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.

Hi!!
What all this codes have in common is that every single one of them can be caused by a vacuum leak, so carefully check for cracked, loose or disconnected vacuum hoses, wiring to the coils, fuel pressure regulator, fuel injectors, specially on cylinder 2.

  • PO100 - Possible causes are wiring harness failure, air leak or defective hot film MAF sensor
  • PO130 - Vacuum leak
  • PO170 - PO173 - Possible causes are air ingress (leak), fuel injector failure, pressure regulator failure or mechanical wear of engine. Inspect and repair as necessary.
  • PO300 - possible causes are vacuum leak, wiring harness failure or ignition coil defective.
  • PO302 - If limit value for misfire "harmful to TWC" is exceeded, the MIL flashes immediately. If too many combustion misfires occur in one cylinder, the cylinder is switched off (cylinder selective fuel shut off). After the affected cylinders are shut off, the MIL changes from flashing to continuously lit until next time the engine is started. If combustion misfires are recognized, the fault code P0460 or P0462 is set if fuel tank level is too low (fuel reserve indicator light is on). Combustion misfires due to a shortage of fuel are recognized by means of this additional information.

NOTE:After cylinder cut-out system is turned off, the system monitors (through misfire detection) if all intake and exhaust valves are open again.
NOTE:Misfiring may be caused by many faults in the fuel injection system. Usually a misfiring fault is stored with faults pertaining to other components. An engine mechanical fault could also cause a misfire condition.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Where can the blower heater be located


the blower motor for the heat and air conditioner is located underneath the glove box on the 97 e420
behind a plastic panel. it's easy to get to, but more than likely its the blower regulator thats defective
there is a solution to this problem without having to replace the whole unit which can cost up to $800.00. there is an s-class regulator that you put on the fan motor that will make it blow simply by
splicing a few wires. there is a company in cal. that sells the regulator for under $100. bucks can't
think of it right now but look up the regulator for e420 and you may get redirected to the site. drmack
