Check Engine Light

It sounds like something in the traction control system is malfunctioning. There should be a way to shut it off manually. Check your owners manual for how to do that and see if the light persists. Probably should get it checked out anyway.

Bulb may be blown or has been removed.

I'M HAVING A STARTING PROBLEM. I HAVE GAS, AT LEAST A HALF TANK. BUT THE GAUGE

READS ZERO. TRUCK TRYS TO START WITH STARING FLUID BUT FUEL DOES NOT SEEM TO BE GETTING TO INJECTORS. i WAS WONDERING IF IT WAS THE FUEL PUMP OR THE FUEL SENDING UNIT?

It is a vapor leak in the fuel system. Starting in 1996 vehicles check for leaks down to .020 inch.

Check engine light can literally point to hundreds of things. The only right way to find out is to take it to someone with electronic diagnostics.

Disconnect your battery, and leave it disconnected for at least 24 hours. The battery backup on the computer will die after 24 hours, at that point, the service engine indicator is reset.

If your car has less that 150,000 miles on it, you are still covered under warrantee and can take it up with Honda at their cost. This is because of a settlement between Honda and the feds for a faulty ECU in 1997's. Honda's deal was to extend the emissions components warrantee out to 150,000 miles.

It does not matter who makes the plugs, if the light is still on after reseting the computer it usually means something else is wrong. sometimes an actual computer scanner is required to reset. check autozone, they do it for free.

You need a code reader to plug in to diagnostic port and erase it. 97 is around the cut off though, not sure if you need OBDI or II. Most shops can do this for you, just make sure the reason it was on is fixed, otherwise it comes back on in 25 miles after a reset.

The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

MAKE CERTAIN that that is all that it is and not signalling the failure of some vehicle system! If it is TRULY the 'check engine' light it is probably signalling that you've gone past the recommended mileage for an oil change.

check engine light. it means you should eather check your "codes" or go to an auto shop and tell them your check engine light is on. sometimes its free.

First P0301 relates to a problem with Cylinder 1 (301, 301=cyl2 303=cyl3 304=cyl4)P0301 can be caused by many of the items identified in the books and on the web. Items such as spart plugs, spark plug wire, Coil tower and/or related ECM. cylinder compression, IntakTPS, MAF, fuel enjector and related intakcomponents, and EGR and items related toexhaust. It is a good idea, regardless of what I'm about to tell you below, to check and make sure everything I mentioned above is in good working order. After spending hours (about 7)assuring the above and ending up very frustratedbecause P0301 reappeared after a few short rides,later that night I got back on the web/internet to search for something new. I came across an append that talked about P0301 and this poor fellow also had4 or 5 other codes. I almost skipped overreading this one because Iassumed there were to many problems and I did not want to chase any more false leads. Being desperate, I read on.In the middle of his append he talked about using a spray product like PB Blaster and spraying it on the intake manifold gasket. If there was a leak the idle/RPMs would change. Becausemy car was running fine (except for the P0301 code) I assumed it couldn't be this, and I read on. Ithen though, wait a minute. This is avery simple test to perform (less than 5 minutes) what the hell, let's do it. Guess what... The idleincreasedabout 300 RPMs then. I repeted the test (sprayed several times) and the idle increased each time I sprayed around Cyl 1 area of the intake gasket. This was the first positive indication of a real problem I found. It took about45 minutestoseperate (not remove) the intake manifold from the cylinder head and sure enough the gasket had a major brake (about 1/8") atCYL 1 intake. I went to my local Advanced Auto, ordereda new gasket and the nextmorning installed it (being very sure to first snug downthe intake nuts and thentorque them downto 14 "inch" pounds in rotation starting from the center and working my way towords both ends. When this was done. P0301 went away andnow (about a month later) the car is running excellent. I drive itevery day and have taken it on one trip of 250 miles out and back (500 miles). So be sureEVERYTING mentioned is in goodorder but BE VERY SURE you don't overlook vacume leaks at the INTAKE MANAFOLD GASKET. It's a simple 5 minute test.

Oh my Gosh how vague can you be? Gas cap evap hose O2 sensor fuel problem

Ideally you would want to know why the check engine light is on. It could be something serious or it may not be. Are there any other symtoms/noises? It could be one of many things. The engine needs to be scanned for the error codes and a diagnosis can be made from there. Autozone or Advance auto will pull the codes for free. Hope this helps. "G"

Hey Xiaolin=It is probalby in deed of a good tune up and just missing. Take it to a good garage. GoodluckJoe

Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related.

It is 8-10 degree before top dead center with engine warmed to operating temp., RPM's at the proper range and the check engine connector jumped at TE1 and E1.

Many places do not want to put an OBD reader on if the check engine soon light is not on. However, the codes ARE stored in memory. Get yourself a Haynes Repair Manual for your vehicle (or check at your local library to see if there is one available), go to Chapter 6 and read how you can retrieve the codes yourself - also listed are all the codes and what each one means. Good luck.

In 1996, computers changed to save codes. ( OBD II) .

Many parts houses can read the codes.

It is possible.

Replace the four capacitors in the computer or replace the computer itself

The check engine light will come on in a 2004 Kia Sedona 431 if a misfire is detected, the timing is wrong, or a weak spark is detected. There are many other possible causes which can be narrowed down by connecting an OBDII code reader to the vehicle.

This is for a part lock/unlock throttle control circuit. The brain of the trans. I'd reset the battery, disconnect for 5 mins, then rescan after driving so the car gets hot and cold and relearns as to reset the IM monitors. If problems are still present, then it will show up again.
