So the codes are 21-main o2 sensor 24-maf sensor?? 28-main o2 sensor 31-maf sensor??
if my maf sensor is broken wouldn't it be fking up my o2 sensors as well?? are these codes all connected somehow?? could it also be my iacv?? i had idling and stalling problems about a month ago so i cleaned my iacv and it ran great for 1 month. now today my car starting idling high on cold start ups and sometimes it stays at a high idle and usually when its at normal operating temp, the rpm starts to drop until eventually it hits zero and stalls. I have a feeling all these codes have to do with one another or is my ecu fk up. help please. anyone have extra parts for sale??
I just got the following codes (mechanic told me during a service): 24 - Air intake temp sensor open or shorted for more than 0.5 sec. 31 - No AFM signal for 2 sec or engine stall.
So these may be old, so everything was reset and I want to check these myself.
Will these codes show on the EMV running a system diagnostic? (currently I have no error codes)
Are these codes linked?
Where is the air temp sensor? I have found posts about replacing it with a resistor, but where is it?
What is the part number and what is the price? I am having problems locating it on Toyo DIY, I found the AFM, but no temp sensor.

michael i believe the air temp sensor is on the maf sensor. so yes in a way they are linked. I have the same problem but after resetting the ecu im not able to pull any codes but the cel is on when the car is running. im thinking it's my ecu.
