What Causes Excessive Signal from the Magotan Camshaft Position Sensor?
2 Answers
The excessive signal from the Magotan camshaft position sensor is caused by incorrect timing. The camshaft is subjected to periodic impact loads. The contact stress between the cam and the tappet is very high, and the relative sliding speed is also considerable, resulting in significant wear on the cam working surface. More relevant information is as follows: Note 1: The camshaft position sensor (phase) detects the position of the camshaft protrusion to identify the working cylinder. The camshaft position sensor senses the position of the piston. When the crankshaft position sensor (position) system fails, the camshaft position sensor (phase) will use the timing of the cylinder identification signal to provide different control to various engine components. Note 2: When the protrusions on the camshaft pass the solenoid valve of the CMP sensor under the rotation of the camshaft, it causes a change in magnetic flux. The CMP sensor uses a processing circuit to convert the change in magnetic flux into a digital waveform (rectangular wave). The ECU detects the engine speed and camshaft position based on the camshaft position waveform.
I've driven my Magotan for so many years and encountered issues with the camshaft position sensor signal being too high. Usually, it's because the sensor itself is faulty, such as aging or internal component damage, leading to incorrect signal output. Wiring connections are also common culprits, like short circuits or loose connectors, causing the signal to spike when the voltage is too high. Another possibility is an ECU (engine control unit) malfunction, where the computer misreads the data and triggers an alert. An excessively high signal can cause unstable idling, poor acceleration, or even sudden engine stalling, which could lead to accidents on the road. When the check engine light comes on or error codes like P0340 appear, I usually check the sensor connector first to ensure it's clean and free of corrosion, then use a diagnostic tool to measure the voltage. Regular maintenance is key—keep the engine bay clean to prevent dust and dirt buildup. If problems arise, it's best to replace the sensor at an authorized repair shop for a reliable fix.
