Question about 2001 Mercedes-Benz C-Class

1 Answer

I cant I have a C230 '98. I just recently replaced the mass air flow sensor and I was driving with a broken one for a few months. Now the check engine light is off but the car lunges forward sometimes when its cold when it switches to second gear. Sometimes its one sometimes its more lunges...like the air gets sucked out of it n it loses power for a milli second. That's what it seems like. Is that the tranny itsself or a lesser problem like trans fluid or something?

Try removing the positive battery terminal for 10 mins then putting it back on, drive it around for a while after that and see if the problem disappears. When you were driving with a bad MAF sensor it may have adjusted your A/F ratio's to this and now with the new sensor it's trying to adjust in the same fashion it did with the bad MAF. Removing power should reset the ECU back to default corrections, it's worth a shot.

    Mass Air Flow Sensor Circuit High Input
  • Possible causes
  • Faulty mass air flow sensor
    - Intake air leaks
    - Dirty mass air flow sensor
    - Dirty mass air filter
    - Mass air flow sensor harness is open or shorted
    - Mass air flow sensor circuit poor electrical connection
  • Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.
  • possible symptoms Engine Light ON (or Service Engine Soon Warning Light)

have vechicle code scan, faulty mass air flow sensor will cause engine run poorly stall out.sound like transmission could be slipping not going in over drive if vechicle cant go over 40 miles an hour.change transmission fluid and filter see it helps. mass air flow sensor has to be replaced most people try clean them but best to replace them.

I got the code from the OBD IT read a code of 23 and one of 36 now i need to find what it means


code 23 is MAT too low.(mass air temp.) code 36 is Mass Air Flow Sensor Error

The ECM receives a signal from the Mass Air Flow sensor depending on the amount of air entering the engine. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.

Fault Code Description

  • 36 - Mass Air Flow sensor error

    Symptoms

    • Engine stalling
    • Lack of power

    Common Problems Faulty Mass Air Flow sensor,Broken wire to Mass Air Flow sensor,Dirty sensing element in Mass Air Flow sensor

      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.

      Runs rough when cruising at 35-40 mph


      try pulling off the air breather hose and look inside at the mass air flow sensor,it looks like a wire with a diode hooked to it incase you didnt know,see if there is any fuzz on it,sometimes the air filter will lose small pieces and the mass air flow sensor catches it.If that doesnt work then you may have a fuel problem,weak pressure,causing the mass air flow sensor to read too much air so it tricks the computer to adjust the issue.
