HI, just purchased a 2001 Accent GSI (1.6L/std trans/no air). After about a week of driving it, the MIL came on. I scanned it and it shows no codes. I d/c the battery cable to eliminate the light, but it came back on after a few days of driving, again no code comes up on my scanner, and the scan says MIL off.

Any clues out there?

cheers

 

possible short to ground in the intrument cluster. u a tech?

 

I had this problem. First, check to see if there is a hole or leak in the muffler. Next, check for a hole or leak in the flex pipe in the muffler assembly. This is a heavy braided metal pipe. The oxygen sensor is attached to it. It is the sensor which is causing the engine light to go on. A hole in the muffler can be repaired with muffler weld paste or tape. A hole in the flex pipe - it needs to be replaced. Just the flex pipe, not the whole muffler assembly.
Hope this helps.

 

thanks for the hint, but no holes are present

cheers
