Can a missing fuse make engine light come on?
Yes, a missing fuse can cause the engine light to come on. This is because the fuse is responsible for providing power to the engine control unit (ECU), which is the computer that controls the engine. If the fuse is missing, the ECU will not be able to receive power and will not be able to control the engine. This will cause the engine to run erratically and the engine light to come on.
