i have a 2003 Nissan Altima SE 3.5L and the check engine light is on and its giveing me p0103 code... what can i do?
Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
Possible causes:
- 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
