Does anyone know where the oil pressure sensor or switch is located. I just replaced my water pump and radiator on 2007 Aspen 5.7 hemi, drove the truck few blocks oil light blinks on and off then stays on. I drove it back home, not sure what is wrong, thinking i might have knocked something loose by accident

 

Replaced mine recently(2007 5.7 Hemi) . Sensor is just above the oil filter. I think the code was P0524. Check out YouTube for some good videos to help with this easy installation..
Good luck.
