: SES light

08-25-03, 07:09 AM
I just purchased a 98 concours no SES light but history codes were present, went through the OBD and retreived
PO463 History:fuel level sensor;
PO502 History: Low Speed Sensor;
PO603 History Long Term Mem reset;
PO404 History EGR valve open operation.
Since they we are all history I cleared them. Now the SES light is on and I get PO404 History along with the SES light being illumiated. Why is the light all of a sudden coming on and will it eventually go off, or will I now have to fix the egr problem to get it off???? Thanks in advance.

You must troubleshoot the EGR issue first. Probably a clogged passage.
