2001 vw cabrio ignition system sensor

Is someone really on here right now? is there any correlation between the ignition and the mass air flow sensor on a 2001 vw cabrio? here's the 441. i was naughty got a dui and had to have an interlock system installed to my car today. just had the car to the vw dealership 2wks ago, spent 4k, had the mass air flow sensor replaced and an all points check. This morning car in working condition. after they instaled this aparatus in my car this afternoon call is trying to turn over, stalling out and now REAKS of gasoline. i recognize this from my old volvo that i replaced the same sensor in (myself). i'm having the device removed tomorrow at 7am and taking to the dealership but would like some kind of information before he arrives tomorrow morning so any advice/information would be soooo appreciated. many thank you's in advance Denise :)

Mass air low sensors can be cleaned. If a new one was installed you should be ok as far as metering the air, sensor has very sensitive and fragile wires, and should only be cleaned by mass air flow sensor cleaner. Unless they left it unplugged, or the computer is not picking up signal from one dead out of the box. The all points check may have dislodged a vacuum line. But if you are at the dealer, they need to be answering your questions, after that 4K tune-up.

SOURCE: replacing mass air flow sensor in 97 vw jetta

If the mass flow sensor was bad, the check engine light should of came on giving off an engine code. To remove the mass flow, disconnect battery neg cable, then pull of the wire harness and pull out mass. You will probably have to remove the air intake hose.

SOURCE: My 2001 VW Beetle is stalling. I had a tune up

check engine light flashing means misfire and it staying on is probably because of your o2 sensor picking up all the unburnt fuel. check all the spark plugs again and make sure you didn't cross any wires. i'm pretty sure the wires were crossed or the spark plugs were fouled

SOURCE: Mechanic says I need to replace the mass air flow sensor

It should be in the airbox region so I would say quite easy.

03 Nissan Altima showing codes P0304,P0102,P0154,P0113 what are they and how do i repair the problems.


Hi Chris.

p0304 = Number 4 Cylinder Misfire Detected

Faulty spark plug 4
Clogged or faulty fuel injector 4
Faulty ignition coil 4
Fuel injector 4 harness is open or shorted
Fuel injector 4 circuit poor electrical connection
Ignition coil 4 harness is open or shorted
Ignition coil 4 circuit poor electrical connection
Insufficient cylinder 4 compression
Incorrect fuel pressure
Intake air leak

The P0304 code means that the cylinder 4 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 4.


p0102 = Mass or Volume Air Flow Circuit Low Input

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.


p0154 = O2 Sensor Circuit No Activity Detected Sensor 1 Bank 2

Faulty Front Heated Oxygen Sensor Bank 2
Front Heated Oxygen Sensor Bank 2 harness is open or shorted
Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
Inappropriate fuel pressure
Faulty fuel injectors
Intake air leaks may be faulty
Exhaust gas leaks

Replacing the Front Heated Oxygen Sensor Bank 2 usually takes care of the problem.


p0113 = Intake Air Temperature Sensor Circuit High

Faulty Intake Air Temperature (IAT) sensor
Dirty air filter
Intake Air Temperature (IAT) sensor harness is open or shorted
Intake Air Temperature (IAT) sensor circuit poor electrical connection

The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM).The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle.



Hope this helps

2001 Buick lesabre sometimes takes a few times to start other times will start right up and other times will start but when put in gear will die if you don't keep your foot on the gas


Could be several thing's . fuel system , ignition system . engine sensor etc... Instead of replacing a lot of parts that don't fix the problem ,take it to a qualified repair shop an have it diagnosed ! Because without testing no one on hear could say for sure it's this part or that part . There are videos on youtube for trouble shooting ignition systems , fuel systems , engine sensors etc... Sensors that could cause this problem , mass air flow , crankshaft position sensor - of which your vehicle has two .

    It does seem that there is a clogged injector. This causes the fuel to not atomize with the air thus not igniting thouroughly. But it could also be bad oil ring on pistons, or some bad valves. both of which dont always creat enough of a power loss or drag to notice. If an injector is the problem, use some seafoam fuel system cleaner, run it at max dose, and drive it like you stole it, see if that doesn't clear it up. One more thing you can check is if you have a mass air flow sensor, which I think you do, clean it with mass air flow sensor cleaner. Sometimes the wrong proportion of fuel is injected because the air flow readings are off. Good luck.

    I have an '02 VW Cabrio that is giving me random 171 and occasional 102 OBD codes. I looked for and found a split hose near the air filter housing and replaced. I've not found any others with...


    1st have you replaced the O2 sensor? Here is the technical stuff about this fault code
    OBD 2 fault code P0171 VOLKSWAGEN - Fuel control System To lean engine cylinder bank number #1.
    Possible causes:
    Possible causes- Intake air leaks, spray propane around the intake manifold gasket and all vacuum connections and listen for a change in the engine idle speeds, any change indicates a leak.
    - Faulty front heated oxygen sensor (a common cause if the car has over 50,000 miles on it)
    - Ignition misfiring
    - Faulty fuel injectors
    - Exhaust gas leaks
    - Incorrect fuel pressure Hook up a fuel gauge and make sure the fuel pressure is good/in specs under a load.
    - Faulty Mass Air Flow (MAF) sensor
    - Incorrect Positive Crankcase Ventilation (PCV) hose connection

    I get codes P0102 and P1128. My mechanic says I need to put a new mass air flow sensor on and it will take care of the problem. Is this correct?


    This could very well be correct I believe code P0102 is the mass airflow circuit low input. P1128 should be a lean code.

    I would first try cleaning your mass airflow sensor with a carb or throttle body cleaner, they have a tendency to get dirty and not read correctly.

    Want to know engine light p0102 code means


    P0102 is the generic DTC (Data Trouble Code) for (Mass or Volume Air Flow Circuit Low Input), and it would most likely be a fault with the MAF (Mass Air Flow) sensor.

    The MAF sensor could be dirty or faulty, and there might even be restricted air flow to the MAF sensor (like a plugged up air filter). Also be sure that there are no air or vacuum leaks in the air induction system especially between the MAF sensor and the throttle body and that the hose clamps on the air induction system are all tight.
