Can A Malfunctioning Mass Airflow Sensor Cause The 2014 Nissan Pathfinder Check Engine Light To Come On, And How Can It Be Diagnosed And Repaired?

Yes, a malfunctioning mass airflow sensor can cause the 2014 Nissan Pathfinder check engine light to come on. The mass airflow sensor (MAF) is responsible for measuring the amount of air entering the engine, which helps the engine control module (ECM) adjust the fuel delivery and ignition timing. If the MAF is malfunctioning or sending incorrect signals, it can cause the engine to run lean or rich, resulting in decreased performance and increased emissions. This can trigger the 2014 Nissan Pathfinder check engine light to come on.

To diagnose a malfunctioning MAF sensor in a 2014 Nissan Pathfinder, a mechanic may use a scan tool to read the diagnostic trouble codes (DTCs) stored in the ECM. Common codes related to a malfunctioning MAF include P0101 (MAF circuit range/performance), P0102 (MAF circuit low input), and P0103 (MAF circuit high input). The mechanic may also inspect the MAF sensor for damage or contamination, as these can also cause issues with the sensor’s function.

If a malfunctioning MAF sensor is diagnosed as the cause of the 2014 Nissan Pathfinder check engine light, it can be repaired by replacing the sensor. The MAF sensor is located in the air intake system, typically near the air filter. Replacement involves removing the old sensor and installing a new one, then clearing the DTCs from the ECM with a scan tool.
