It says to Check the air flow - Hitachi CP-X251 LCD Projector

Something is wrong with that part of your car!

Have to look up the specs

In general you need about 16 oz (Volume) in 15 to 20 seconds

P0103 - Mass or Volume Air Flow Circuit High Input

Possible causes- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks
- Faulty mass air flow sensor

P0101 ISUZU - Mass Air Flow Circuit Performancehttp://engine-codes.com/p0101_isuzu.htmlForum CodePossible causes- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks
- Faulty mass air flow sensor
Tech notes Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor

P0103 HYUNDAI - Mass or Volume Air Flow Circuit High InputPossible causes- Dirty mass air flow sensor

- Mass air flow sensor electrical circuit poor connection
- Intake air leaks
- Faulty mass air flow sensor

P0112 HYUNDAI - Intake Air Temperature Sensor 1 Circuit Low InputPossible causes- Dirty air filter
- Intake air temperature (IAT) sensor harness is open or shorted
- Intake air temperature (IAT) sensor electrical circuit poor connection
- Faulty intake air temperature sensor
When is the code detected?An excessively low voltage from the sensor is sent to ECM.

check evaporator fan,prob just a bad run cap.

There are 3 likely possibilities:

1. Bad heater motor - a dead heater motor means no air flow
   
2. Disconnected or hole in air flow hose - sometimes a vent hose will dislodge just enough to disrupt air flow. Check underneath the inside of the passenger compartment for any loose hose connections. You can also turn the heat (or vent) on HI and check the air flow hose for any pinholes that also could disrupt your air flow
3. Bad Control Center - if the Control Center is bad, it won't trigger the heater motor to turn on and push air
   

Hi

Thanks for using FixYa. The BUICK Regal Mass Air Flow sensor is usually installed in the intake air duct between the air filter and the throttle body mounted on the intake manifold. Also check the throttle body for mass air flow sensors location.
On mass air flow sensors with a sense wire, this wire can become contaminated with dust particles. These particles can be removed with automotive solvents that are safe for the use on mass air flow sensors. Before replacing the mass air flow sensor check for air leaks in the connecting air ducts and intake manifold. These leaks can cause similar symptoms as a malfunctioning mass air flow sensor.

Bad or contaminated BUICK Regal Mass Air Flow sensor can possibly cause a wide range of various vehicle drivability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc. In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

I always first check the air flow. Turn the dryer on and check the air flow outside at the vent. If your not sure what a good air flow would be then disconnect the vent hose at the dryer and feel the air flow at the dryer and compair to the outside.

If the air flow on the outside is not what it should be then a leaf blower hooked to the inside vent hose will clear it out.

Good air flow, then I put an oven thermometer at the dryer air discharge to check the temp.

It should cycle between 100 - 150 degrees, if not, then let me know what it's reading

The Service Manual says:

E02D05 Airflow fan error
Fan rotation could not be detected while the air flowfan as running.

Probable problem locations
Air flow fan, engine controller, system controller

Remedy
1. Cable connection check (check - replace
2. Replace air flow fan
3. Replace engine controller
4. Replace system controller


I wish success
