You can disconnect the battery for about 10 seconds, but the check engine
light will come back on. It sounds like you should just run it and hope it
lasts 3 weeks. It is probably cheaper to rent one for 3 weeks than to fix
So, you mean it will be off and will come back on? In every case? I mean,
maybe there was something wrong and now it is OK - even in that case it will
come back on? If I disconnect the battery, should I know any code to run it
back? I have never done it before so I'd like to know if I can do it without
If the Check Engine Light comes on, There IS a problem. Period. And problems
fix themselves. The only way to "turn off" the light is to fix the problem. Go
local auto parts store like Auto Zone and have them pull the fault codes, then
the codes here. They will be in a form like P0455, P0175, etc.
Hey, my engine light came on and I was told to disconnect the battery and
wait five minutes, while waiting pump the brakes three to five times. then
reconnect the battery. that resets the computer. iF something is wrong it
will come back on than you need to get it checked. I have an 02 ford escape
and it works!
If the idiot light is the only indicator of a problem, it should be fine for
a few weeks of light driving. Still, get it checked by a mechanic with a
computer code reader. That won't cost much, and you'll (and the next driver)
at least have peace of mind. I know that with some late '80s Fords, the
"check engine" light would come on periodically as a reminder for
maintenance. It would stay on for some time unless there was a manual reset.
You could check the owner's manual to see if that's the case with your car.
