Code P0100 Nissan Description
The ECM controls the temperature of the hot film by a certain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the airflow by means of this current change.
The Diagnostic Trouble Code (DTC) will be set when a high voltage from the sensor is sent to ECM under light load driving conditions or a low voltage from the sensor is sent to ECM.
What are the Possible Causes of the DTC P0100 Nissan?
- Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor circuit poor electrical connection
How to Fix the DTC P0100 Nissan?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
