The chevy garage just changed the oil pressure sensor and the gauge still drops to zero
Use caution you might actually have low oil pressure. Also check the connection. If it loose this can happen too.
If you begin to hear ticking or knocking it is low oil pressure and stop driving it before you blow engine
The engine is not making any knocking sound. The engine is running good. What connection are you talking about?
Hook up a cheepo beepo mechanical oil pressure gauge for testing purposes. That'll tell you if it's really an engine problem or an electrical problem. Please let us know what you find out. HTH. -Jim
Connection on the oil sender.
Seems lots of users having issue like this. Replacing the oil pressure sending unit repairs most. That thing is a bear to reach way back there on the back of the block. I would just double check that they fully snapped the wire harness into the unit.
