The P2195 diagnostic trouble code indicates that the oxygen sensor (O2 sensor) located on Bank 1 Sensor 1 is reporting a constantly lean condition.

In simple terms, the engine control module (ECM) believes the engine is running with too much air and not enough fuel, or the sensor itself is malfunctioning.

When P2195 appears, your Check Engine Light will illuminate, and you may notice rough idle, poor acceleration, or reduced fuel efficiency.

This is a common code on modern fuel-injected engines and often appears together with other fuel-trim or airflow-related codes.

The P0420 diagnostic trouble code indicates that the catalytic converter on Bank 1 is not operating efficiently.

In simple terms, this means the catalytic converter is not properly reducing harmful exhaust emissions.

When the P0420 code appears, your Check Engine Light will turn on.
In most cases, the vehicle may still drive normally, but the issue should not be ignored.

P0420 is one of the most common emissions-related trouble codes worldwide.

The P0101 diagnostic trouble code indicates that the engine control module (ECM) has detected an issue with the Mass Air Flow (MAF) sensor performance.

This means the MAF sensor readings are outside the expected range compared to engine load, throttle position, and RPM.

When the P0101 code appears, your Check Engine Light will turn on, and the vehicle may experience reduced performance, rough idle, or poor fuel economy.

P0101 is one of the most common airflow-related OBD2 trouble codes worldwide.
