluster. At first it came on for a few seconds, went off for a minute or so, and repeated occasionally. Now, a few days later, the light come on at start up and will usually stay on for a while. However, I drove home from work (15 miles) on the freeway and the light was not on the whole time until after about 2 minutes on city streets after leaving the freeway.

The oil level on the dipstick is fine, and I just had the oil changed last month. I'm thinking maybe it's a bad pressure sender or a bad wire and hopefully nothing really serious with the engine itself.

If anybody thinks they can shed some light on this story, please do...I'm wondering what I should be doing about this situation now.

Thanks,
Mike

have your oil pressure checked, have a shop, or urself, hook up an oil pressure gauge (there should be a bung you can connect into somewhere on our engines we can hook and OP gauge to) and go from there, ill look to see if i can find the hooup when i change my intake gasket

Yup, then when the pressure turns out fine. You know you got an electrical problem.

In most cars the oil pressure light is kept by the circuit being open, when the pressure falls to low the circuit is grounded and therefore the light comes on.

Simply ground the switch and see if the light comes on, now unground it and see if the light goes off.
