What does DTC p0101 mean on a car?
DTC p0101 is a mass airflow circuit range/performance fault. This code is stating that there is an error within the mass airflow sensor circuit. Essentially, your vehicle’s PCM (powertrain control module) has detected that the input that it has been given by the mass airflow sensor is incorrect.
When does the front O2 sensor Register p0171?
P0171 is triggered when the front O2 sensors recognize a lean mixture. It can both be a short-term lean mixture or a long-term lean mixture. If it’s a short-term lean mixture the fuel mixture is often very lean. If it’s a long-term mixture, it can register the code because of a small notice of lean mixture over time.
