An easy fix, if the check engine light is on find an Auto Advance, they can clear the code for you. Any auto parts store may be able to as well, Auto Zone is another one that may be able to help.

Could actually be the gas cap loose or bad, but the best thing to do is go down to your local auto zone and get them to put the scanner on it and see what's showing up.

Can a lose gas cap cause the engine light to come on on a 2009 280 volvo


Answer to this is YES. Replace cap with about 3 clicks this is enough. If your check engine light is on the cars computer wil erase after a few miles. GOOD LUCK FRIEND.

Check engine light and AT light came on


First, double check that the gas cap is good and tight. Sounds silly, but sometimes a loose gas cap will cause the check engine light to come on. Failing that, take the car to someone who can read the codes. You might have a bad or lazy O2 sensor but the codes are the quickest way to tell.

Error codes P0128 & P0442


Well code 128 is for the engine running too cool. Which is usually a thermostat problem. But it could be the coolant temp sensor.
You may have a different sensor for the gauge and for the computer.
Code 442 is for a small leak detected in the EVAP system. It can be a faulty gas cap, but since you have replace the cap, its probably a hose or gasket. The computer vents the gas tank to the vapor canister when the engine is running. It checks gas tank pressure to make sure all valves are closed when you turn the truck off.

Major auto parts stores have code readers and will read out your codes for free. The engine light indicates that at least one code is waiting to be read.

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>

2002 kia rio rxv check engine light came on again..


the check engine light is not caused by any wrong fluid level or dirty air filter or anything else like that, it is caused by well over 100 faults that can occur in the computer controlled electronic engine and emission controls, u will need to go to a Kragen or Autozone parts store and get a free OBD 2 fault code test to get the code that set your light.

Check engine light light on


U need to check to see why the light is on, it indicates a problem, even if the car still runs fine. You can have the codes read that are stored in the cars computer by most parts stores (they offer it as a free service). They will tell you the codes, ask what they mean and what u should do to correct the problem. Check it out soon, as u can end up with more problems to fix if u let this go w/out correcting it.
