Code p0101 p0101 code mass or volume air flow and circuuit

SOURCE: mass air flow sensor

maf sensors identify the amount of air flow flowing in the intake. the sensor works with the throttle so it knows how much air is coming in to add the proper amount of fuel to mix with the air. Easy to pull and replace.

SOURCE: 1997 nissan sentra, scan code reads p0100/ mass or

you may havta replace the air flow meter module.

SOURCE: I have a 2002 Nissan frontier SC, 69000 miles. Motor runs well when first start the engine and runs very routh after warm up and it just stops sudenly the engine. Three codes P0328(knock sensor 1 circ

P0328 Is knock sensor code,all Nissan have this code so leave,concentrate on P0101 and P0103 this is MAF(mass airflow),Just make sure the timing belt is in good condition and the marks are correct, your solution is NTB02-003A In other word you need a reprogram on the ECM

SOURCE: can't find mass volume air flow circuit high input

The P0113 code is the Intake Air Temperature Circuit High Input. This can be caused by a faulty MAF sensor, or by a problem with the wiring harness that connects to it. Check the harness first and make sure that none of the wires are broken or disconnected from the wiring clip.

The P0103 code is the Mass air flow sensor circuit high input. Since the IAT sensor is built in to the MAF sensor, it makes sense that you are getting both codes. Once again, inspect the wiring harness to the MAF sensor for damage or broken/disconnected wires.

If none of the wires are broken, you will have to do a little work to diagnose the issue, which could either be an open or shorted circuit, or a defective MAF sensor.

I have included the relevant pages from the manual.

CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage
to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
