Where is the 2012 chevy silverado oil pressure sensor located?

The oil pressure sensor on the 2012 Chevy Silverado is located at the top rear of the engine under the intake manifold. Replacing the sensor is a relatively easy task that requires simple hand tools and an hour of time. The main purpose of the sensor is to watch the pressure of the oil as it is cycled through the engine, that way if the oil pressure drops, a warning light can be set off. If You receive a warning about low oil pressure, which is usually caused by not having enough oil, the first thing You need to do is stop the car on level ground and check the oil. If it is low, do not start the engine until You have added more oil.
