well for the past couple of months my oil pressure gauge has been acting funny. its would just go to like 30 while cruising and than go to 0 at idle. now it is constantly at 0 even when driving it. i know this has been covered many times but i am pretty sure the engine has oil pressure. it runs fine, doesnt over heat and is full of oil. is there any way i can check without hooking up a mechanical gauge? thanks for the help

 

I have the same problem. Freaked me at first! My tuner told me to take off the sensor and clean it out. Said there always is a bunch of stuff in there inhibiting the reading.
