I understand that the cam position sensor measures the revolutions of the gear on the end of the camshaft so it can tell the computer when to spray fuel. The part I don't understand is how the sensor works. I can understand that it measures the spinning of the shaft that it shares with the oil pump, but what I don't get is why it needs to be set at a 54* angle to the centerline of the engine. If the sensor is calibrated on the inside why does it need to point in a spacific direction? I've already marked on the outter casing where it needs to be put back, but the part I don't understand is how the cam sensor positioning tool is going to help me in getting the shaft turned to the right angle in relation to the sensor... Does anyone understand what I'm asking? Can you help me understand?
Thanks, you guys all rule
