After repairing the cause of the code, you can clear it with a scan tool.
Add oil!
The check engine light on a 2003 Honda Accord will be triggered when something on the engine is malfunctioning. To rid the check engine a light the ECU will need to be reset.
drill a very small hole on bottom of the light
Unplug the battery for like 45 secs.
Take it to a shop and get the engine serviced. Kinda makes sense if you think about it.
The check engine light is causes by an emission system failure. If the cause of the code has been repaired, the code can be cleared with a scan tool.
Try disconnecting the battery for about 10 mins. or have vehicle scanned to determine the problem, engine light also comes on when gas is pumped while car is on sometimes
a nuisance to get rid of
You can disconnect your batteries for about 30 minutes, and it'll reset the ECM and the check engine light will be gone... momentarily, until the next diagnostic runs and the same fault is detected. You want to get rid of the check engine light, you find out the reason why and have it fixed.
Go to the fuse that is on the battery terminal, and remove it for about 20 seconds, then put it back in. This will reset the ECU which will rid you of the check engine light. If the problem that caused the light to come on is still present the code will be set in the ECU and the check engine light will be turned on again until the problem is corrected.
You can't
flick your key on and off 3 times really fast the gauge cluster will read codes starting with a p write down the codes and look them up also you can temporarily get rid of the check engine light by disconnecting the negative battery cable and turning your key a couples times with the battery still disconnected this will get rid of the light for about a day or so but the problem causing the check engine light will need to be fixed to get it to go away permanantly....
