SOURCE: My car was diagnoised with a bad air flow sensor

the mass air flow sensor is located under the top plastic engine cover. to remove this un screw the oil filler tube by hand and remove the top cover. its just to the right of center engine. unplug this sensor. next it has two screws to take this off. It is not standard screws so look at it. remove them and replace sensor. After install go to autozone and have the warning code removed. This is done free. 2000 buick lesabre

SOURCE: P0102 code on a 2000 Buick Park Avenue

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.

It could be a dirty air filter a, spark plug, spark plug wires.
a leak in the air intake system or the mass air flow sensor

SOURCE: Where is the Mass Air Flow Sensor?

It is inline with the air intake .They are typically held in the tubing with hose clamps and a 2 or 3 wire connection. Make sure you check for direction of air flow.

SOURCE: I have a 1991 Buick Park Avenue. Runs rough in

Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

1996 gmc sierra 5.7L what would cause engine codes p0102, p0108, p0121,p0300 at same time?


p0102 is MAF mass air flow , circuit low input. Try these to reset code by trying following.
Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires. Inspect for any air leaks near the MAF sensor. Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor. Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information) Replace the MAF sensor.

Code p0102 in a 2001 Cadillac sts Seville northstar engine wat does it mean


Code p0102, according to:

P0102 Cadillac Mass or Volume Air Flow Circuit Low Input

is "Mass or Volume air Flow Circuit Low Input"
Means that the computer isn't getting enough signal from your MAF sensor.

Check the link above for more information. MAF replacement isn't difficult.

What is the meaning of Code P0102?


Code p0102 is for Mass Air Flow Sensor. What it is read this:-
A mass (air) flow sensor (MAF) is used to find out the mass flowrate 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 the use of forced induction, which means that mass flow sensors are more appropriate than volumetric flow sensors for determining the quantity of intake air in each cylinder. (Seestoichiometry and ideal gas law.)

There are two common types of mass airflow sensors in use on automotive engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with additional sensors and inputs, an engine's ECU can determine the mass flowrate of intake air.
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 for most post OBDII vehicles. Vehicles prior to 1996 could have MAF without an IAT. An example is 1994 Infiniti Q45.
When a MAF sensor 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 controller 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.

P0102 Chevrolet - Mass or Volume Air Flow Circuit Low Input

Read more: http://engine-codes.com/p0102_chevrolet.html#ixzz38p5k1ZD8

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.

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.

Higher octane gas 93 with some good octane boost in the black can at autozone cost about 7 dollars or a bottle of 104 octane boost. Change the fuel filter. Probably only one coil pack is bad. The OBDII reader should tell you which one was a misfire.

Service engine light


Good Day,

Code P0102 indicates MAF(Mass Air Flow) sensor circuit, low frequency detected

Code P0300 indicates Random Cylider miss fire, meaning missfire in more than one cylinder

The misfire could be a result of the mas air flow sensor being faulty.

Hope this helps for now

Let me know what size motor and if it's 2wd or 4wd and I can get detailed instructions for replacing
