What's this ECS light do?


Recommended Posts

Maybe check your o2 sensor...My turbo wagon's ECS light was coming on randomly for about a month or so, no symptons, no crappy starts or running...Just randomly the light would come on, then I replaced the o2 sensor and it hasn't come back on.

Mine does the same thing, yet throws me either a Crank Angle, or an EGR... whatever it feels like doing that day.

 

If the car runs good, gives you good MPG, and doesnt throw a horrible code... electrical tape is your best friend :) or you can go the other route if you like your dash to look clean, and pop out the bulb...
