The MAF (Mass Air Flow) sensor is a very common problem with these along with the pickups. This isn't what you would call an inexpensive part. Definitely do some shopping before you buy one.

It's should be a simple remove and replace. Just make sure the engine is off. Also do not touch any of the filament wires on the sensor, just the plastic housing. Also after you install it drive the car for a little while (city speeds, cruising speeds and inbetween). That way the computer will be able to readjust its setting since it is a new sensor.

SOURCE: mass air flow sensor

The mass airflow sensor is very important...it uses tiny diodes mounted in the flow path of the incoming air to the throttle body in units called CFM. It sends that information to the engine computer and the program calculates the proper amount of fuel needed to mix with the volume of air coming in. It is vital to your car that this sensor is properly maintained. If it's diodes are allowed to get dirty such as by having a dirty air filter, then the readings it takes will be inaccurate and the cars' performance will suffer. If the diodes break, you will not be able to drive the car and a new sensor is expensive.
DO NOT buy into snake-oil products like MAF cleaner...it is an expensive gimmick plus spraying anything under pressure into the sensor can break the diode filaments, some of them are barely .010" thick. Just remove the sensor with the proper bit and carefully poor a stream of isopropyl alcohol (isohol, rubbing alcohol) over the diodes until they shine. Then rinse with water and let air dry.

SOURCE: 98 chevy suburban, code reads mass air flow sensor

Check the wire leads and clean them before reconnecting the wire leads. It wouldn't hurt also to clean the MAF sensor with MAF cleaner, the code your getting is most common to the high performance oil base filters like K&N.

Good luck and this should help you resolve your MAF issues. Thank you for using Fixya

Hi Eric-
The air mass sensor may be either the wrong part or a faulty sensor. I would recommend trying another sensor. In addition please inspect the connector and make sure it is ok.

The engine runs rough and periodically stalls upon engagement, not while in P or N. Spark plugs, wires, ignition coils, and the module have all been replaced to no avail. Last week we took it to a mechanic...


Try unplugging the mass air flow sensor or tapping on it when it is running and listen for idle changes.The mass air flow sensor is located on top of the throttle body and is a rectangle held in place by tamper proof torx screws.If you unplug this the engine light will come on but if it stays running while driving then you can be pretty certain this is causing a problem.

If you clear the codes and the MAF code is generated again, AND the connector is OK to the MAF, then replace the MAF. Also, be sure your air filter is ok and the air horn (air flow tubing) from the air filter housing to the throttle body is securely connected and has no cracks in the rubber. If ok, replace the MAF sensor.

Stalling Toyota Camry 2004


P-0102 and P-0113 are mass air flow and intake air temp codes, the P-0136 is an Oxygen sensor code. Before you do anything, check for debris in the Mass Air Flow Sensor, it's small black box with electrical wiring connector that is screwed into the intake air tube, between the air box and the intake manifold. Undo the screws, remove the sensor, and, with a flashlight, and look down inside it for debeis, or broken wires inside it. If it's dirty, it could throw a P-0136...Comment back on what you find; hope this helps, and thanks for choosing FixYa!
