Car Forum / Honda Cars / April 2007Turning off the damn "check engine" light?
Every time I start my Civic on a steep downhill slope at high altitude, the "check engine" light come on. It costs $80 bucks to find out nothing is wrong and get the light turned off. Is there any cheaper way to get it turned off? I need that indicator in case something were to *actually* go wrong with the engine.

Bush, 9/7/2006 Spend about $100 one time and get a OBDII reader. Check Ebay or your local auto parts store. Even the basic ones have a "reset" button that will erase the codes and turn off the light. Are you sure there isn't something wrong when the light comes on? --Jeff > Every time I start my Civic on a steep downhill slope at high altitude, > the "check engine" light come on.

Your computer is trying to tell you SOMETHING. In my country there's several places that will read codes for free, just to get you in the door. Without the CODE, wait 6 days and repost on Psychic Wednesday and we'll see if the good guessers can take a shot at your 'cure'.

I don't have a code, but I was verbally told "oxygen sensor". I'll bet the oxygen sensor is calibrated for sea level.

You posted here looking for advice, we cannot give any without knowing what the dealership saw. Cough it up now, young fella, or go dry for advice. By the way, you may want to give your year and model. This is quite relevant, believe it or not.

But Honda was using a 4-wire heated sensor in Accords and Preludes as early as 1990.

If it's throwing a code, you probably have a problem that should be addressed. It is not "nothing". The Oxygen sensor will not likely affect your driving experience, and won't likely hurt your car, but it will hurt your efficiency, and will keep your car from being inspected. And it is cheap to fix, relatively. Give the code here, and I am sure you will get a pretty definitive answer. One thing you can be pretty sure of, the Oxygen sensor is NOT calibrated for anything. Hondas work perfectly well in the mountains, just as they do at sea-level. Many of the Oxygen sensor problems involve difference in O2 levels between the 2 sensors. This can indicate a failing sensor, or perhaps a failing cat. Disconnect your battery for a few minutes. This will reset the ECU and clear any CELs unless the problem that caused the CEL hasn't gone away.

But simply doing that would be extremely foolish. > Is there any cheaper way to > get it turned off? See above. > I need that indicator in case something were to > *actually* go wrong with the engine. Generally speaking, something *has* gone wrong -- with the emissions controls. The alphanumeric code behind the MIL illumination is significant and should not be ignored, but investigated. What codes did your $80 reveal?

Is there any cheaper way to > get it turned off? Take a small piece of tape and cover over the warning light. That way nothing can ever go wrong. p.s. you're welcome |
