P0445 Mazda -

Question

I understand the Evap system in a 2001 Mazda MPV comprises just 4 components (Advance Solenoid, Purge Solenoid, Fuel Tank Pressure / Vacuum sensor and Charcoal Canister). My CEL shows a code of P0455 and I have already changed the fuel tank cap, two O2 sensors and the MAF sensor to no avail, except it has coat me a bomb already. The car is old and I do not wish to throw more money at solving this problem, so I shall be grteful if someone can confirm my assumption about the EVAP system components above and please let me know know how much approximately each component costs, so I can figure out my next steps!
Thanks.

Answer 1

the issue is that this car does not use code p0445 in the service manual its a valid code but not for this make and model and year.

I would use a different OBD-II reader and see if it gives you a different code.
