A cam positioning sensor is a tool that determines the place of a camshaft in an inside combustion engine. This info is utilized by the engine’s digital management unit (ECU) to regulate the timing of the engine’s valves. A defective cam positioning sensor could 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 needs to be related to the sensor’s sign wire, and the engine needs to be working. 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 needs to be set to the ohms setting, and the probes needs to be related to the sensor’s terminals. The multimeter ought to show a resistance worth that’s throughout the producer’s specs.
