I disconnected the negative on the battery to reset the ecu because my check engine light was on and I know that its a bad o2 sensor thats why it comes on, but I don't have the cash to fix it right now. So after disconnecting the batt and I turned my car back on the light was off, but it came back on about 5-10seconds later.
Is there a way to reset the ecu so that the light doesn't come back on for this problem?
If I go to the garage and get them to hook it up to there comp, the check engine light won't come on for a while (3-4months), is there a way I can do that without having to pay the $30 to get it hooked up to the comp?
I had a problem like that and it was my 02 sensors, just order them online from www.hondaautomotiveparts.com they are like 37 bucks each, my car run much better and got better gas mileage once I replaced them, I heard you should replace them about every 50,000 miles.
check to see if your gas cap is turned at least 3 clicks. Also check to see if your engine oil is low, I had that problem and was short about .7litres of oil and had to pay an hours labour for them to find the problem. Try to fix it yourself first and if all else fails, go to honda.
you know that you have a bad o2 sensor...problem is right there...... you have a bad o2 sensor...so the car is telling to get it fixed!!
you are supposed to reset the ecu after you do some addon or mod... reseting ecu means what it is..allowing the ecu to restart to check to se if everything is ruuning right, it's comming on because something is not right
