519Mike Posted July 16, 2020 Report Share Posted July 16, 2020 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. Quote Link to comment Share on other sites More sharing options...
BodybyFisher Posted July 16, 2020 Report Share Posted July 16, 2020 It seems the bricklayer is a better mechanic than the guy who calls himself a mechanic! 😉 The title 'mechanic' is used loosely sometimes 😁 Quote Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
