Comment 1
Most likely sending unit if this is the only guage acting up. -
Comment 2
the Mechanic says it is the sensor on the oil pump so gonna replace oil pump. The pressure has been carrying about 30 at idle a couple of weeks before this happened. when driving it was about 50-55lbs. then shot up to 80 and lost oil out of oil pan trying to go to mechanics. So hopefully not to expensive!!!!! -
