Your car won’t fail right away if there’s a problem with your camshaft ignition sensor by any means. You can still drive without one, but the overall performance of your vehicle will degrade over time.

What happens when a cam sensor goes bad?

As the camshaft position sensor weakens, the signal it transmits to the vehicle’s ECM also weakens. Eventually, the signal will weaken so much the signal will switch off, and so will the engine. This can happen while the vehicle is parked, or while you are driving. The latter can be a dangerous situation.

Can a cam sensor stop a car from starting?
