Camry 1991-Air Flow Meter HELP - Toyota Nation Forum : Toyota Car and Truck Forums

My Camry ( 1991 LE) has the Engine Light ON. The test said code 25,26 - Air meter failed spec test for pinout resistance value. The mechanic said the Air Flow Meter need to be changed. The Air Flow Meter cost $900 (From dealer). Anyone has cheaper or quicker fix for this problem. Thanks.

First double check the female terminals in the connector;
Second pry open the plastic cover and resolder pins to the circuit board. Use electronic grade rosin core solder and 25 watts soldering iron with pointed tip.

The mechanic actually tested the AFM meter and is not guessing? Aftermarket parts are available (much cheaper). Try online parts sites like www.rockauto.com and your local auto parts stores.

I'll sell you one for $450... Just kidding, but they should be available at any wrecking yard for $25 to $50. As far as that goes one of the yards around here sells them for $8 each with the airbox and I actually have some spares since I've replaced the smaller 3sfe airbox with the larger 2vzfe airboxes on my Camrys for better filter surface area.

If you can't find one let me know, I might be willing to send one your way.

before you go replacing parts, make sure that you are replacing the correct parts

codes 25 and 26 refer to Air-Fuel Ratios being too lean and/or too rich. Chances are, your O2 sensor is what's malfunctioning, and is a MUCH cheaper fix than a $900 AFM.

Thanks, Do you know if they have the code for O2 sensor ? Can I find the code meaning for this car online some where ?
Thanks for all the helps people ...

Your original post said that the mechanic told you that you had CEL codes 25 and 26. Unless you were present when he tested the AFM itself, he may have just told you thats what the problem was. But, a faulty O2 sensor can also register simultaneous CEL codes 25 and 26.

Now, unless you know that the O2 sensor has already been replaced at least once in it's 17 years of life, chances are it needs to be replaced.

BTW: it might be b/c I wasn't doing it correctly, but when i tried to get resistance readouts from my AFM, it took me at least 20 tries.

also, there's a sticky on the gen 1/2 forumn for the camry manuals. CEL codes are in the emissions section

You're obsolutely right. I took my car to another mechanic and he only changed the O2 sensor and the problem was fixed. Cost $130 (Part+Labor).
Thanks again.

you're right! i did mine myself. took me 1/2 an hour. It would've been quicker had i known that heat makes PB Blaster work almost instantly. But, you can't fault him for goin to a mech. Some people don't have the time or the know how to work on their own cars.

Before i replaced the alternator on my car, the only thing i did on my own was oil change, and brakes. Everything else, i went to either Toyota or nearby Mech. When Toyota, told me that an alternator plus labor was goin to be $400+, i said screw that, i'll figure it out myself!!!

well...not myself...i had help from this board

Ever since, then, I've done most of the work on my car myself.
