Both codes refer to Mass Airflow sensor , Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. Unplug and reconnect the MAF wiring harness Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information) Replace the MAF sensor

Trouble codes


Technical DescriptionMass Air Flow (MAF) Circuit Low Input
What does that mean?Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.

SymptomsYou will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.
CausesA code P0102 may mean that one or more of the following has happened:
  • The MAF may be disconnected, or a wiring connection may be bad
  • The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
  • The MAF sensor may be faulty
  • The vehicle computer may be faulty (very rare)

P0101


Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not within a predetermined range of the calculated MAF value for more than 4.0 seconds. Other MAF sensor circuit DTC trouble codes are P0100, P0102, P0103, and P0104.

2001 mustang with code P0104 the scanner says that EGR flow


P0104 code is MAF or VAF. This can cause surging and rough running. If you disconnect the maf and find that it runs a little better, you can be sure that a maf replacement is in order. Double check the code by erasing it then roadtest. If code comes back then it is a hard code.
