[y_why_wai]

ur check light is on when u start the car or when u driving the car suddent on??
if start on check light is sensor problem, after running suddent on is ECU problem,
in ur case 70% is ECU, u can go Auto used sparepart place to borrow 1 ECU to test it.

[KAY 3333]

siok siok the light on for every time i driving when i restart some time it still there but some time it gone off

 

[J101]

probably a loose connection.

 

[KAY 3333]

thn how to fix it

 

[suduRed]

thn how to fix it

try check all sensor connection and reinput it...

 

[KAY 3333]

okok i try it

 

[y_why_wai]

3 possible thing, 1st is O2 sensor, 2nd MAP sensor, 3rd is ECU.tis three thing cannot check 1, better change the 2nd hand and test it, but one thing.... wat engine u use for now?

 

[J101]

the problem started when you change to the bigger exhaust. probably due to weight, loosen 02 sensor and vibration, the CEL 1 came off. maybe u can hoist the car and try fixing it properly.

it sudden on. after i change bigger exzhaust thn this problem always show
but i tried off my engine and start again but the light still show. after two to three hours off the engine then the check light gone

 

[sasuke]

Agreed with u 2... check the O2 sensor since it is the last thing u touched on ur car.
