This is a how to for the oil pressure sensor on NBS trucks. It's a common issue for it to go bad. My symptom was the oil pressure gauge pegged at 80 psi on my 2007 GMC Sierra Classic.

Parts: oil pressure sensor, GM 12616646, ACD D1846A, $34 on Amazon
oil pressure switch socket, Lisle 13250, $9 on Amazon

Here's the sensor. It's located on the block behind the intake manifold. Hard to get to, but I didn't have to remove the manifold like some have.

I used a u-joint socket with an extension and was able to get enough torque on it.

All finished. Be sure to tighten to 26 lb-ft.
