Default 2003 Chevy Blazer with flashing "Check Gauges" light

On my 2003 Chevy Blazer the "check gauges" light has been flashing, and at the same time, the oil pressure gauge will drop when the light flashes, but comes right back to normal. Any suggestions?

When was your last oil change? You really shouldn't be driving...at all...if you're losing oil pressure for any reason. Thats about the shortest how-to on killing your engine.

Could be a loose connection at the oil pressure sending unit underhood. It is located to the driver side of the distributor near the brake booster.

Would the loose connection trigger the check engine light?

It would cause a check gauges light (as the OP stated) as the PCM thinks there is zero oil pressure. But should not cause a check engine light.
