Engine Mechanical problem
1997 Ford Ranger 6 cyl Two Wheel Drive Automatic 230000 miles

Hi I have a 97 ranger splash and now when the truck warms up the oil pressure sensor goes to zero when I let my foot off of the gas but not all the time a couple of people have said that it maybe the oil pick up or the sensor what can I look for and do to test this. thanks

Find the oil pressure switch remove it and hook up a mechanical gauge -if normal replace the switch abnormal could be oil pump/engine bearings/etc-
