What are the effects of a faulty camshaft position sensor?

The effects of a faulty camshaft position sensor: Although the car can be started with high-voltage ignition, the starting time will be prolonged, and issues such as unstable idling, severe shaking, inability to accelerate, slow engine speed, high fuel consumption, and excessive exhaust emissions may occur one after another. If the camshaft position sensor is faulty, it is advisable not to drive the car. Forcing the car to start may be possible, but it will cause significant wear and tear on the vehicle. During the starting process, phenomena such as crankshaft reversal may occur, and the intake manifold may experience backfire, making the car accelerate weakly as if it has a cylinder misfire. If the engine speed can exceed 2500 RPM, the situation may improve slightly, but problems like black smoke and high fuel consumption will still persist.
I've been driving for years, and I once had a camshaft position sensor fail—what a nightmare. Starting the car was a real struggle, taking multiple attempts to fire up. Sitting in the driver's seat, I could feel the engine shaking with unstable idle, like it was having a heart attack. Acceleration felt sluggish, and fuel consumption skyrocketed. A full tank that used to last a week now disappeared in just a few days. The scariest part was when the car nearly stalled on the road once, forcing me to pull over immediately. Never ignore this issue—a faulty sensor confuses the car's computer, messing up fuel injection and ignition timing. Over time, it can damage internal engine components, leading to much costlier repairs. My advice: use an OBD scanner to check trouble codes ASAP and get a new sensor installed at a repair shop. It usually costs just a few hundred bucks and ensures safe driving.
