Resetting the check engine light
#1
It came back on again, as well with my check fuel cap light.

first time it did it i changefd the cap and light went away, later on the light came back on, stayed on for 3 weeks then I got a CEL.

At that time, dan cleared it for me.

earlier this year when I had the battery done, the light and cel were back on but when the battery got changed the codes were forgotten/deleted/erased.

now, they're back again. fuel cap on the way to work, cel on the way back the next day ( so two trips in the mean time)

so... i just wanna reset it again, so when disconnecting the battery - is it the pos or the neg to clear the pcm memory?

I appreciate the offer guys, but I moved to Ottawa at the end of August last summer... might be a bit of a far reach for me to get any of you to read the code for me Tongue

Hi, I have a code reader, and it allows you to reset the CEL. I am located in Carp (just west of Ottawa). Let me know if I can help.

Oh yeah? Hmm... would there be any way of catching you when you're closer to the city?

now more than before, i need a code reader... lol

today the abs light and the traction control lights came on. shut the car down, wait 20 minutes, start up and its all off again. drive 200 feet... back on.

jacked the car up once i was at home and the rear wheel bearing is considerably worse than before and there is noise as the wheel turns.

could it be related?
also, what is the 'danger zone' for bad wheel bearings? like I said i've got more play in the wheel than before. i just need to get to work and back for a couple more weeks...

Could be related if your abs sensor or abs wheel is also buggered. But IIRC a code reader won't help you with ABS light.

The last time I had both ABS and TC lights on I had to pay the dealer 100 bucks to tell me what it was (I have a code reader - no codes from the OBDII) ... it ended up being real bad news ... it was the ABS computer on the master brake control valve, and they won't sell you a new computer - you have to buy the whole unit - IIRC correctly they quoted me 1400.00 to fix.

I'm not saying that this is what ails you ... but

but with the luck I've had with this car... who knows?

I have noticed for some time lately, especially on certain days that the front right brakes are more... 'grabby' and stronger and that at times the car would lean to the front right under braking due to it.

No clue if it's related, or if it's maybe something that got tweaked from hitting a snow bank earlier this winter?

I hope it's not too serious...
edit: I also said code reader as I checked in my with my step dad (Who had internet access) into what the causes were as I had pulled over. He said he was reading something about needing a code reader to find out what the problem really was - I just assumed he meant a cel code reader.

since we got on the topic of my ABS system... today I could hear what sounds like a mix between a tin rattle and sparks.
Also, today while sitting in my parking lot coming back from a drive there was a ticking coming from the engine. rev's go up, so did the speed of the tick. I pushed the clutch it and the ticking went away. Haven't been able to reproduce it since.

I've got a bad feeling about all this :\
