what will occur if I do not replace the "charcoal canister" in the fuel evaporative system other than the
malfunction indicator light staying ON ?
fuel evaporative system
Re: fuel evaporative system
first of all, why do you think you need to replace the charcoal canister? You may have codes that say it's not working correctly but that may be from other things besides the canister. Vent valve, purge valve, evap leak, fuel tank pressure sensor, etc.
If you do actually need the canister replaced and you don't replace it, what would happen? Well, some cars will run differently with the check engine light on. Some turn off the cruise control. Some turn off the AC. If the fuel tank vent valve is stuck it could affect when you fill up gas. (keep clicking the pump off) If the purge valve is stuck open you could flood the engine when you fill gas. (won't start without wide open throttle to clear flood) Most vehicles will let you run normally if it's just an evap code that isn't a vacuum leak that affects idle. How is it running now? It shouldn't change much but you won't know if something else goes wrong because the check engine light is already on. Unless the light starts flashing.
