Sup im new to the forums and some what new to playing with my baby (car) I'm in the process of learning to work on my car. I just put on a new cold air intake using the same factory air sensor that was on the box intake i popped it out of the old one and into the new intake and now I'm getting a check engine light and the code it's throwing is the air intake. What is this issue and how do I fix it?

 

Some cold air intakes require a tune since more air is being seen by the MAF than the factory intake. So you will either need a tuner or buy a bigger MAF.

 

How careful were you swapping it over? Those IAT sensors are sensitive.

 

Did you disconnect the battery before you swapped out the intake? This resets the computers. Without a reset the computer would see an immediate difference coming from the sensor before/after the intake swap and throw an error code. Try disconnecting the battery for 15 minutes or so before spending any money.
