Hello everyone, I have been away for a while and moved to Charlotte, NC. My car has been running good (with normal maintenance and replacements) until recently. My check engine light came on yesterday so I got my homemade scanner tool out and got the following codes:
Pin 3 - code 19: Fuel Injectors open/short circuit or self adaption in engine control module (N3/4) at limit;
Pin 3 - code 22: Camshaft position sensor signal defective;
Pin 8 - code 20: self adaption at idle speed or upper/lower partial load at rich or lean limit;

I was able to clear pin 8, code 20, but not pin 3 codes. The check engine light went off but later came back on.

I am not sure if all the codes are for the same problem?

A little history about my car - 205k miles, 4 years ago the wire harness was replaced (purchased from a long time member of this forum), the throttle body was replaced, the OVP, oxygen sensors, spark plugs, fan clutch. A couple months ago the water pump and fan bearing/housing were replaced. A week ago I sprayed some engine cleaner and water around the power steering pump in order to clear the NC safety inspection. The car currently runs good/smooth acceleration starts without hesitation.

Any help is much appreciated, Thank you.
