Question '06 Denali Oil Pressure low & fluctuates ???

Ol' wise ones...

Last month my '06 Denali 1500 developed an oil pressure reading which pegged out at Max even when the truck was off, but electrical accessories engaged. So, I - with the help of my daughter with tiny arms/hands - completed the PITA job of accessing and replacing the Oil Pressure Sensor. It appeared to fix the issue with normal readings for the month, then this week I now have low and fluctuating readings, with warning bells and ECU readings. I can't determine one scenario which causes the reading to fluctuate: under load, hill, idle. There is no engine noise or temp issues to make me think it is a mechanical issue. Your thoughts of where to proceed. I've read a few paths:

1. We did not replace the filter below the sensor/switch because they were supposedly not used until '07. I almost installed one anyway, but wasn't sure the channel would accept and hold it. Can someone confirm if a filter is needed on a 2006 Denali?

2. I saw where a clogged/cheap oil filter can send similar symptoms and might be a $10 fix verses the difficult, more expensive sensor.

3. Replace the sensor again - or check for security of install and wire harness.

Thanks in advance!
