What are the symptoms of a faulty crankshaft position sensor in a Haval H6?

Symptoms of a faulty crankshaft position sensor in a Haval H6 are as follows: The car may experience a lack of power and inability to accelerate when going uphill; there may be no idle speed, or the engine may shake severely at idle, with the exhaust pipe making popping sounds when accelerating, occasionally accompanied by the engine stalling after the popping sounds; the car may fail to start, and when attempting to start the vehicle, a knocking sound may be heard inside the engine, which is the sound of the piston hitting the valve. Here is some relevant information about the sensor: Definition: A sensor is an electronic device capable of measuring acceleration forces. Acceleration force is the force acting on an object during acceleration, similar to the Earth's gravitational force, or gravity. The acceleration force can be a constant. There are two types of accelerometers: one is the angular accelerometer, which is an improvement on the gyroscope. Principle: The sensor is a testing instrument used to convert the physical signal of acceleration into an electrical signal that is easy to measure. The differential capacitive force-balanced acceleration sensor converts the measured acceleration into a change in the capacitance of a capacitor.
As a Haval H6 owner, that crankshaft position sensor failure was really a headache. The car wouldn't start easily - it took several attempts before the engine would fire up, coughing like it had a cold. While driving on flat roads, there would be sudden jerks with poor acceleration and difficulty maintaining speed. At idle, the car shook violently as if it was about to stall. The check engine light stayed constantly illuminated on the dashboard, making me worry about breaking down midway. After inspection at the 4S shop, the technician explained the faulty sensor was causing inaccurate fuel delivery and ignition timing. Spending over 500 yuan to replace it made driving much smoother. Always pay attention to your vehicle's condition - avoid driving in rainy weather or uphill as these conditions can easily trigger problems. Early repairs mean early peace of mind.
I have some knowledge about cars. The crankshaft position sensor acts like the monitoring eye of the engine, tracking the rotation of the crankshaft. When it fails, the ECU can't receive signals and loses precise control over fuel injection and ignition. The result is that your Haval H6 may experience hard starting, engine shaking, sluggish acceleration, or even unexpected stalling. The check engine light will definitely come on, and sometimes fuel consumption increases due to improper air-fuel mixture. The cause of the failure could be oil contamination, oxidation, or wiring aging, and a simple OBD scan can diagnose it. Timely replacement can prevent bigger issues, but be careful not to misdiagnose it as a spark plug problem.
Safety comes first, a faulty crankshaft sensor is dangerous while driving. Symptoms include failure to start or stalling on the road, which can cause accidents especially at high speeds or in traffic. If the engine shakes violently, accelerates sluggishly, or the warning light stays on, you should pull over and inspect. I recommend pulling over and calling a tow truck, don't risk driving to avoid damaging other components. For prevention, regular maintenance and cleaning the circuit are advised. Repair costs are not high but save you trouble.
