Oil pressure gauge dropped to zero

Not long ago I had this exact same thing happen to me. I pulled over and checked my oil level (OK). Also noted that there were no strange engine noises (normally running). So I concluded it's a bad oil pressure sender.

Got a new one. When I took the old one off I found that it was leaking.

The proof was once the oil pressure sender replaced the symptom never occurred again.

Bottom line. Oil pressure senders can and do fail. Plus the part is cheap enough and easy enough to replace just for diagnostic reasons.
