Code P0103 Nissan Description
The Mass Air Flow (MAF) sensor is placed in the stream of the intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM). 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 air flow by means of this current change. The Diagnostic Trouble Code (DTC) will be set when the ECM detects that the MAF Sensor Signal is more than the factory specifications.
What are the Possible Causes of the DTC P0103 Nissan?
- Dirty Air Filter
- Dirty Mass Air Flow (MAF) Sensor
- Intake air leaks
- Faulty Mass Air Flow Sensor
- Mass Air Flow Sensor harness is open or shorted
- Mass Air Flow Sensor circuit poor electrical connection
How to Fix the DTC P0103 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.
Code Tech Notes
Before replacing the Mass Air Flow (MAF) Sensor, try replacing the air filter and cleaning the Mass Air Flow Sensor with low compress air or Mass Air Flow Sensor Cleaner. Reset code and drive vehicle. If the code comes back, you must replace the Mass Air Flow Sensor to fix the problem.
