    My emission control light came on about 2 weeks ago. I also tried the gas cap and it remains on. Other than spend a bundle of $ to scan it, I don't have any other ideas.

    I have a similar problem; with a twist. The ECS light comes on periodically when I start the car in the morning if the tempereature has been below freezing. It always resets itself later in the day. If the temperature at night is above freezing, the light never comes on. My mechanic checkked the fault signals for me at inspection (since my idiot boss still has my OBD II reader!) and saw no major fault codes.

1993 Honda accord, filled my tank and 2 days later the emission light is on.


Check your gas cap. if it is loose, tighten it until it clicks. It is vented, and if the vent is plugged then the computer will throw a code. Check you local auto parts store for a replacement cap - if it is cheap enough, replace the cap. It will usually take a day or two to have that light go off.

Why did the check engine light come on


The check engine light usually comes on due to emissions issues. I'd bet that tank of gas was the culprit. Run it nearly empty and then fill up again. If it doesn't go out in a few days take it to an auto parts store and have them read the code. At that point my guess would be O2 sensors.

My check emissions light has come on (2001 accord, ex) checked gas cap - on tight-


The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light is turned on the computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible faults that can occur in the system that turn the Check Engine light on, a leaking gas cap is just one of them. To know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

I have honda odyssey and the service engin coms on and the cod is p1456 so ineed to figur out thanks.


This probably means:
  • P1456: Evaporative Emission Control System Leak Detected (Fuel Tank System)
  • Usually this is because your gas cap was not fully tightened. Be sure to turn it until you hear a click.
  • After you tighten the cap, it might take a couple days of driving before the light goes-out.
  • Be careful to tighten your gas cap regularly, because otherwise it puts a heavy strain on your emission system.

I have a 2006 honda accord sedan.There is a orenge color engine shape sign on the left side (right under the head light sign) in the gauge. I need to know what does it mean?


Think this is your malfunction indicator light -indicates a problem with the emission control system. Generally caused by lose or missing gas cap. Make sure when putting gas cap back on that you turn it (tighten) so that it clicks three (3) times.

Emissions control light on 2004 Honda CRV is staying on, even after checking gas cap. What should I do? Is there a finite answer to indicate what the problem is, or will it be 'trial and error'? Also, how...


No big problem,turn the gas cap to tighten it,and keep turning it until it clicks,drive awhile,and it should reset itself.If it does not,replace the fuel cap.

A facut light is on an the car revs to two while in park


I don't exactly know which light you are referring to. If it is your check engine light (it is the second from the left in a block of four possible lights in the upper left of your instrument cluster, and it has a little engine outline in it), that means that your computer is saying that there is something wrong with your emission control system. The most common cause for that light, by the way, is a loose gas cap (not tightened down at least three clicks) or overfilling the gas tank (going past the nozzle click on the pump), but it could be other things which have to be checked at Honda service, or a service station that can scan your OBDII connector for the codes which will indicate the problem more concisely.
I would check my gas cap first. Also understand that just tightening the cap will not make the light go out immediately; it takes at lease three driving trips before it goes out. If it doesn't go out after three trips, better get it in to check for codes.
Hope this helps you understand what is going on.

1998 Honda Accord with a engine code(check eng.light) #1259. what do I need to do to fix it. thank you.


The manual for your Accord indicates the following:
This indicator comes on for a few seconds when you turn the ignition switch ON (II). If it comes on at any other time, it indicates one of the engine's emissions control systems may have a problem. Even though you may feel no difference in your vehicle's performance, it can reduce your fuel economy and cause your vehicle to put out excessive emissions. Continued operation may cause serious damage.
If you have recently refueled your vehicle, the cause of this indicator coming on could be a loose or missing fuel fill cap. Check the cap and tighten it until it clicks. Replace the fuel fill cap if it is missing. Tightening the cap will not make the indicator turn off immediately; it takes three driving trips.
If the indicator remains on past three driving trips, or the fuel cap was not loose or missing, have the vehicle checked by the dealer as soon as possible. Drive moderately until the dealer has inspected the problem. Avoid full-throttle acceleration and driving at high speed.
Hope this helps you find the problem.
