Description
OBD-II Trouble Code Description for P0101 Honda
Mass or Volume Air Flow Circuit Range/Performance
What does this mean?
OBD2 Code P0101 Honda definition:
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.
Symptoms
Possible sumptoms of OBD code P0101 Honda
You will likely not notice any serious drivability problems, although there may be symptoms.
Possible Solutions
The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures: Inspect for the following conditions: An incorrectly routed harness–Inspect the harness of the MAF sensor in order to verify that it is not routed too close to the following components: – The secondary ignition wires or coils – Any solenoids – Any relays – Any motors A low minimum air rate through the sensor bore may cause this DTC to set at idle or during deceleration. Inspect for any vacuum leaks downstream of the MAF sensor. A wide open throttle (WOT) acceleration from a stop should cause the MAF sensor g/s display on the scan tool to increase rapidly. This increase should be from 6-12 g/s at idle to 230 g/s or more at the time of the 1-2 shift. If the increase is not observed, inspect for a restriction in the induction system or the exhaust system. The barometric pressure (BARO) that is used in order to calculate the predicted MAF value is initially based on the MAP sensor at key ON. When the engine is running the MAP sensor value is continually updated near WOT. A skewed MAP sensor will cause the calculated MAF value to be inaccurate. The value shown for the MAP sensor display varies with the altitude. With the ignition ON and the engine OFF, 103 kPa is the approximate value near sea level. This value will decrease by approximately 3 kPa for every 305 meters (1,000 feet) of altitude. A high resistance on the ground circuit of the MAP sensor can cause this DTC to set. Any loss of vacuum to the MAP sensor can cause this DTC to set. If you suspect the condition may be related to aftermarket accessories, refer to Checking Aftermarket Accessories in Wiring Systems.

Note:
1. The list of automotive Makes at the right edge of the screen. The currently selected ODB-ii codes is for the Honda makes.
2. Look up the other OBD II Trouble Codes, please use the search box. Enter the 5 character trouble codes in the search box and submit the search.
3. Don’t assume a particular OBD-II code means the same for other auto manufacturers as there are many makes specific codes in use.
4. If your OBD-II trouble codes are for a different car, select that vehicle series before searching for the diagnostic codes because not all OBD2 codes used by one manufacture are used by the other makes.
