Where can I find the trouble code on my air flow sensor?
When the air flow sensor signal varies from the expected range, the PCM records a fault and stores the corresponding trouble code, illuminating the Check Engine light on the dash. This trouble code can be retrieved with a scan tool. The following trouble codes are usually associated with a mass air flow sensor:
Why is my air flow sensor out of range?
Sometimes a poor electrical connection at the air flow sensor connector could also cause the air flow readings to be out of range. For this reason, the air flow sensor connector terminals as well as the wiring needs to be carefully inspected.

What can cause a Mazda air flow sensor to fail?
For example, in some Mazda Skyactiv engines, a failed mass air flow sensor could cause the engine to crank but not to start. An improperly installed or collapsed air filter can cause the air flow sensor to fail sooner. Over-soaking a washable air filter can also cause troubles with the air flow sensor.

What is the code for the diesel intake air flow sensor?
P02E9 – Diesel Intake Air Flow Position Sensor Circuit High Trouble Code Fault Location Probable Cause P02E9 Diesel Intake Air Flow Position Sensor C Wiring, IAF Position Sensor, PCM
What is the OBD II fault code for diesel?
OBD II fault code P02E9 is a generic code that is defined as “Diesel Intake Air Flow Position Sensor Circuit High”, or sometimes, and depending on the manufacturer, as “Intake Air Flap Control Actuator Position Sensor – Circuit High”.
What is fault code for Mercedes Benz mass air flow?
As confirmation for faulty Mass Air Flow meter is fault code “P0101 – Mass or Air Flow Volume Sensor Circuit Range/Performance”, if it shows this fault it is definitely that MAF has failed. As the P0101 trouble code relates to internal damage, there’s not much that can be done at the roadside to solve the issue.
OBD II fault code P02E9 is a generic code that is defined as “Diesel Intake Air Flow Position Sensor Circuit High”, or sometimes, and depending on the manufacturer, as “Intake Air Flap Control Actuator Position Sensor – Circuit High”.
What are the symptoms of a bad air flow sensor?
The symptoms of a bad mass air flow sensor include low engine power, poor fuel economy, an engine that won’t start, a check engine light on the dash and a gas smell from the exhaust fumes. A bad mass air flow sensor is often the likely culprit if your car isn’t running as it should.
What are error codes for mass air flow sensor?
For doing so you only need to connect your code reader and turn the ignition key on (engine off), a state usually known as KOEO. Common error codes include P0299 (if turbocharger is fitted), P0300, P0101, P0102 and P0171.
