Basically this P0101 diagnostic trouble code (DTC) means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not within a predetermined expected range of the calculated MAF value. Note: Some MAF sensors also...
A problem with the air flow sensor could also alter the shifting pattern of the automatic transmission.When the air flow sensor signal varies from the expected range, the PCM records a fault and stores the corresponding trouble code, illuminating the Check Engine light on the dash. This trouble...
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles that have a mass airflow sensor. Brands include but are not limited to Toyota, Infiniti, Nissan, Jaguar, Audi, Mercedes, Dodge, Hyundai, Chevy, Ford, etc. Although ...
Often, a dirty or faulty MAF sensor will cause the engine to set a LEAN code and turn on the Check Engine Light. If the MAF sensor wire becomes dirty or is contaminated with oil (from an aftermarket reusable air filter), it will be slow to react to changes in airflow. This may caus...
It is possible that a reset needs to be done in your car with a scanner to erase the old trouble codes and check if any of the codes persist. Do not use octane booster products. It is known that those products may cause harm to sensitive electronic fuel injection systems sensors ...

Potential causes for this trouble code may include:Dirty or contaminated mass air flow sensor Failed MAF sensor Intake air leaks MAF sensor electrical harness or wiring problem (open, shorted, frayed, poor connection, etc.)Note that other codes may be present if you have a P0104. You may ...
