LEVE, thanks for the link to the service manual.
Nick, turning the key on and off three times shows the codes in the mileage indicator.
Well the codes are actually P0442 and P0455. So it is or was showing a both the P0442 - Evap Leak Monitor 0.040" leak detected and P0455 - Evap Leak Monitor large leak detected.
The service manual does not specifically note what priority level these codes are (page 25-7). It notes that after 3 "good trips" the light is extinguished and after 40 warm-up cycles the counter is reset. But for these trips there are several criteria, one of which is time. Since my daily commute is less that 10 minutes, I may not be getting credit for a possible loose gas cap fix.
Since this is my daily driver, I called the dealer and will be bringing it in later today. They commented on performing a smoke test. Therefore my question is, shouldn't they just reset the OBD system and see if the codes are still there or do they have to look for a problem first?
