i am from Sialkot.
i have Vitz 2010 and my car is showing yellow light(check engine sign) after constantly crossing the rain water, in past two months it disappeared for sometime but not for long time, i made a visit to a mechanic for computer inspection but he couldn't solve the issue and now fuel consumption is too high, like 75-100 km reduction per tank full 
..
i don't know what to do.
can any one guide me please !!!
Regards,
