I have a 2010 Lincoln MKS Ecoboost 3.5L AWD and I having a couple of codes showing up ...
P0020, P0030,P0050,P0130, P0150, P052D ... I also already changed the two O2 sensors but still getting codes for the sensors. Need some help
Clear the codes and and see if they come back, if you have not already.
P0020 - check the wiring to the VCT solenoid on bank 2. May be a dirty connector or a pin pulled out of the connector, etc. Has been known to happen.
P0030 & P0050 - have you installed downpipes recently? Using any adapters? Are the new sensors Motorcraft? Any leaks in the exhaust system?
P052D - also related to the VCT solenoid. Should clear up if the P0020 clears up. If not, then replacing the solenoid is the likely solution.
To P0030 & P0050 the new sensors are motorcraft no new installation on downpipes.... p0020 what would be the best way to clean the connector ?
Disconnect the battery first. Liberally spray MAF Sensor Cleaner or Electrical Parts Cleaner into the connectors on both ends, solenoid and harness. Use a stiff toothbrush to clean off the pins. Spray some more cleaner for a final cleaning. A dab of dielectric grease on both connectors and seal back up.
My guess is a loose pin in the harness, that seems the most common issue with the SHO where VCT solenoids are concerned.
Since you have a 2010MY inspect the wiring for any chaffing or corrosion especially on the harness connector!
I believe the VCT solenoid is located right under the Battery tray IIRC! Z
