After bringing my car in for the 75k service a few days ago, the CEL came on last night.
Here's what was done:
Recall - Headlight switch connector
New brake pads/shoes in front & rear, rotors turned
Oil changed, new filter
Radiator, coolant flushed
Doors, hinges lubricated (yeah, this is suspect #1 :p )
Cabin air filter replaced
Looking at the OBD-2 codes list, I'm guessing it was the radiator flush or brake work that caused this? I'm off to check the gas cap and disconnect the battery to see if it goes away. ttyl
