But after a couple of usage it turns on back again on the day I need to use it on a long drive, then after the drive turns on again. but when i finally came back home it turned off again and until now after many times of usage the check engine light is off. Now the unit is on hibernation again for 1 week, need to check again this coming weekend.

Been in hibernation for months.

But for the this update it is confirm that the O2 sensor is the culprit. I gamble purchase an oxygen sensor on ebay for 4700
and hail mary it worked the CEL now is off but at first connection it was off and thinking its a defective item. But I rememeber to reset the ECU by disconnecting the battery for 15 mins. Then I when I crank the engine tadaaa the CEL is off.
