How do I fix the code po420?

Question

check engine light shows these two codes. the 420 I think I know where to start. The 113 code I could use some help on

Answer 1

The P0113 code is for a faulty intake air temp sensor. This is mounted to the air filter box at the throttle body. Most of the time the sensor wire inside burns up and causes the code, or it's not plugged in tight enough. Usually replacing the sensor will resolve the problem.
