This is a total noob question, but how do you check error codes that are thrown? I see a number of post here talking about error codes that they are seeing coming in from the MAF sensor and what not. Is there some type of diagnostic tool for max? If so, where do you get it? And can you change chip settings?

Peace.

 

odb II u can check out ebay

 

The ones on ebay are going to run about $50, those only display the code #, if you want a bit more involved/interactive unit, then you going to need to buy the $150 unit.

Or go to Autozone to get the codes checked for free.
