Failure sensors and check Engine does not turn on

The ECU reviews every certain period of time the sensors does not keep them controlled if the ECU notice a high difference for a prolonged period gives notice to the check, from there it follows that to check a check failure the ECU is reset and then the vehicle is handled until again, this check turns on again is to prevent erroneous or old diagnosis that is not erased

I apologize I have a Verna 2005, but I do not turn on what I did was ringed, but when I started if I start, but only one day and then I no longer want, I already check my head and it is not, but it is a sensor because the acceleration camera is filled with gasoline, but does not want to teach. Thanks if they could support me

I hope to help what I understood when certain sensors disconnect the check light does not turn on, I had passed me with a Hyundai locio TPS sensor with a cut cable and yet it did not turn on the check as the vehicle had been bought just opting pro revive ECU but it was fine in the end that in the instrument panel the light bulb of the check had bridged it with the oil signal From the ignition and went out when the vehicle turned on, I hope you serve any questions comment.

Tell me the check Engine, turn on when you put the key on position on without even starting it?

Your mechanic I revoked if the engine is well placed on time?
