What are the symptoms of a faulty intake camshaft sensor in a Honda CR-V?

The symptoms of a faulty intake camshaft sensor in a Honda CR-V are: 1. Difficulty in ignition and engine starting; 2. Difficulty in accelerating when the engine is warm or the engine may stall directly; 3. Increased fuel consumption, lack of power, inability to accelerate, and continuous shaking of the vehicle while driving. The function of the camshaft position sensor is to collect the position signal of the valve camshaft and input it into the ECU, allowing the ECU to identify the top dead center of cylinder compression for sequential fuel injection control, ignition timing control, and knock control. The camshaft sensor position signal is also used to identify the first ignition timing when the engine starts, and it can identify which cylinder piston is about to reach the top dead center, hence it is also known as the cylinder identification sensor.
If the intake camshaft sensor is faulty, I can feel it very obviously when driving my Honda CRV. It takes a long time to start the engine when turning the key, and the car shakes like dancing when idling. There's no power when accelerating, the speed increases slowly, and the fuel consumption spikes. The engine light on the dashboard stays on, which is annoying. I'm also worried about sudden stalling while driving, especially in traffic jams. This sensor controls the engine's ignition timing, and when it's broken, the air and fuel mixture becomes uneven, making the engine run poorly. This issue is common in Honda CRVs. I suggest going to a repair shop to replace the part as soon as possible—it usually costs a few hundred bucks. Delaying the repair might damage other components like the exhaust system, leading to higher repair costs and more trouble. Don’t take it lightly—safety first.
