- The repair shop did a "smoke test" and it was determined that I needed to replace my Charcoal Cannister, in which I did.... I also replaced the oxygen sensor (the one near the catalytic converter) (I also replaced the GAS CAP too....with a FACTORY toyota gas cap from the dealer) In fact all of my parts I purchased from my local TOYOTA dealership.
3 days later, my check engine light came back on and had it scanned again and the same code re-appeared (P0440) and it also said: EVAP CONTROLLER.
My question is: I am not familiar with an EVAP controller, (do I have 1 or 2 EVAP controllers) and where are they located (Its not part of the Charcoal Cannister that I just bought is it?
How expensive are they? How much would the labor costs be?
