To answer your question; yes, it can. I had a couple o2 sensors go bad at the end of the exhaust manifold that would spring up limp home mode and a "drivetrain malfunction" every time I would give it the beans. Anything that alters the vehicles ability to calculate fuel to air ratio on the fly is going to cause a malfunction due to the fact it starts guesstimating when a sensor goes bad and the system cannot guess the mix faster than you can step on the gas. Would recommend pulling codes to make sure.
