usually it will drop to 0 and stay there.if i turn it off and restart it will come back up a little then drop back down again,no check engine lights or anything abnormal with engine while driving.
Thanks for the reply
hi,
i have a 1995 toyota 4wd v6,usually when the engine is cold and i start up the oil pressure guage reads normal,then it will read 0.none of the check engine lights have came on and it runs just fine.im thinking its the oil sending unit.just wondering if anyone have dealt with this...
