I don't think the charcoal canister would cause the engine check light to come on because the EVAP system is pretty simple on these cars. The ECU controls the EVAP solonoid to allow an intake vacuum to draw vapours from the charcoal canister under certain conditions. The ECU knows whether it's open or closed & and that's it. There's no pressure sensor in the tank or anywhere else to give any indication that the system is leak free or that the canister is blocked.
EDIT: If the EVAP solonoid is stuck open there would be a constant vacuum sucking vapours in to the inlet manifold. That could cause a rick condition that the ECU couldn't make adjustments for. If removed from the car the operation of the solonoid is easy to check. Checking the ECU has control over it as it should is more of a challenge.
