Should in the air intake tube right behind the air filter. usually a square box. Should have 4 small bolts and be easily removable with common tools. ( usually torx headed bolt) When removed it will look like 2 small posts with a little ceramic piece connectting the posts. Usually has trash on it, keeping it from reading the air passing by it. It may just need to be cleaned with compressed air instead of replaced. After you clean it clear the code ( im sure thats whats maken you think its bad) and put it back in. If the code comes back, replace it. GL
Have you looked under the hood?
