Well basically im writing because yesterday when i started my JGC Laredo '14 i noticed that the check engine light didn't go away... so today i drove it to the dealer to get it scanned, i dont have the code but dealer said that it was the oil pressure sensor then showed that when the engine its not running the oil pressure gauge shows 90 psi -or lbs i dont remember the unit- totally no sense because when the engine its not running should show zero in the oil pressure page. Dealer also said that if im going to travel in a few days i have nothing to worry about and i just wanted to check that last information with you.
What do you think about it? some recommendation maybe?
Totally have no idea how could this happen.
PS: The new sensor should be arriving in a week or so.
