Eccentric shaft sensor plays a vital role in automobile engine. By measuring the Angle of the eccentric shaft, it provides the actual parameters for the electronic valve control system, thereby adjusting the camshaft to ensure that the best intake valve lift can be achieved in various operating conditions. This regulation function is essential to the performance and efficiency of the engine
When the eccentric shaft sensor fails, it will affect the normal operation of the engine. For example, if any of the signals from the eccentric shaft sensor are missing, the engine may go into emergency mode to try to maximize the valve opening to control the intake volume. In addition, if the mounting bolt of the center magnetic wheel is magnetized or a normal bolt is used instead of a non-magnetic bolt, the sensor may fail completely, resulting in the engine not starting
When diagnosing the fault of the eccentric shaft sensor, you can check whether the wiring harness between the DME and the sensor is damaged or short-circuited, and whether the plug connector is dirty or loose. At the same time, check whether the mounting bolt of the central magnetic wheel is magnetized, replace the new eccentric shaft sensor if necessary, and check whether the fault code has changed. If the fault code does not change, there may be other causes
