I got a cel while driving in the rain yesterday and was wondering if i could have sucked up some water and possibly shorted the mafs or something cuz the code that they got at autozone said maf and vaf. he reset it and it came back on about and hour later.

thanks.

 

i have a fujita CAI and no inner fender, the 2 days i have driven in HARD RAIN i got a CEL, after it stopped raining it went away. (i turn on my trip meter whenever a CEL pops up) and it took 45 miles for the CEL to go away...

 

yeup.. happens to me.. uh happened today actually.. i think its because of the diameter of the piping of the cai and the moisture getting to the maf.. itll go away..

 

what does the cel light actually mean when it turns on

 

you shouldn't get a CEL from driving in the rain with a cold air intake.

i drive in the rain all the time with my trd CAI and never got a CEL. and i mean hard rain where the road looked like a freaking river.

something must be wrong with the CAI or your MAF or something, it shouldn't suck up any water.

as for what does CEL actually mean. it means that your engine has detected something wrong, and using a scangauge, it will give you an error code that will give you a general idea of what is wrong with the engine.

so get your engine scaned at the dealership or auto zone or whatever, see what is wrong.

 

so its just a general error

 

exactely, can be that your engine is running rich, your catlytic convertor has failed. you can even get a CEL if your gas cap wasn't screwed on tight enough.

 

my dad got a check engine light from a gas cap loose...and i laughed at him. cuz he took it in to get serviced and didnt have a work truck for a week(company truck btw)

 

lol, yeah. that's gotta be embarassing.

 

I think it is your intake. I have heard of CEL's appearing with the Fujita intakes on the tC.

 

u serious i wanted the fujita one too

 

it only happens when it rains..

 

guess it only happens to the fujita cai. haven't heard of this problem with any other CAI, and i've had the k&n typhoon 69 intake, and the trd cai.

 

yeah its only the fujita.. damn things always causing trouble lol
