check engine light....

i was driving home from work yesterday and my check engine light came on. i have no clue why?
i havent noticed any changes in terms of the way she runs (still running like a champ)
she burns oil in the mornings so i topped it up half a litre, light was still on

tomorow im guna flush my rad change my oil and change my tranny fluid, ill check the plugs too.

if anyone has any ideas itd be great im pretty stumped
thanx

what's your mileage? Mazda's have the light come on at certain intervals just so people will go into the dealership to get bent over, er, I mean for a service. There should be a plug under the dash on the drivers side that has an identical mate right beside it, just swap plugs and voila! no more check engine light. I'm pretty sure there was another thread about this a couple months back.

there is a 1 pin plug just above the kick panel where the harness' and relays are plugged in too, the colours of the plugs i think are black, brown and white, you can miss it, you'll probably see the one thats unplugged first, look up deep inside and you'll find it

i was thinkin that cause i just rolled over to 290,000

ill tryin find that plug

wow what would i do with out the Bscene... to think i was almost guna pay some fuktard to swap a plug around.

thanks alot guys

At 60K miles, 80K, 120K, etc., the Malfunction Indicator Light will come on, supposedly so you get dealer to check emissions but more likely so they can try to sell you a timing belt replacement. By the way, do get the timing belt replaced every 60K miles, and maybe get the water pump changed at the 120K point along with it, as it's an internal water pump, behind the timing belt, and mine started leaking at that point, so it's a big labor savings $$$ to do both at once. The Malfunction Indicator Light is re-set by swapping a wire push-on connector under the dash, driver side, right next to the firewall; it's hard to see, lie down and look up, there will be a bare connector, just swap it, then swap back next time the light goes on at that set interval.

what is the default wire setup which plugs are suppose to be plugged in permanetly.
