SOURCE: WHERE IS THE MAF AND VAF LOCATED ON A 2001 6 CYL

the MAF is usually located on the snorkel ( hose connecting the air box to the throttle body) should be closer to the air box. 4-5 wire connector. square shaped. clean with brake parts cleaner or carb cleaner, something that evaporates fast. sometimes cleaning it works but not always.not sure on the vaf. Hope this helps

SOURCE: service engine soon light, code

The Volume Airflow (VAF) / Mass Air Flow (MAF) / Intake Air Temperature (IAT) sensor is located on the air intake housing tube inlet.

Your code is P0102 - Mass Air Flow (MAF) Circuit Low Input, them basically 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). Other MAF sensor circuit DTC trouble codes are P0100, P0101, P0103, and P0104.

Fig. Identifying mass air flow sensor connector-3.5L, 3.8L, 3.9L and 5.3L engines

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 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.


Then, like a reference guide check this TSB DTC P0102 MAF and this article about Mass Air Flow sensor, what does it do and how it does it.
Test, check it and keep us updated.

Abotu Oxygen Sensor - O2 codes, will need look some code as P0420 in your OBD II codes reader to check O2 sensor wiring for damage from resting on exhaust pipe or frayed wiring.

Hope this helps.

I have a '11 Toyota Camry LE, the VSC, and engine light are on. I have these codes from the local auto parts shop: C1201, P0171, and P0101.


code p 101 refers to mass air flow(MAF)sensor/volume air flow(VAF) sensor --range performance problem====causes --intake leak/blockage---MAF/VAF sensor

code p 0171 refers to system to lean bank 1===causes ---intake /exhaust leak---AIR system---MAF/VAF sensor ---fuel pressure/pump---injector/s---HO2S ( heated oxygen sensor --the one in the exhaust manifold before the cat converter bank 1)

I don't have a listing for the c code but from the other 2 codes I would be checking around the maf/vaf sensors and the HO2S sensor (replace)
start with checking the wiring and connections to both units

96 Caprice 5.7 lt1 throwing P0100. Book says maf or vaf malfunction.I no maf is mass air flow not vaf nor where either are located and if different performance test to determine which one 2 replace.


both are located in the air flow of the intake. VAF is vain air flow meter. you will only have the MAF sensor. VAF sensors are usually only on cars made in Europe like Volkswagen.

What is code p0101/p0300/p0171


code p0101 refers to MAF sensor and VAF sensor--range /performance problems===causes --intake leakage/blockage ---MAF/VAF sensor failure.

code p0300 refers to random misfires multiple cylinders ---causes --spark plugs /HT leads --injector /s-- ignition coil/ s--low compression ---wiring

check fuel pressure in manifold and HT leads

code p0171 refers to system too lean bank 1 ===causes --intake /exhaust air leak---AIR system---MAF/VAF sensors ---fuel pressure /pump---injectors ---HO2S sensor

Basically there are two codes referring to the MAF/VAF sensors so check them out and two codes referring to fuel pressure and pump so have a pressure test done on the fuel manifold to determine if pump or pressure regulator.

05 cobalt manual oil pumped clogged up, engine almost ran dry. replaced oil and filter and few days later engine started pinging. kinda moderate when idling then very rapid while driving. Wanna do the


pinging is from spontaneous combustion ( detonation) and is from incorrect air /fuel ration and ignition timing. Run fault codes and check knock sensor and MAF/MAP/VAF sensors . Left un- checked it will melt holes in the pistons.
