oil exceeds max warning comes on at same place on same freeway!!! (more)

my oil max warning light has come on 4 times at exactly the same place on a freeway...the road is not bumpy or anything...can this be an electromagnetic disturbance or something? or should i be concerned? if i turn off the car and let it reset, the warning does not come back on....

It is possible that some device that monitors<br> road traffic (eg. just counts cars) is able<br> to interfere with oil sensor. Those monitoring<br> devices often have form of a big electromagnetic<br> coil. But there are a buch of recalls on the<br> oil sensor displaying strange messages, better<br> have it checked at your dealer.

It might be a hill.
