HELP! 02 rsx base k20A3
The car keeps throwing the same evap code (p1457) I’ve replaced the canister itself, the shut off vent valve on the canister, I replaced the evap by pass solenoid that’s on the other side of the canister, I replaced the purge valve on the throttle body, IACV, gas cap, and im still getting this evap leak code.
…also got the ECM checked

and everything is good there

 

See the following TSBs:

2002 Acura RSX base A/T:
Can anyone help me get to the end of this code. I’ve replaced a lot of parts of the EVAP system and I’m still getting this code.
parts I’ve replaced:
-gas cap
-purge valve
-charcoal canister
-shut off vent valve
-two way by pass ( on the other side of the canister)
- fuel tank vapor vent
-fuel tank pressure sensor
-hose from the canister to the tank

is there anything else that can trigger this code?

 

Did you rule out TSB 08-010? If not, may need to replace the fuel vent tube..if you haven't already.

 

After replacing all EVAP components , from gas cap to fuel tank vapor vent, I keep getting this p1457 code & was wondering if I could have zapped my PCM. The code will come back on after a good 200-300 miles and kinda seems during foggy weather
