SOURCE: 2002 kia rio, where is the crankshaft position
A crankshaft position (CKP) sensor is mounted on
the front of transmission case adjacent to the flywheel. The CKP sensor
is a hall-effect type sensor that generates voltage using a sensor and a
target wheel mounted on the crankshaft. There are 58 slots and one
longer slot on the target wheel. When the slot in the wheel aligns with
the sensor, the sensor voltage output is low (approx. 0V). and it is
high (approx.5V) when a slot is not aligned with the sensor. During one
crankshaft rotation there are 58 rectangular signals and one longer
signal. The ECM calculates the frequency to compute engine rpm to
determine the injection duration and ignition timing. Using the signal
differences caused by the longer slot, ECM identifies which cylinder is
on top dead center
