Your Mazda 5 relies on the crankshaft position sensor to monitor the speed and position of the crankshaft, and also the engine's valves in relation to the pistons, as well as the engine's overall function. It's a very important sensor that passes on critical information. Signs of a malfunctioning crankshaft position sensor include: check engine light, ignition malfunction, stalling and backfiring, engine vibrations and disruptions in engine function.
