Pushed the Max to Auto Zone yesterday and...
I guess after months of my CEL being on my car made it clear to me something is wrong with it. After it cut off on me I went to auto zone to get the diagnosis. It came back with P0140(02 sensor) and two P0100 codes one for the MAF sensor and the other for the knock sensor. Is there anything I could try before I spend $300 on new parts?
man those codes will pop up on you that dosent mean anything is wrong with the sensors after i did my ground cables and alternator rewire i havent had a problem since the fluctuation of voltage to PCM and sensors will set of the CEL light everytime i also cut the MAF ground wire and mounted a new ground right next to the strut tower and havent had any problem since

But, the KS is oftentimes triggered by the O2. So, change the O2 sensor, and the KS might go away.
(i round up the the nearest hundred, lol)
anyways...
to help out LILMAN, i know there is a way to test the knock sensor with an ohmeter, not exactly sure how to though. Can the other sensors be tested in a similar manner (i woud assume so)?

I think a Haynes or Chilton Manual is a good investment.

I'll check the voltage, and go from there. Good lookin out.
BTW Whats the part number for O2 2 Bank 1?
test? ok test your knock sensor but you cant test it under load unless your on a dyno so thats out the question bad 02 sensor yea maybe but i dont see how that would set off MAF and knock codes from what i was syaing earlier try the Alternator rewire and ground mod then cut your MAF ground and make a seperate ground for close as possible i had the exact same 3 codes come on but since those mods no problems
