I have a 01 tacoma and have put a cold air intake on, and my check engine light keeps coming on. The reader said that the intake is the problem in that it is getting too much air. How do I make that stupid light go off? Is there a diffrent air/flow sencer that I can put in? What can I do? Any help would be great.

The guy that helps me with the truck, has a reader and it is showing A/F problems and the A/F sencer ohms out ok. I am sure this not the first time this kind of thing has happened.

Have you gone back and checked for any leaks in the new intake? Are all the hoses hooked back up to the right places?

Yes all the hoses and every thing is where it susposed to be. My mechanic said it is getting to much air for the sencer. I was just checking to see if anybody had any ideas or suggestions on what to do other than putting back the factory aircleaner.

I can't see it getting too much air. I have an aftermarket intake on a 97 4Runner V6 with headers and exhaust with no problem. That moves quite a bit more air than stock. My friend has one on a 2K Tacoma 4 cyl with no problem. There are tons of these kits out there. There must be something else going on. What code are you getting exactly? Give us the actual numbers.

The code is P1130 and the possible trouble ares could be; open or short in A/F sensor circuit, A/F sensor, Air induction system, fuel pressure, injector, or ECM. I just asssumed that with the new air cleaner and the majority of the problems on the list are air/flow related.

u might need to take out the fuse for your ecu, leave it out for 15 minutes then put it back in

Yeah, take out the EFI fuse, the little 15amp one and not the big black one, for 15 minutes or so, replug it in and it should be OK.

Yeah, clear the computer first, then see if the code come back. If it does, check resistance at the connection to the ecu as well as at the afm to make sure the wiring is ok. Check again for leaks in the system.

How long have you had it on the truck? I've heard where some vehicles take a little time to "get use to" all the extra air and after a few weeks they are fine. Allthough I have not heard of this with a toyota.

I broke down and took it to a dealer, and they tested the air/flow sencer and it was bad. They showed me how to test it for the next time. Thanks everyone for all your help.

Thanks for posting the end result. Many times we never get to hear what the outcome was.

My understanding of OBDII which is most 1996 models and after, the only way to clear codes is with a reader. My manual confirms this. It will be interesting to see if pulling the fuse does anything. I haven't had any luck with that only using a reader to clear codes....

I didn't try that due to it being the F/A sencer. And where I come from if it ain't broke don't mess with it. Thanks for your input.
