Question about 2003 Toyota Corolla

1 Answer

Toyota MAF There is no provision for the heated wire that you were inquiring about. I did not think so, but I did check for you. Nissan was famous for that idea "back in the day". Our MAFs are just the air temp sensor & the resistors for the air volume. Extremly small units, indeed. It may be of interest to you that the Corollas and the Celicas are the main candidates for our P-0171 discussion, Tacomas far fewer, and Camry/Avalon bringing up the rear. Seems as thought the snaller the engine, the more apt they are to the P-0171. Interesting,

    My work car is a 93 Camry, V6/5 speed. It too has the hydraulic cooling fans!

    They were not offered for very long.

    Interesting setup.

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

The wires going to the plug that goes in the maf sensor on my 96 Nissan pathfinder are cut in two. can they be spliced or should they be replaced in order for maf to work?if replace CAN SOMEONE WALK ME...

Why would you think wires can't be soldered
& heat shrunk?

Where would you get other wires anyway !

Have to cut them off at a salvage yard & then
still have the splice & solder thing to do

When i starte the my pathfinder 1998 the enigen is shaking not working smoth . thank you

This is the same engine in the Mercury Villager and Nissan Quest. First step is to clean the Mass AIr Flow sensor on the big air intake tube. Remove the MAF with 2 screws and spray the short heated wires with carb cleaner. Do not otuch, they are sensitive. Dirty makes a lean mixture.
Then go to our website, Yahoo gorup villager-quest and read our All About files.

I think it is\villager-quest. but google it.

clean the MAF sensor in the air intake. Spray the heated wires inside the MAF sensor with MAF cleaner or carb cleaner. Do not touch them. If coated with varnish, could be running lean.

1988 300zx turbo-automatic has intermittent sputtering. sometimes when cold in town and more recently with highway driving. Drove like 70 miles at 75 and sputtering started. Had mechanic check it out...

The famous MAF (mass airflow sensor) yours is a vane movement type this is the famous intermittent failure, here is the good new just adjust it. you dont have to relace it, the way to do it is to open the blaack cover and tension down the spring, (just a tad) this is the one of the solution. 300 zx has a proor ground problem to the MAF the fix and the solution is to get the MAF gound sensor and make a addition ground bolt it to the intake and your done. On the MAF sensor it the 3rd wire MAF ground NOT THE MAF ECM NEGATIVE connection

Nissan dealer says that I need to replace my MAF Sensor - should they be trying to clean it prior to replacing it?

dealers do not clean the MAF sensor heated wire, there is no way they can guarantee that it will permanently fix the problem, why don't you clean it? u can buy the cleaner from any parts store
