Default low oil pressure...problem?

I got a 4.9 300 I6 auto and lately i have notice my oil pressure is semi low. The guage has "normal" Written on it and it is usually at the N in "normal" is that bad? If so what could be the problem? This week i am going to run codes and seafoam...any advice is good. Thanks

Mine always showed low. I changed the oil pressure sensor and it was better but dropped back down later. Seafoamed and it's higher again but dropping back down again. I'm pretty sure the sensor gets clogged up. By the way, this is also my second engine which gives the same gauge readings. The old one died a non-oil related death.

Looooong time since I did it manually, but I hook up my reader, turn the key to "on", then press "Test" on my reader. So try turning the key to "On", then jumper the connectors.
