PLZ help: engine check light QUESTION

[evoX2]

i have changed my exhaust system i.e. the o2 & exhaust sensors have been reallocate in the new piping but after that i drive for long time or rev 5k & above the engine check light will on, so what the problem?

Btw, i am using VAFC so it has by pass the ECU right? Will the engine check light error harm my engine?

thank you.

happened to me once when the mechanic didn't fix my exhaust holder properly and end up damaged my o2 sensor due to vibration......find replacement at chop shop but also faulty pc. after about 5k rpm check engine light on....finally jump it with a resistor and now perfect.............not sure if it will efect the fuel consumption because resistor value is fix.....

since there is o2 and exhaust, i presume that u are driving an early model b16a(OBD0)? take a look at your ecu there should be a clear window with red light to check on your error light. the list is available on the net.

by putting VAFC, it doesnt eliminate the check error light.

it will harm your engine if the check light indicates something else other than the minor problems.
