2009 suburban Ltz 1500 low oil pressure
Hey guys I need some help here 2009 suburban ltz 1500 with and lc9 sfi motor . The truck keeps Giving me a p0521 which is Engine oil pressure Sensor switch or performance. I replaced the sensor and cleaned the filter underneath it. also changed the oil and put a acdelco oil filter . Still getting same code . So i started searching and realized there is a sensor on the oil pan that is disconnected it's on the passenger side of the oil pan close towards the engine block looks like the oil level sensor but I asked the dealer they didn't know if this truck is even supposed to have this my question is,is this a stock part or did they change the pan and if it is stock would any one know where it goes connected it looks as if the wires were cut or ripped off?
