my engine light goes on when i engine break. my bro says it might b my intake, i got an ebay short ram intake on my b16. theres a hole on the tube where there might go a sensor or sumthing, we just put a plug on it cuz my engine doesnt have anything to plug in there. my bro says to put a stock b16 intake and it might fix the check engine light. should i change the intake or just look for vacuum leaks or sumthing? thanks guys, as always ur a great help

 

That hole it for a hose that goes onto an inlet on your valve cover, it's the breather tube.

Connect it. You should see a big unused metal tube sticking out about 1" from the back of your valve cover, that's where the hose goes.

 

thanks alot. i already have a tube going into my intake from my engine. but farther up theres another hole on the intake, idk wat for. so i just plugged it with a rubber thing.

 

the cold air intake has nothing to do with your cel you can run without an intake and not throw any codes, the second hole in the pipe is for 96-00 civics that have a sensor. what year is your car?

 

oh, my civic is 94. i didnt know wat the other hole was for, thanks for the info

 

make sure your intake air temperature sensor is plugged in

 

have you checked your check engline light yet??

 

Take a picture of it..

 

does the light go away by inself? or only happens when you engine brake ? does it go away when u give it gas? if so you got some thing grounding..

 

it only goes on when i engine brake. and doesnt go away unless i turn off and back on the car. the sensor is plugged in. i havent checked the engine light in a long time, im assuming its the same code as b4 but idk.
