P0104 OBD-II Trouble Code
Mass Air Flow (MAF) Circuit Intermittent
What does that mean?
Basically this means that there is a problem with the Mass Air Flow High (MAF) sensor or circuit. A more technical description would be that the MAF is producing incorrect air flow readings. Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0102, and P0103.
You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.
A code P0104 may mean that one or more of the following has happened:
- The mass air flow (MAF) circuit is incomplete (broken / frayed wire, etc.)
- There is an air leak in the intake system
The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
- Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
- Inspect for any air leaks near the MAF sensor.
- Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
- Replace the MAF sensor.
