Question about 2003 Mitsubishi Galant

1 Answer

Check engine light is on.

Car runs and drives just fine. Gas cap is on tight. This has happened in the past, and was repaired at the dealer, I believe they replaced a sensor.
The vehicle is now past the warranty period, and this wpuld be a billable situation at the dealer. Any ideas as to what I should do.

    Thanks , ......... I will try that right away. !!!

    Well what do you know .....?????

    Your suggestion to disconnect the battery for a while seems to have worked. I had already disconnected the negative battery cable before I had posted the question, then I went back out into the garage and reconnected the battery, started the engine, and the check engine light DID NOT come back on.

    Like you say, I wonder what caused it to come on in the first place. I had been driving in quite heavy rain with puddles on the road ...... I wonder if that is what caused it. If I recall correctly, I believe the first and last time that this happened the car was also being driven in heavy rain, etc. But like I said in my earlier comment, the car was still on warranty, and i had taken it to the dealer. Maybe the check engine light will come back ..... I hope not.

Hi,
There are two kinds of codes that makes the light come on hard code and soft code. with a hard code you need a scan tool to remove it but with a soft code all you have to do is disconnect the battery for about a minute, I always go for two. Now if the code is remove then the light goes out and if hard the light stays on. But one thing you have to ask is why did the light come on in the first place. Try the disconnecting the battery if the code goes out just keep track to see how long it takes for the light to come back on.

Cheers.

Car is running fine, just had a few days of cold weather and now my check engine light is on troubleshooting code p1132 and p1152 are showing. Meaning?


Don't know the codes, but check to make sure your gas cap is on tight. Sometimes in our rush to get back inside the warm car we don't make sure the cap is tight and it can cause the CEL to come on. Sounds simple but happens all the time.

What does it mean when engine light is on


Hi George:
If the "Check Engine" light came on soon after a fill-up at a gas station, check if your gas cap is closed properly. If the gas cap wasn't on tight, this could be the problem. Secure the gas cap properly and if there is no other problems, the "Check Engine" light should clear itself out in a few days of driving. If the gas cap was tight, there is some other problem. Have your car computer scanned to see what is wrong. It could be some minor problem, but it also could be something more serious that can cause more damage to your vehicle if not repaired in time. Some garages or parts stores often offer to scan your computer for free. Others will charge you a diagnostic fee. If your car is fairly new, I'd advise to visit your dealer for this, because it's possible that the problem is still covered by the original warranty and can be repaired for free or a minimum charge. Check your owner's manual for more details.



Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Wife driving her 2003 Tiburon and the engine light came on. Car checked the oil okay drove home with light on? Seems to be okay? Should we take to a dealer to have it checked?


Yes, oil level has nothing to do with the Check Engine light. Make sure the gas cap is on tight. If it was loose, just keep driving it will go off on its own in a few days. If its tight, there is another problem and a dealer or good repair shop can check it out for you. keep away from any chain store operation.

Check engine light is on, but the car seems to be


The purpose of the check engine light is to inform the driver that the car's ECM has registered a problem. It then stores a code in it's memory that can then be "pulled" by a hand held diagnostic trouble code reader and usually the issue an be corrected. More times than not, the car will seem to be running fine even with the light on because the ECM will compensate for the problem as much as it can to keep the system functioning. One thing you can do is remove the gas cap and put it back on making sure that you securely tighten it until you hear 3 clicks. After driving the car for 30-50 miles, the light may go out. If it does then the gas cap was not tightened completely causing air to enter the system (the system utilizes vacuum so it must be sealed air tight). If the light stays on, take it to a Dealer or trusted mechanic for further inspection. ALWAYS BE SURE YOUR GAS CAP IS TIGHTLY SECURED AFTER EVERY FILL UP OR THE LIGHT WILL COME ON AGAIN>

Have a dealer or garage check your Oxygen (O2) sensor. As a quick fix, try disconnecting and reconnecting your car battery. Sometimes this will reset the check engine light.Good Luck!

2005 chevy cobalt check engine light


make sure the gas cap is on tight. vapor recovery system depends on the closure of the gas cap. if that did not solve your problem, I would suggest to get a new gas cap first, before going to the dealer or any repair shop for a turn-up.
