Went to install my intake last night, got everything in and together, started up the car and it idled just fine. Backed it out of the garage, put it in drive and had no throttle response. I was only able to coast. I did some research and tried replacing the fuse, cleaning the battery terminals and took the K&N intake out and replaced it back to stock. Still no change and still have the check engine light on.

Any help or advice? I'll continue searching, just hoping someone will have some advice. Thanks

SE, LE?

Sorry, just realized I forgot the important info:

2007 SE V6
about 65,000 miles

Lol, its all good bro.

When you say intake, do you mean the whole freakin assembly, or just the filter? LOL.

Actually the important info is/are the code(s) that originally set the CEL. Do you know them?

 

[cavy2camry]

I don't know any of the codes and don't know how I would get those since I can't drive it up to get it scanned.

I had the stock air box out of the car, new intake installed and now have the stock air box back in.


I did move the throttle body valve while installing it since I tried cleaning the throttle body if that makes a difference

When you cleaned the throttle body was the key inside in the ON Position? If so you most likely broke the throttle body. If not do not worry about that.

Most likely you have left either the MAF or another connector unplugged.

The MAF sensor is located on the air box and is attached with 2 screws. You are supposed to unplug it when removing the air box and intake. If you didn't unplug it you may hve broken the connector or pulled out wiring.

Likely you just left something unplugged. Make sure you have no dangling/damaged electrical connectors and that your air box is fully seated closed (2GRFE air boxes on Camrys are a huge pain to get back on right.)

I take it you either had someone hold the accelerator pedal down or propped it open with the key on while you cleaned the "valve." If you manually opened the valve, you probably screwed up the throttle positioning sensor and or the motor drive that acctuates the valve. I checked my tb several weeks ago and found very little to clean after 51,000 miles. I had to use two bricks to keep the tb open with the key on. When I started the car, it idled very fast and I noticed the AT shifted abnormaly for about 30 minutes of town and country driving before the idle and shifting become normal. The check engine light was also illuminated which required lifting the battery ground for a few minutes to clear.I can only guess that holding the tb open that far caused the ECM to sense a problem and illuminate the check engine light. Hope you didn't trash your tb. They are very expensive. Regards

Thanks for the help so far. When I opened the butterfly valve on the TB, the key was out of the ignition. I am starting to believe that I may have stripped the electric motor.

Hardtopte, I will double check to make sure I have a good seal on the airbox and everything, thanks

So are you saying you can open the throttle body while the key is off but not if the key is on? I can't dispute what you are saying since I have never seen the inside of the mortor/position sensor. Have other members manually opend the tb with the key off? Regards

 

[cavy2camry]

Yes, I accidently manually opened the TB yesterday. I just turned the key on and the butterfly valve opens on its own when pressing on the gas pedal but only once. When I press on the gas pedal a second time, it remains shut

 

[hardtopte72]

If the key is off you can open the throttle all day with no problems on DBW Toyotas (I have done this on HUNDREDS of Toyotas including all of mine with no issues). The problems stem from the key being in the ON position and you opening it manually. If the key was out of the ignition that is not your problem.

I can guarantee you have either something unplugged or something not on. Mind taking a picture of your engine bay near the intake too see if anything is off/wrong and posting it up?

I would bet its the MAF again. Without it your engine doesn't know how much air it's sucking in. If it doesn't know how much air it's sucking in it doesn't know how much fuel to add and wont fire the injectors more to accelerate. So no air=no fuel=no power or acceleration.

If however even for a second you opens the throttle with key in the ON position you may have damaged the throttle body.

As for it opening once that is normal. You will also find that on a 2GRFE when you or someone opens the throttle by stepping in the pedal that on this particular engine the throttle body barely opens. This makes cleaning it this way difficult. The best way is key off/manual opening on the motor.

Thanks, that's good to know I can open it with no problem with the key off.

Here are two pics I took. The MAF has been in and hooked up, all vacuum lines are connected. Like I said, the TB valve opens once with the key on and pressing on the gas, but after that it remains shut

Not sure what I did, but everything is fine now. I went out, unplugged the battery all together. Reconnected everything and ran like there was never a problem.
K&N intake is back in and running great....so far (knock on wood)

Thanks everyone for the help, I greatly appreciate it

 

[hardtopte72]

Glad everything worked out. Weird fluke. I have personally never unplugged the battery when cleaning the throttle. Maybe there was still some unevaporated throttle cleaner and it Couldn't rev. Who knows.

Does the oil coming off the K&N filter foul the MAF? I always wondered about that. Regards
