the check engine light could stay on because of other sensors. for example,the Power Steering sensor could be bad...this will cause the engine light to come on and other sensors could cause the engine light to come on. just get rid of the van. most sensors when they go bad cost anywhere from $200-$600 just because of the location of the sensor. manufacture put sensors in hard to reach places to keep you from replacing them,so that you will bring it in to dealer and pay over inflated repair cost.
