I could use some help guys. Just brought the truck used with 83000 miles. I had read the codes when I bought them and just took the risk so now I just need help figuring out what I need to fix them. The pictures show the codes. Tell me if I’m wrong but I think I need a O2 sensor and a PCV valve. Not sure on the last one though. Thanks

 

Best thing is to google the codes and read the causes/fixes for each one. This is my go to site: https://www.obd-codes.com/

I have just answered the first two codes in another thread in the last 24 hours.
The last code 1016 tells me you have an EcoBoost Engine for that specific code to set.,.
. You cannot just guess what the code descriptions tell you by going from a few words on a Scanner Display.
Code 051B is a >circuit connection< issue rarely the Sensor.
Code 0135 is also an open Sensor Heater >circuit< rarely the Sensor. This one will affect the Fuel Trim on that bank because the Sensor will be lazy acting on cold starts and otherwise for signaling correct A/F ratios to the fuel injection on that bank.
Both harness wire or plug-up issues.
Code 1016 is a fault in the Waiste Gate Control or flow path between a Turbo output and Throttle body input. >>a leak causing a loss of Boost pressure being sensed causing the code. This one will affect engine power / driveability..
Therefore, testing to verify first, before replacing parts.
Scanners are not the end all for repairs but only a beginning system ID and often cause a waste of time and money without fully knowing what the code means and applying the effort pointed to. This is important to everyone who is trying to service their own vehicle.
Good luck.
