Diagnostic Trouble Code (DTC) P0402 indicates that Self-Test has detected
EGR flow at idle.
PA 3L SVT
Is this possible it detected it once and set the light or it happened "X' times then sets the light? Is this one of thoseCEL's that after "X" driving cycles it will reset?
Thanks

I only have P 0402.
Interesting article of course our cars don't use an EVR but what ever these EGR systems with OBD II look to be more problematic
than the earlier ones. If someone could just come up with a way to keep the carbon build up at bay?
