What does P0103 code mean?

Mass or Volume Air Flow Circuit High Input
OBD-II Code P0103 is defined as a Mass or Volume Air Flow Circuit High Input. The Mass Airflow Sensor (MAF) measures the amount of air entering the engine and the Engine Control Module (ECM) uses the information to determine the proper amount of fuel quantity and ignition timing.

What causes high voltage on MAF sensor?

Possible Causes: Intake air leaks. Dirty mass air flow sensor. Dirty mass air filter. Mass air flow sensor harness is open or shorted The MAF Sensor is unplugged or the wiring is damaged.

What causes mass or volume airflow circuit?

The mass airflow (MAF) sensor is a device that is mounted on the air intake. Its job is to measure the density and, therefore, the volume of filtered air that is drawn into the engine. When the PCM perceives the sensor or its circuit is malfunctioning, OBD-II code P0101 is triggered.

What does circuit high mean?

Diagnostic trouble code (DTC) P0463 stands for “Fuel Level Sensor “A” Circuit High.” It means that there is an unusually high voltage signal coming from your vehicle’s fuel sensor. The result is that the fuel gauge will not read accurately.

How much does it cost to fix a Mass airflow sensor?

MAF Sensor Replacement Cost The replacement cost of a mass air flow sensor can anywhere from $80 to $380. The cost of the part alone is about $30 to $300 with the lower end of the range for common aftermarket mass air flow sensors while higher quality or more complicated OEM sensors are more expensive.

What are the symptoms of a dirty mass air flow sensor?

Here are some of the most common symptoms of a faulty mass airflow sensor:

  • The engine is very hard to start or turn over.
  • The engine stalls shortly after starting.
  • The engine hesitates or drags while under load or idle.
  • Hesitation and jerking during acceleration.
  • The engine hiccups.
  • Excessively rich or lean idling.
