Engine Oil Pressure Sensor DIY

Recommended Posts

  • P0523 - Engine Oil Pressure Sensor/Switch Circuit High Voltage . 2010 Escalade EXT . I'm not sure why the mechanic took off the so many engine parts including the intake manifold on my buddy's truck to change this part . 
  • I took off a couple vent hoses to give my hand more room . I bought a oil pressure sensor socket . It took me under 20 minutes to change the oil pressure sensor and the drop in screen . Engine light is finally off 
  • I am a Bricklayer, not an Auto Mechanic/Technician. Is there a reason a Technician took off my buddy's intake manifold to change this sensor ? It cost him $500 more than the way I did it.

It seems the bricklayer is a better mechanic than the guy who calls himself a mechanic!  😉   The title 'mechanic' is used loosely sometimes 😁
