Hi,

The CEL on my 2005 Mercury Grand Marquis (94k miles) just went on and 3 codes popped up :

- P0457
- P0457 (same code twice)
- P172C

P0457 refers to an EVAP leak, but I can't find much information about P172C. Some sites say it's a transmission code, other a solenoid... I'm really confused.

Do you guys have any idea ?
