Answers: No.
Go to autozone, have them read out the trouble codes for you. Fix the problem. The code usually points you within the right direction, most often a has-been sensor.
Disconnecting the battery and reconnecting it will not clear the memory. Fixing the problem will unanimously turn off the lighting, although it may take various driving cycles before the stored background is overwritten.
The check engine light will come on to caution you of problems when any of the systems the computer monitors return a value outside the parameter it expects to see.
Now, if the O^2 sensor happens to move about out, what additive do you deliberate would help it? Or if a spark plug begin to misfire due to either a bleak high tautness wire, or a malfunctioning injector, again, what additive would sustain that?
To make it simple, no.
Bring it to a shop and enjoy the code scanned(Auto Zone will scan it for free) Replace the defective component.
No cleaners will clear the code. The code has to cleared next to the scan tool.
You can disconnect your battery and turn switch on for 20 sec.
That will clear the code.
No, the check engine light works stale your ecu and monitors your emissions system. If the flimsy comes on that indicates there is a potential problem near your emissions system.
