A cam positioning sensor is a tool that determines the place of a camshaft in an inner combustion engine. This info is utilized by the engine’s digital management unit (ECU) to manage the timing of the engine’s valves. A defective cam positioning sensor may cause quite a lot of engine issues, together with tough idling, poor gasoline economic system, and lowered energy.
There are a number of methods to check a cam positioning sensor. One technique is to make use of an oscilloscope to measure the sensor’s output sign. The oscilloscope must be linked to the sensor’s sign wire, and the engine must be operating. The oscilloscope ought to show a waveform that corresponds to the place of the camshaft. One other technique of testing a cam positioning sensor is to make use of a multimeter to measure the sensor’s resistance. The multimeter must be set to the ohms setting, and the probes must be linked to the sensor’s terminals. The multimeter ought to show a resistance worth that’s inside the producer’s specs.
