CheckEngine on, why?

[RevMesh]

it all started one night at traffic light. that time just drag the car up to 0.5 bar and the check engine light lit on. thought it would just be minor thing and would reset by itself on my next engine startup, i ignored to check in my engine bay. but eversince, it always 'on' after bout 5 minutes i start up my car, if not, it'll 'on' after i drive it like bout 50 metres. anybody encounterred this problem before??

things i did already; chnged the MAF sensor, change the cam sensor(like distributor one), totally plug out sAFC Neo, replace the ecu. move move shake shake some sockets like cam sensor, oil pressure switch, water temp socket.


any solution or troubleshooting ideas would be much appeciated, thanks

bro.... you still haven't mention what car you driving with what engine. ..... from what ECU to what ECU and what MAF to what MAF....

Since inssuficient of the information , very difficult to let ppl find out your problem .

a faulty knock sensor was the culprit... hope will be helpful for other members, so check all ur sensors whenever ur car gives CEL while the car running good or just slighty slack
