Check engine light is on and DTC P0101?

Hi,

As far as the code is concerned, it is related to the mass air flow sensor (MAF). The code can be set by a few things. For example, an engine vacuum leak, a wiring or connector issue, a failed MAF sensor, intake air temperature sensor, and so on.

I attached diagnostics below. However, before you jump into the diagnostics, I would remove and clean the MAF sensor. They make a special cleaner specifically for them.

Here is a link that shows how to service it:

The mass air flow sensor is located in the air filter box. See pic 1 below. The remaining pics are the diagnostics related to the code.

Let me know if this helps or if you have other questions.

Take care,

joe
