Also, check to ensure that all wiring is secure at its terminals within the sensor connector. You will now need to carefully inspect the wiring to and from your mass air flow sensor.Ĭheck for broken, frayed, or pinched wires. Step 2: Inspect MAF Sensor Wiring and Connector If other codes are present, you must consider the bigger picture, as it pertains to what your vehicles on-board diagnostic system is attempting to tell you. Step 1: Check For Additional Codesīefore beginning the diagnostic process, it is important to use an OBD2 compatible scan tool to see if any other fault codes are currently active.
The steps provided below will put you well on your way to uncovering the source of your vehicle’s current issue. This begins with following a series of diagnostic steps.
In order to rid your vehicle of its p0101 fault code, you must first determine the root cause that has caused the code to be set.
Inspect MAF Sensor Wiring and Connector. In the case of a p0101 error code, the engine management computer has determined that the feedback being presented by the mass airflow sensor is not within its typical operating range.Ĭheck out this article for more about a p0101 code. When the ECM receives feedback from the mass airflow sensor in regards to the amount of air entering the intake tract, this figure is used to make proper calculations pertaining to fuel delivery. The flow of air into the engine’s intake track is monitored by the mass airflow sensor and reported back to the engine computer. To better understand what this fault is indicating, you must first understand what a mass airflow sensor is, and how it works.Ī mass airflow sensor is typically found within an engine's intake tract, downstream of the air filter housing. This code is stating that there is an error within the mass airflow sensor circuit.Įssentially, your vehicle’s PCM (powertrain control module) has detected that the input that it has been given by the mass airflow sensor is incorrect. DTC p0101 is a mass airflow circuit range/performance fault.
