Here I demonstrate the simple steps involved with cleaning your mass airflow sensor. In this particular case I was troubleshooting a rough idle on a 2006 Chevy Colorado 3.5, but these steps can work for almost any vehicle. If you have any questions feel free to post them and I will do my best to help!

Here are some of the codes you might see related to your MAF:
P0100 Mass or Volume Air Flow Circuit Malfunction
P0101 Mass or Volume Air Flow Circuit Range/Performance Problem
P0102 Mass or Volume Air Flow Circuit Low Input
P0103 Mass or Volume Air Flow Circuit High Input
P0104 Mass or Volume Air Flow Circuit Intermittent

P0171 System too Lean (Bank 1)
P0172 System too Rich (Bank 1)
P0174 System too Lean (Bank 2)
P0175 System too Rich (Bank 2)
