I installed an injen CAI on my 2000 max yesterday and today i got a check engine light, does that happen all the time you put an intake if anyone had the same problem please help.

Sorry if is a repost i cant search i'm in the job.
Help would be greatly appreciated.
Thanks

I pulled the code and it came to be p0505
which say "Idle system malfunction"
Well i took the car to a friend he is a nissan technician
and he say's that the car now needs a
"Throtle body".
The part with labor included is 850.

I forgot to post that before i installed the CAI i clean the throtle body and i guess thats how it got fukd up.
Any ideal?

 

usually intakes will give you check engine (SES) lights because the engine is getting more air and that amount isnt programmed into the computer. as long as the car is running fine your ok.

 

Yeah it's ok

 

why would you wanna drive around with the cel on.

 

The car is running nice its just that the light just bugs me.
What will happend will it get used to it?
Is it posible to use the cai as a ram anybody know because im scared to drive it if it rains

 

no i dont want to drive with a SES on so i'm worried and i want to know if thats normal.

 

No need to worry about rain, unless you're planning on driving through a foot or more of standing water. The plastic guard panel under the bumper protects the filter from water when it's raining.

I never got an SES light with my Injen on my 2k2. For your 2k, tou could try disconnecting the negative battery terminal overnight.

 

Huh? Where did you dig up this information. Had an injen for 6 months and I never had said problems.

Truth is, CAI should not set off a SES. Double check your breather hose and MAF connection, and go to Autozone and get the code pulled to see what it is. I think you will find it has nothing to do with the CAI.

 

Uuuuh..... no.

 

+1 on running the code check

 

alright guys thanks for the help i will let you know when i resolve the problem

 

You have to take a lot of things into consideration. I installed mine (also an injen CAI on my 00 maxima) and I never got any SES light. Did you run the car for about 10 minutes after installing it? This helps the car's ECU to adjust to the increase of airflow. Plus pull the codes using OBDII scanner and Im predicting it will be your MAF if you have not changed it before.
Let me know.

 

When i installed my injen, i got a cel for like 3-4 days then it went away. Car runs fine

 

No CEL with my InJen install. Go to Autozone and get back to us with the codes.

 

Anybody had the same problem?

 

You still have the problem? It's been a week and a half! Go here: www.autozone.com and look for the nearest location. They'll pull the codes and tell you what it is. It could be anything, but not likely to be the result of the Injen unless it's the MAF. (it's not the MAF or else your car wouldn't rev past 3500 rpms....)

 

Some cars may differ from others so it may take a little more time for the ECU to get adjusted to the new intake. Double check all your connections making sure that they are all secured including the vaccum hoses. Leaks could cause the alight to appear. Took mine several weeks for the light to go off. During that time it would appear then disappear only after long drives and/or if I really got the tach to move. Now it's off for good.

 

An Injen CAI will not make your ECU throw a code, you probably didnt make a tight fitting on the two mid-pipe emissions hoses. Recheck all your work, make sure you didnt leave anything unplugged like the MAF.

I can't imagine why "your mechanic" would want to rip you so bad, you dont need a "new" throttle body unless you ****ed yours up so bad that after cleaning its still sticky.

 

ok guys i did take it to autozone and the code was p0505 idle system malfunction and then i took it to friend in a nissan dealer he is the head technician and he is honest He said some how i **** up the throthle body so i need a new one any body had the same problem with the throthle body.

 

P0505 is an Idle Air Control Valve system fault code. You don't mean replace the whole TB assembly surely?

 

do the TB posistion reset proceedure. Check stickies. It should fix it. Stealerships at their finest....
