This would be just a guess on my part, but check engine light is what the computer has to indicate something wrong. Not just the engine. So a missing sensor is something wrong. The senor would need to be the same type as the one in the mirror you removed. I do not know where in the mirror it is located, just that it is in there. People on the board have had theirs replaced to try to correct bad readings. So that tells me it is an order-able part.
