What are the symptoms of camshaft bearing damage?
2 Answers
Damage to the camshaft sensor will manifest in the following ways: 1. Difficulty in ignition, making it hard to start the engine. 2. When the car is hot, it's difficult to accelerate or the engine may stall directly. 3. Increased fuel consumption, lack of power, and inability to accelerate. 4. The car may continuously shake while driving. Below is relevant information about the camshaft sensor: 1. The camshaft position sensor is used to collect the camshaft's movement angle signal and input it into the Electronic Control Unit (ECU) to determine the ignition timing and fuel injection timing. 2. To distinguish it from the Crankshaft Position Sensor (CPS), the camshaft position sensor is generally denoted as CIS. 3. The function of the camshaft position sensor is to collect the position signal of the valve camshaft and input it into the ECU, enabling the ECU to identify the top dead center of cylinder 1's compression, thereby facilitating sequential fuel injection control, ignition timing control, and knock control. 4. The camshaft position signal is also used to identify the first ignition timing during engine start-up.
Last time I encountered a damaged camshaft bearing while driving, it was truly unpleasant. After starting the car, the engine emitted a continuous knocking sound, as loud as metal sheets colliding, especially more pronounced during acceleration. The power dropped significantly; even when pressing the accelerator, the car barely moved, feeling much more sluggish than usual. The steering wheel also vibrated, making my hands numb while driving. The oil pressure light flickered from time to time, alerting me to a system issue. Delaying repairs could lead to more severe failures, such as the camshaft seizing or complete engine failure. I immediately headed to the repair shop, where the mechanic diagnosed severe bearing wear. Replacing it cost me quite a bit. So, I advise regular drivers: if you hear any unusual noises or feel a lack of power, don't hesitate. Early inspection can save you worry, money, and ensure safety.
