No "plenum grommet mod". Not sure if you think that causes or cures the issue.
No rain either...dry as a bone here.
The only clue I have (since the car is running and braking fine (though not sure if ABS is working - need to get it out in a parking lot to see) is that when I deleted the P0102 error code the CEL light went out for several minutes while the ESP light stayed lit.
Thanks for asking and any ideas. I ordered a brake sensor switch (only $ 10 + shipping) and will post back next week when that arrives.
