When to reset the Check Engine light after replacing an EVAP canister?
When a pressure issue is detected or excess vacuum is discovered in the fuel cell, the ECM detects the issue and triggers the Check Engine Light to come on. This light needs to be reset after replacing the EVAP emissions control canister if that is the source of the error code.
How do you replace an EVAP canister in a car?
To avoid stripping bolts, spray penetrating fluid onto the bolts and the clips that hold the EVAP canister onto the vehicle. Since this part has been exposed to road grime, water and, in some cases, salt; it’s probable that the bolts have rusted.
When to replace an evaporative emission control canister?
When the EVAP emissions canister fails it triggers an OBD-II error code (0499) collected by the vehicle’s ECM and tells a mechanic that there is a pressure problem with the EVAP system. If the EVAP canister is damaged or not working properly, it needs to be replaced, as it can’t be serviced or repaired on the vehicle.
