Hey guys, not sure is this is the right forum, however,

As those from western sydney know right now, the rain is terrential at the moment and i took my eyes off the road for a second on a dim back street and went through a pretty solid puddle at 60km/h

after coming out of the puddle, the engine sputtered a bit and seemed jolty and i could tell by the exhaust something wasnt right, as it started popping and cracking a touch.

after about 20 seconds of driving though the check engine light came on but the engine was running as normal.

The check engine light is still on even though it seems fine, what should i do?

Thanks in advance,

Matt

Are you running a cold air intake? Maybe some water got sucked in?

yeah i am, i think i may have sucked a touch in but do you think i did harm?

matthew, dont worry about it, the sensors are a bit touchy about getting wet, it`ll clear itself.
try doing half a dozen ignition ons, that should reset it.

Dont worry about it. I did the same, RHS was quite deep in water and left side was no water. I went through it at around 80kmh/s. Threw a sensor something about an intake manifold or something. I cleared it and hasn't come back.

Good work pete ^

It was raining today and i was sure i was gunna get a warning light with all the water and the CAI

just take off and then put back on the negative of your battery, resets it straight away

lol, pete parrots me and timmy says good work pete, whats with that timmy?

U would have picked up a bit of water, i did the same thing on the way down to melbourne with Steve (good times) mine cleared ok after a restart and mine was close to dieing. The water upsets the air mass sensor, i had a customer come in with a airmass sensor that was buggered, so i swapped my sensor for theirs as it was the thursday afternoon before the easter weekend, i just used my landy and got a brand new sensor the following wednesday, customer was happy to have their car running for the long weekend

yeah, mine did it also after going through the crick at QMF, more good times

oh phew, thanks guys, ill reset it. i've gone through a worse puddle about a year ago where it starts smoking from the engine bay lol but no check engine light, haha.

anyway it seems to run fine so ill just reset it.

thanks guys!

You guys had some luck there, happened to s friend in a honda with cold air intake and bent the conrods requiring a rebuild

don't really know about it, the receptors are a bit sensitive about getting wet, it`ll obvious itself. try doing some key ons, that should totally reset it.. . .

It must of been a lot of water to actually cause damage to the engine.
At normal operating temps in recent manufactured cars, drops or trickle of water (should being the keyword) evaporate instantly due to the high heat.
Thats not to say that you can be reckless and barrel through a giant puddle.
If you go deep and fast enough you will probably simply push the water up the CAI causing the failure described above
But I cannot see this happening to the stock air intake systems (RA\NA) due to the design unless you plow into a lake....

I guess it depends on how the air intake system is design and how it feeds to the engine.
