What does dirty mass air flow sensor code mean?
A common cause for lean condition codes is simply a dirty Mass Air Flow Sensor. Since I have been testing MAF sensors, I thought I should bring up this information.

What kind of air flow sensor do I need for my MAF?
Depending on the year and make of the vehicle, you may find different types of mass air flow sensors, from the old-style vane air flow meter to the modern era hot-wire mass air flow meter. Since hot-wire technology is the most widely used today, we’ll assume that your MAF is using that design.
Why is the O2 sensor no activity in bank 1?
If there is no response from the O2 sensor for Bank1, Sensor, no response indicates that there is no change of voltage between 410 to 490 mV for over 74 seconds (from the fuel enrichment signals or fuel cut off as signaled by the ECM). The possibility of the ECM not working well inside the 02 circuits.
When does air bypass the mass airflow sensor?
In this scenario air bypasses the flow sensing element and you get a lean condition.Here’s another situation where the mass airflow sensor gets bypassed. It’s when the air duct that runs from the air filter housing assembly to the throttle body is torn. This is a common condition on older, high mileage vehicles.
Can a dirty mass airflow sensor be a problem?
Thus, symptoms and false trouble codes indicating a sensor failure are likely. If there is no vacuum leaks and the air induction hose is in good shape, it’s possible that a dirty mass airflow sensor is the problem. This can display the same problems and symptoms as a defective part.
What happens when the MAF sensor goes bad?
If the MAF sensor has gone bad, it’ll trigger the check engine light and provide an OBDII trouble code. This is great because it helps you narrow down the problem. The two most common trouble codes in relation to the MAF sensor are: There are other codes related to the mass air flow sensor as well, but these are the most common ones.
What is the code for the air temperature sensor?
P0111 Code: Intake Air Temperature Sensor 1 Circuit Range / Performance (Bank 1) P0071 Code: Ambient Air Temperature Sensor Range/Performance P0073 Code: Ambient Air Temperature Sensor Circuit High
