What to do if your car has a p0100 fault code?
Have a certified technician verify the code with a scanner. Reset the fault codes and perform a road test. If the P0100 code comes back, then follow the test procedure. Inspect the electrical connector to insure it is attached. Disconnect it and then reinstall to ensure fresh electrical connection. Repair any…
Why is my car not accelerating at all?
It is in those situations that drivers will come to notice the obvious slow acceleration and the fact that the engine of their vehicle is struggling to keep up.

Why is my air flow sensor not working?
Since the function of the air flow sensor is to measure air mass that is flowing into air intake, a clogged or bad mass air flow sensor could send the wrong data to the engine ECU for calculating the air fuel mixture. A very symptom of an air flow meter malfunction is car that won’t accelerate correctly.
How does the throttle position sensor ( TPS ) work?
The basic principle of the throttle position sensor (TPS) is to detect the throttle valve opening angle which is controlled by accelerator pedal. Then the TPS will send this data to the ECU.
What does a p0100 diagnostic trouble code mean?
This P0100 diagnostic trouble code (DTC) means that there is a detected problem with the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not performing within the normal expected range of the calculated MAF value.
What does p0100 mean on a MAF circuit?
P0101 Mass or Volume Air Flow “A” Circuit Range/Performance P0102 Mass or Volume Air Flow “A” Circuit Low Input P0103 Mass or Volume Air Flow “A” Circuit High Input P0104 Mass or Volume Air Flow “A” Circuit Intermittent Photo of a MAF sensor:
What are the symptoms of a bad throttle position sensor?
This is another failure mode of the TPS, which indicates that it is falsely limiting the power being requested with your accelerator pedal foot. You may find that your car will accelerate, but not beyond a speed of 20 – 30 MPH. This symptom often goes hand in hand with loss-of-power behavior.
What does DTC stand for in Powertrain Control Module?
The powertrain control module (PCM) uses that reading along with other sensor parameters to ensure proper fuel delivery at any given time for optimum power and fuel efficiency. This P0100 diagnostic trouble code (DTC) means that there is a detected problem with the Mass Air Flow (MAF) sensor or circuit.
