OK, so i bought my Civic about 5 months ago... was changing the air filter and noticed a hole in the top airbox where the air filter goes (D17a Engine - Stock)... after some research i found that its where the IAT sensor goes. i have realized that this most probably is messing with my fuel consumption... but in the long term i have fears that my engine is just gonna die one day after breathing dirty air cos its an open hole!!!

What should my next step be to try prevent this? (car might have been driving without this for a while...)

AM I SCREWED OR IS THERE HOPE???

i'll be doing that...

can anyone give me a pic of where the wiring/pipe which connects to the sensor leads to, incase its just hanging around my engine bay.

the connector should be hanging in the bay somewhere. the sensor youre gonna have to buy unless its attached to the connector by some chance. should be near where the throttle body is cause that wire is not very long.

why didnt u check for somting to be wrong when u saw the check engine light on on the test drive? i would have said " buy a sensor and put it in. reset the light THEN i'll buy it. "

i mean the Engine light isnt on... and wasnt on when i test drove the car either

i bet the sensor is still plugged into the harness then and dangling in the engine bay near the air box. if it was not there, engine light would be on guaranteed.

those were my thoughts too...

but i cant see any connectors/sensor looking things in that area .
where does the wiring for the sensor start? from on top of the tapet cover?

Nevermind!! found it... was hiding underneath the rest of the harness wires. and its a small black thing (i was looking for it at night).

Thanks For help guys.

if it doesnt fit snug in the airbox, you need to get the rubber grommet ring to put in the airbox hole first.
