So my car has a bunch of codes p02017 p0301 p2004 p o506 I’ve already replaced the spark plug and tested the plug on p301 but the code still shows up so I’m just starting to work on the p0506 problem which is the idle air control and that pet has been replaced too so my next go to is replacing the power steering switch but I can’t find if anyone can tell me where it is I’d really appreciate it
