Check Engine Lights Up

[CoDer]

Hi sirs,

Naglilight-up po yung check engine ng kotse ko. I first noticed this, four months ago, after I had an engine wash. I've made a research and I read na it happens pag daw may nabasang wiring or something. Solution was to remove the battery then ikabit ulit. It worked! Ngayon, naglilight-up na naman sya. I wonder if may alam po kayong pwede kong pagpatingnan? Somewhere in Makati, Bicutan, or nearby areas po sana...

TIA

Pa scan mo na lang muna para ma pin point ang problem and never have your engine washed in the future.
