P0100 OBD-II Trouble Code

Technical Description

Mass Air Flow (MAF) Circuit Malfunction

Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.

You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness.
Causes

A code P0100 may mean one or more of the following:

* The MAF may be disconnected, or a wiring connection may be bad.
* The MAF sensor may be faulty.

Possible Solutions

Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back.
Then start with the cheapest, easiest repair procedures:

* Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires.
* Unplug and reconnect the MAF wiring harness a few times to clear the contacts.
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information).
* Replace the MAF sensor.

SOURCE: 04 mazda 6 lean condition

sounds like you have a vacuum leak. It is sucking in extra air from somewhere. possibly the intake manifold gaskets. The extra air coming in fools the computer / o2 sensors to believe it has a lean mixture then it will try to compensate for the lean mixture and add more fuel.

9 times out of 10 your problem is going to to be with the MAF Sensor. You changed it, was the old one bad? If not try putting the old one back in. If you bought an aftermarket MAF and didn't replace with an OEM MAF, that could also be your problem. Recheck to make sure it's seated correctly, check the wire connection.
Unless the stickers have been removed, you should have a vacuum line diagram under your hood.
Here are what you should check from top to bottom.
  • A clogged, stuck, or leaking fuel injector
  • Faulty fuel regulator
  • Dirty or faulty mass air flow sensor
  • Faulty coolant temperature sensor
  • Faulty thermostat
  • ECM needs reprogramming
  • Dirty or faulty oxygen sensor
  • Vacuum leak
  • Fuel delivery problem
  • Incorrect fuel pressure

Cylinders 4, 5 & 6 misfire. Lean bank 2 sensor 1 code and a mass air flow circuit code. 2003 Mazda Tribute V6. It was running fine then poof it was running rough. I am being told it may be a vacuum...


it is a regular fault
generally it is the Heated oxygen sensor (HO2S) in the exhaust manifold before the cat converter
other cause can include engine mechanical fault ( unlikely)---wiring---ignition / fuel system--injectors ---ECT/MAF sensor---ECM
a vacuum problem will affect both banks as will a PCV valve
The HO2S reads the exhaust gas composition and reports to the ECM which then adjusts the air /fuel ration accordingly to keep it within set parameters
The code says bank 2 sensor 1 which is the HO2S sensor so replace it and then have the codes read again

Code P2187


P2187 System Too Lean at Idle (Bank 1)

Check the MAF. this could be the reason for the O2 reading lean. if the MAF is ok and, the sensor is not damaged, replace the Os sensors.

No power with a 5.4 liter


P0171 and P0174 is a lean condition in your air/fuel ratio. This is common to a dirty MAF, IAT Sensor. You can buy a can of MAF sensor cleaner at Auto Zone or any other large auto parts store and just follow the instruction on the can. IF the reading from the MAF and IAT sensor's are incorrect, the PCM is thinking that the engine is getting to much gas so it's leaning the air/fule mixture out to much and your getting the dtc code for a lean mixture in your engine. That is causing you the lack of power since your not getting the right amount of air/fuel ratio in your engine which should be 14.7:1, anything more then that will be at a lean condition and prone to knocking (detonation) or miss fire. Good luck and hope this helps. keep me posted. be glad to help
