well code 31 is for the AFM right? i thought i mentioned that before. anyways yeah i'm getting 31 and 32, but i have already ruled out 32. i know the HAC is not causing this problem. I know all the wiring is good because i have tested it right after the ecu pins and right at the AFM plug and...

yeah my voltmeter cant check hertz. if the truck just idles it wont throw a code, but when i try to rev it up a few times it will eventually die. When i restart it, it throws code 31 and goes into limp mode.

i believe it does but i will look. yeah i checked THA Vc and Ks right at the ecu and right at the AFM plug. they all measure 5 volts whether the engine is running or just the key is on. I will check into the hertz on my meter and see if they fluctuate at all

so just checked voltage right at the Ks pinout on the ecu. it always stays right at 5 volts whether the vehicle is running or not. should the voltage fluctuate while it is running? oh and the AFM was plugged in during all this testing.

thanks alot for all the info! i am not a wiring genius so it is a little harder for me to understand some of the testing i will need to do at the ecu. when you say to measure it "live" i'm assuming you mean to test it while the vehicle is running. So i need to find the Ks pinout at the ecu and...

i installed everything the exact same way it was. i unplugged the AFM and it runs the same with it unplugged. IDK what that is supposed to mean for sure. and yeah it sounds like a fuel cut at about 3000 rpm, i'm sure thats because of fail safe mode. unfortunately i do not know anyone in my...

yeah unfortunately it didnt help. I am at a total loss as to what is wrong with this turd. I still wish i had a known good AFM i could test. I'm not saying the one you sent me is bad, i'm just thinking it would be nice to install both of the AFM's on a running supra and see if they both work...

ok i will go through and test for shorts and continuity. i do not have another ecu. i did not clean the other sensor i bought. yes it is barely running..... here are the symptoms: I can start the vehicle and it will idle almost perfectly for a long time with no CEL. But as soon as i push on...

well i checked all the pins on the female side of the connector (side with the wiring connected to it) you told me to check Vc, Vs, E1. according to my Haynes manual mine has a Ks pin but no Vs pin. i'm assuming Ks is the same as Vs. Ks must be my signal pin. Looking at the connector my pins...

thanks man! i will get it figured out eventually, its just drivin me crazy right now

ok thats good to know, i will check tomorrow. also i dont believe the patched in piece is causing any problems. basically it looks like they might have broken the female plug that connects to the AFM, so they just wired in a new one. the wires are the same color and they are soldered together...

ok that makes more sense! that was the nest thing i want to check into, is how to check all the wiring going to the AFM. so the VC pin should have 12v to it? or just a power signal?

yeah i realize that now! lol but the weird thing is that i did buy an AFM from a guy on this forum, tryed it and i still have the same problem (code 31 and 32) it runs horrible and keeps dying. i cant even drive it because there is absolutely no power. I have tested both AFM's with the...

alright guys thanks alot for the info. I will do some more checking into the HAC sensor tomorrow. as far as testing VC goes, i have tested both AFM's with the ohmmeter multiple times and it seems to me that they are within spec

well the 7m torque is not treating me at all because the damn thing wont run worth a crap! i havnt even gotten to take it out and wheel it yet because i have done nothing but try to fix problems on it ever since i bought it. I cleaned out the AFM and replaced the air filter because they were...

yeah i see how it may be sending the wrong signal, but the vehicle was running just fine before i cleaned the AFM. then i put it back on and it immediately threw codes 31 and 32. so i figured i must have fried the AFM by cleaning it. So i got another one that is exactly the same as the one that...

i will get some shots of the engine bay later, i dont have any at the moment. and as far as the progress goes i will keep you guys updated!

also do you guys know if an AFM off an N/A 2jz will work for my 7mgte?

thanks for the info but i probly wont have those wires dangling down from behind the glovebox because this engine is in an 87 4runner, not a supra. I did trace out the wires on the AFM and it looks like they wired in a connector for a different AFM. about 18" from the AFM the wires are butt...

thanks alot for the great comments guys! i like this forum alot so far. there has been alot of nice welcomes and lots of good info right away about my AFM problem in the tech section. And as far as the dents and rollover marks goes, i have only had this rig for two weeks now! the guy i got it...
