Engine Light...randomly go on and off

KraziAzn · 02-08-2008, 01:34 PM

yah...

i got my K&N intake installed yesterday...and after that...the engine light would go on and off...

randomly....

any idea what i should do??

Ct_Sidan07 · 02-08-2008, 01:40 PM

reset the ecu by unconnecting the negative wire (black wire) on the battery...do this for a few minutes and the problem should go away

I'm guessing that the sensor might either be put on wrong or it came loose, try adjusting it a bit see if it helps?

alrite im not too good with cars...

how would i adjust it? do i just unscrew it and screw it back on??

that simple?

that could work, could of come loose or something, disconnect your battery's negative also for like 20 sec and put it back on and it should be off (CEL).

did that.. CEL went off for about 30 miles...and came back on...

i should probably get it checked out?

My guess is that there is an air leak. Make sure all of your connections are tight.

**Gonzo** · 02-15-2008, 12:18 AM

How often does it go on and off? How much time between those intervals?
If it is going on and off fairly rapidly (more often than twice in an hour) that is pretty odd.

As the guy above suggested, check all your hoses, make sure they are tight, and check your wiring to make sure it is all secure. Also check the seating of your maf sensor. Be sure it is sitting flat and the o-ring on it isn't pinched or anything.

Did you mess with anything else than installing the intake that day?

1. It stays on... it never turns off

2. the hose that connected to the engine...is not ziped tie... but i check its out pretty tight

3. I got a local shop to install.

**Gonzo** · 02-15-2008, 12:59 AM

I would make sure you get some clips for all the hose on both ends.

The shape and size of the oem clips are designed so they pinch the tubes and hoses right behind the lip or flange of where they connect.

Zip ties I don't know that I would suggest. They are more narrow than clips and they don't really provide pressure in the same way a spring clip does. Plus zip ties aren't really reusable and I would imagine are more susceptible to failure.

Just my two cents.

Hope everything gets settled. If you find out what the problem was be sure to post it. Good luck!

KraziAzn · 02-15-2008, 03:09 AM

alrite thnxs..ill buy some clips later this week see how it goes

echamsou · 02-15-2008, 02:07 PM

i got same problem with CEL it randomly goes on and off, usualy i noticed when it`s warm outside it`s on, and when it`s wet and cold (around -10C) outside and air is humid, the light sometimes goes off. was wondering if there`s any way to get a code readings.

Adlh29 · 02-15-2008, 05:54 PM

Try a Scangauge2

BlackSi10 · 02-15-2008, 06:35 PM

take it up to auto zone and they will check it for free and tell you what it says

**Gonzo** · 02-15-2008, 07:11 PM

Yeah, lots of auto part stores will scan your car for you. Autozone and Advance definitely will. Pep Boys probably would to (bleh...)

There is a pretty unlikely chance the scanner may not know what the code means. Some scanners know lots of codes and will display the name and meaning, but crappy scanners won't display the meaning or might now know the meaning for manufacturer specific codes. In that case it will still display the actual code which you can write down and look up later online.

and i checked the hoses again...i found out i was missing 2 clamps! omg i feel so dumb...

but yah i went to autozone today...lawl...and but clamps...now im gonna resetting the ECU as i type?

so ill update u guys in a bit

HondaTune · 02-18-2008, 09:49 PM

Wow..... Im just keeping up w/ this thread to see if anyone here will finally guess it..

This is sooo easy lol, blah.

heres the the HINT.

what happends to a obd2 car when you disconnect the MAS - Mass Airflow Sensor lol....

If that doesnt give it away then .

ok nvm ill stop being a dick, Clearly the "shop" that did it for you are some un-legit bastard that didn't clear the code.

When you disconenct the Mass Airflow Sensor or (MAS) You will throw a check engine light. Also you will throw a check engine light if there is a air leak ANYWHERE in the breather or so..

But most likely since the "shop" hopefully knows how to install a intake, then its just the MAS code that needs to be cleared.

If your broke come over here to cali to my school ill clear the code for ya, Good luck. Let me know what happnds
