It will turn itself off if no further problems are detected in the next few ignition cycles.

Hello all. I just replaced the oil pressure sensor on my wife's 2006 Yukon (5.3 engine). I was able to replace with only removing the plastic intake cover and the air intake (from air cleaner to throttle body). This required loosening three 5/16 screws (one on intake cover and two clamps on air intake) and four screws (air cleaner cover). These were removed to ensure they weren't cracked as I laid across engine to reach back of engine on the drivers side (right side) to remove the sensor. Location is directly under firewall before back of engine meets the transmission. I used a 3/4" drive, two 6" 3/4" extensions, swivel, and a Autozone Oil pressure sensor socket #25254 to remove the sensor. I will try and add pictures for location and to show what I removed. Took 15min max. Hopefully this will help!
Pictures as promised:
