: Oil gauge broken... easy fix?

11-10-12, 09:28 AM
Hi guys,

The Oil Gauge in my '05 ESV is broken. It goes all the way up instead of staying where it should be (in the middle) . Oil level is okay since I checked it when I first saw the gauge go all the way up. Is there an easy fix foir this problem?

Any help would be great! Thank you!

Sounds like it may be a loose wire or bad sending unit.

Is it an easy fix / DIY kind of deal?

I don't know the level of mechanical abilities that you possess. I do not think it would be a difficult DIY, although I've never replaced an oil sender on this particular type of car, nor do I know exactly where it is located.

Could be 1 of 2 things:

Oil sender switch maybe bad (it happens on these engines). You would need a multi tester (electrical) to make sure you are getting the right voltage sent. I am sorry off the top of my head I don't recall what it is.

Could be a "stepper motor" inside the cluster. It is the actual motor that the gauge arrow slides on to. Do a search here "stepper motor".

Is the info screen showing anything when the gauge does this or not?
