For my maf to clean it up w/ brake cleaner have to remov the all piece o just the sensor i mean the full piece where the sensor is placed

A code P0102 may mean that one or more of the following has happened: The MAF may be disconnected, or a wiring connection may be bad The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF). The MAF sensor may be faulty The vehicle computer may be faulty (very rare) Possible Solutions The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures: 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.

Autozone, carquest ect. sell MAF sensor cleaner. Do not touch the sensor because it will most likely break. Pull the throttle body off and spray it down with the MAF cleaner. Brake cleaner is supposed to work but cannot verify that in all vehicles and sometimes carb clean will work depending on the vehicle.

Hi there:
This means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow).

Possible Solutions

The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:

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.

Replace the MAF sensor.

Hope helps.

p0103 is maf sensor A high input. ( manifold air flow ).

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. you can buy maf sensor cleaner at any auto parts store. follow directions on back of maf sensor cleaner. clean sensor first this may solve problem. good- luck!! do not touch inside of sensor with the straw from the can or anything else, just spray it and let dry, then put back on car.

P0171 system too lean bank 1
P0174 system too lean bank 2
links to information on the codes

it means that the O2 sensors in your vehicle detected a lean condition in their respective banks. this could be caused by a dirty MAF (mass air flow) sensor or a vacuum leak downstream from the MAF sensor

sometimes you can clean the MAF with electronics cleaner or brake cleaner but be sure to take it off the vehicle first. be careful not to damage the MAF while spraying the cleaner, and allow it to dry completely before installing it on the vehicle.

P0103 - Mass Air Flow (MAF) Circuit High Input
Basically this means that there is a problem with the Mass Air Flow High (MAF) sensor or circuit. A more technical description would be that the MAF circuit had higher than expected voltage (air flow). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0102, and P0104.

Symptoms: You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes: A code P0103 may mean that one or more of the following has happened:
* The MAF may be disconnected, or a wiring connection may be bad
* The MAF sensor may be damaged
* The vehicle computer may be faulty (very rare)

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* 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.

Check it and tell us news.

Check the air filter , and clean inside the throttle body, behind the plate. also clean the mass air flow sensor in the air filer tube. use brake clean.Let me know we'll go from there

system too lean(bank 1). the maff sensor may be dirty or bad. to clean it , remove from vehicle and go to any auto parts store and buy a can of maff sensor spray. be very carefull not to touch inside of sensor, the best way to do it is to place on a clean rag and then clean it. put back on car when dry. this usually does the trick. Inspect all vacuum lines and the vacuum line from pcv valve. also make sure airfilter is clean and free of dust. if above does not solve problem, check fuel filter. hope this helps, follow directions on can to clean maff sensor.

You first remove the wiring connector, and then remove the 2 screws that holds the MAF in place. Remove the MAF, and, with a flashlight, look down into the bottom of the sensor. You will see 2 small silver wires, and a little bulb. The MAF part is the 2 wires. The intake air temperature sensor is the samll 'bulb'. Look to see if the 2 wires are fuxxy, or otherwise dirty. If so: using a can of commonly obtained "brake cleaner" (find this product at any auto parts store), spray the interior of the MAF until the 2 silver wires are clean. Please do NOT use compressed air to clean the MAF, the air pressure can and will brake the wires, and that will render the MAF inoperative. After it is cleaned, let it air-dry, and then replace it and reconnect it. Drive the vehicle for a few miles for the computer to see the new values.
