  • The PCM doesn't even see the O2 sensor until engine temp has reached operating temp,the vehicle goes from open loop when cold,to closed loop when warm,where the PCM uses the O2 sensor to measure the rich/lean of the exhaust content,and from that,adjust fuel richness to achieve 14.7 to 1 air/fuel ratio.So when cold,the O2 sensor is out of the picture anyways.When unplugging sensors,it can be deceitful.The PCM has a program whereas,if a critical sensor (such as the mass air flow) is somehow damaged and out of the picture,the PCM will substitue a generic value that will allow the engine to stay running.So,by unplugging the MAF,it did try to run on it's own better than plugged in,there's the problem area.The vehicle is running better with the MAF unplugged,because the MAF is likely bad,and the PCM is substituting it's generic value when it IS unplugged.Something to recheckThe PROM update is a newer program for the PCM,and likely won't fix it unless the PCM is bad.I would try a good used PCM as a last or later resort,because i have seen my fair share of defective PCM's too.I have taken some PCM's apart,and found capacitors that had gone bad and leaked all over the circuit board,mostly Honda and Mitsubishi and Chrysler though.Good luck,keep me posted.

Remove it and clean with some carb cleaner and a Q tip. Be careful with it so you don't do any damage. 9 of 10 times this will get you running again! Since signal from there is variable low voltage, you cant really bypass it!

SOURCE: Mass Air Flow problem

The M.A.S. is in the top of the metal tube between the air filter box and the intake manifold. It will have a wire connected to it and it is held in by 2 screws. This is an easy replacement and should take no more than 5 to 10 minutes, assuming you are taking your time.

yes your right. it is a low circuit input code for a mass air flow sensor. you can try taking the mass air off and cleaning it good. sometimes it will help but normally they are just bad.

P0101


Here is the definition of the code.

P0101 GMC Description The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM).

The temperature of the hot film is controlled by the ECM acertain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change.
Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection

My 2005 Sante Fe hesitates and won't get up to speed whenever it is damp or rainy outside. What causes this? Thanks


It could be your MAF (Mass Air Flow) sensor. Do you have any SEL {Service Engine) light coming on?

A mass air flow sensor is used to find out the mass of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature, altitude and use of a turbocharger and this is an ideal application for a mass sensor. (See stoichiometry and ideal gas law.)
There are two common types of mass airflow sensors in usage on automotive engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with an additional sensor or two, the engine's air mass flow rate can be accurately determined.
Both approaches are used almost exclusively on electronic fuel injection (EFI) engines. Both sensor designs output a 0.0- 5.0 volt or a pulse-width modulation (PWM) signal that is proportional to the air mass flow rate, and both sensors have an intake air temperature (IAT) sensor incorporated into their housings.
When a MAF is used in conjunction with an oxygen sensor, the engine's air/fuel ratio can be controlled very accurately. The MAF sensor provides the open-loop predicted air flow information (the measured air flow) to the ECU, and the oxygen sensor provides closed-loop feedback in order to make minor corrections to the predicted air mass.

Hello. I can assist you. Generally when a scan is done, the technician will clear out all of the codes and hope that the problem self corrects. I am glad you passed the state emissions test. Now let's get to the bottom of the hesitation. Generally all lincoln and ford cars that hesitate like yours have a problem with the "mass airflow sensor". Most likely you will need to replace it.
The Air Flow Sensor or Mass Airflow Sensor (MAF) is one of the components of an electronic fuel injection system and is found in many of modern vehicles. The Mass Air Flow sensor is usually installed inside the intake air duct between the air filter and the engine. The Mass Air Flow sensor is used to measure the amount of air entering the engine. This measurement is used by the engine computer or ECM to calculate proper amount of fuel injected into the cylinders in order to provide optimum combustion and low emissions.
Problems with Mass Air Flow sensors are common. Bad or contaminated Mass Air Flow sensor can possibly cause a wide range of various vehicle driveability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc.
In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.
The "check engine" or "service engine soon" light comes on when the engine computer detects some fault in one of the components of the emission control system.

Where is mass air flow senser on a 1989 buick regal


Hi

Thanks for using FixYa. The BUICK Regal Mass Air Flow sensor is usually installed in the intake air duct between the air filter and the throttle body mounted on the intake manifold. Also check the throttle body for mass air flow sensors location.
On mass air flow sensors with a sense wire, this wire can become contaminated with dust particles. These particles can be removed with automotive solvents that are safe for the use on mass air flow sensors. Before replacing the mass air flow sensor check for air leaks in the connecting air ducts and intake manifold. These leaks can cause similar symptoms as a malfunctioning mass air flow sensor.

Bad or contaminated BUICK Regal Mass Air Flow sensor can possibly cause a wide range of various vehicle drivability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc. In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

My check engine light came on and the code came back saying that the mass air flow sensor was out. All I did was change the air filter even though I really didn't think it needed it, the light went off and has not come back on yet. Knock on wood!

I have never heard of a knock sensor, the engine light on is usually do to a fuel air problem such has o2 sensors gas caps not sealing right or mass air flow sensors, the a/c problem sounds like if there are no leaks in system then your high low sensors one of them could have failed or your system froze up and needs to thaw if it froze let sit you will see a puddle of water on ground passenger side under vehicle close to engine this is from the evaporator if it froze up it will not allow air flow to go through it therefore you will get only heat turn heater on this will help thaw the evaporator quicker this freezing is usually due to an overcharged system or a system that is contaminated and needs flushed vacuemed and recharged.
