P0103 PONTIAC code

P0103 is the code for a problem with the Mass Airflow (MAF) Sensor having a high voltage output to the Engine Control Unit (ECU).

How do I fix error code P0103?

Zitat von Youtube: You can spray the maf sensor cleaner onto the wire perpendicularly to the ground so that it won't damage the maf sensor reinstall the maf sensor back in the car after it gets dry.

What causes a P0103 code?

Code P0103 is set when the Powertrain Control Module detects a high voltage output from the MAF Sensor. A vehicle with this code should be taken in to a repair shop for diagnosis.

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.

How do I reset my mass airflow sensor?

Upon replacing the Mass Air Flow Sensor, turn on the engine light to ensure it still has its function. You can unhook the battery and leave it unhooked for 10 minutes to completely reset the entire system. The battery will not harm itself if left unhooked for more than 10 minutes.

How do you test a MAF sensor?

Zitat von Youtube: Use clasp if you have to all right next we want to get our test lead and start testing these pins on the harness side the harness side being the side that's not coming from your MAF sensor.

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 is mass air flow circuit?

In a vehicle, the mass airflow (MAF) sensor measures the amount of air going into the engine through the intake. The powertrain control module (PCM) then uses that information to calculate how much fuel should be delivered to the engine.

What is a volume air flow sensor?

There are two main types of air flow sensors: volume air flow sensors, which measure the effect of moving air on a pinwheel or deflecting plate, and mass air flow sensors, which measure the mass of air as it passes through the sensor.

What is mean of circuit high?

“Fuel Level Sensor “A” Circuit High” refers to the Diagnostic Trouble Code (DTC) P0463. When this occurs, your vehicle’s fuel sensor will be sending an unusually high voltage signal. A faulty fuel gauge can cause it to take an inaccurate reading.

How do you fix the engine code P0101?
