I searched first and found similar problems but nothing exact.

2006 with AEM cold air intake

I went through an automatic car wash earlier and now my check engine, trac off and vsc lights are on. Any ideas on what the problem may be? Am I gonna have to drive 40 miles to the dealer? Damn, I hope not! Thanks in advance for any help.

 

To start with check the filter, is it wet? remove it & dry it. Maybe figure out why it got wet. Clear the MIL (CEL) with a scanner or remove the efi fuse for a minute.
With code cleared & filter dry, test drive vehicle for a few miles, stop vehicle, remove key, then restart & drive back home, stop vehicle & remove key. Start vehicle one more time, is MIL (CEL) on, no, good!

 

Thanks, I'll try this tomorrow when I get home from work. I don't have a scanner to check the codes so I'll have to pull the fuse. If I do have to take it in, do I need to put the stock box air box back on first due to the warranty?

 

I would think you probably won't end up going to the dealer, but just take it as is.

 

Thanks alot!

 

Your MAF sensor may have gotten dirty... if the car is running, I wouldn't worry about it too much...

Try resetting the ECU, you may need to clean the MAF.

 

sounds like the maf got wet.. Sounds like your air intake was sucking water big time...install by pass valve to stop that....

 

disconnect the baterry on both post have it reset on its own..

 

You're lucky that the intake didn't suck up much water... avoid automatic carwashes with undercarriage spray. Mine got hit once too, had to shut the car off for 2 hours until the filter dried... coulda been way worse.

If it's an AEM, it has a bypass, but enough mist might've gotten in there to foul the MAF. You can get MAF cleaner at an auto parts store.

 

Thanks. I'll try cleaning the maf. It is an AEM. If that doesn't work, I'll try the reset.

 

If u have a A.E.M. air intake the bypass valve is a option..make usre u get one so u dont end up with the same problem again...be carefull to..just because u pull the fuse out and the light goes off..doesnt mean the code is still there..the code will still be in the ecu's memory..u need a scan tool to erase the hard code permentally from the memory...due to obdII standards...

 

Ok you have a DTC.

Instead of putting unnessecary effort into tring to fix a problem without knowing what it is, get the code retrieved.

If you get the code retreived I can tell you how to fix it, how to test the component, help you pinpoint the issue instead of just throwing parts and wasted money/time at it.

also just an FYI, an ECM reset on a toyota vehicle can be accomplished by pulling the EFI fuse, leaving it out for 5min. This supplies the power for the ECM.

 

Hey dbm,

Autozone will pull the trouble codes and clear them for free. That way you know what code you actually threw....must like Scorpius stated.

 

Thanks Leroy, I'll have them check the codes on Wednesday, I won't be driving it until then.

Scorpius, I will post the codes for you then. Thanks for the help everybody.

 

Scorpius, the code is P0012. The guy at Autozone said it was the camshaft sensor (maybe something similar). Thanks for the help.

 

read this thread !

Yeah, I have read a few threads in the past 30 minutes about the problem. I just set up an appointment at the dealership for Monday.
Do I need to put the stock airbox back on before I take it in?

 

to be on the safe side, yes...

 

Damn, I thought someone was going to say that.

 

That code looks familar.........too bad I do not live in your area I cannot tell you how many of these I have done .
I am sure you already know by now that it is the cam shaft gear, and there is a TSB on this. This is covered under the 5/60 month powertrain warranty. Good luck.
