Open Question

1998 BMW 323 I P-Code 446

My check engine light is on and the code is 446.
And from what I found is its a ''evaporative emission control system vent control circuit malfunction''
I need to know how important is this for a car, can i get that replaced little later or that has to be replaced immediately.
Any rough idea how much will that cost me ?

Hello I have 1997 toyota Camry with code 450 and pending code 446 I took the gas cap off this morning with the car running and screwed it back on tight and that's where I got the pending code I hear it...


These codes usually trigger the check engine light to ON if the car is fueled or fuel tank cap is removed with the engine in start position.
To delete the codes, remove the key from ignition, remove the battery negative terminal for 5 Seconds or more. Reconnect the battery terminal, start the engine, let it idle for 10 minutes.
Error Code: P 0446
Description:
Evaporative Emission (EVAP) System, Vent Control - Circuit Malfunction
Possible Cause:
Wiring.
Evaporative emission (EVAP) canister purge valve.
Engine control module (ECM).

Error Code: P 0450
Description:
Evaporative Emission (EVAP) Pressure Sensor - Circuit Malfunction
Possible Cause:
Wiring.
Evaporative emission (EVAP) pressure sensor.
Engine control module (ECM).

Hope that will work. If the problem persists contact a service technician.

Check Engine light on 1998 BMW Z3 roadster


yes the light is because of the gas cap being gone (sets code in evaporative emissions system), replace the gas cap, disconnect the battery for five minutes and that will turn of/reset the light, make sure u have the radio code before u do this, if u don't u will have no radio after the battery is disconnected..
