Default O2sensor

Thanks to who ever solved my VCM issue. Got the code 44 and fuel 44. Now what do I do with that? Is there a list of codes I can get?
thanks again

Hey. Ff 44 is oxygen sensor rich or lean. This can mean a vacuum leak making it lean, or a leaky injector making it rich- which seems unlikely. Go over your motor and check all the vacuum hoses. If your car is running fine and all you have is the code, it's probably the sensor. If you have uneven idle - surging or stumbling you likely have a vacuum leak.
