Distributorless ignition systems require a crankshaft position sensor (CKP), and sometimes also a camshaft position sensor (CMP). These sensors serve essentially the same purpose as the ignition pickup and trigger wheel in an electronic distributor, the only difference being that the basic timing signal is read off the crankshaft or harmonic balancer instead of the distributor shaft.
Crankshaft position sensor set ignition timing, supply the RPM signal, and determine engine speed. When the crankshaft position sensor fails, it stops transmitting the signal. The crankshaft position sensors signal contains the vital data for the […]
There are a number of symptoms that can point to your Crankshaft Position Sensor failing but can also be confused with the same symptoms caused by issues with your ignition or fuel injection systems. If you […]
Crankshaft-Camshaft Position Sensors produce a signal that tells the Fuel Injection Computer or the Ignition Control Module the exact position of the pistons as they come up or go down in the compression cycle. What […]
