I think I found the culprit. Logic tells me it's the LED brakelights I installed before this Check Engine thing happened. Check engine is gone after replacing it with a pair of P30 standard brakelights (sana wag na magpakita ever). I don't have the technical explanation, but I could only speculate (maybe sort of imbalance in the electrical system and the dashboard display). So I suggest you guys remove all new electrical devices you installed and observe if it will go away. Good luck..
