CRANKSHAFT POSITION SENSOR
(CPS)
Operation Overview
The crankshaft position sensor is essential to engine operation,
constantly monitoring the rotational speed (RPM) and position
of the crankshaft.
A ferromagnetic 60-tooth ring gear with two consecutive teeth
missing is mounted on the flywheel. The inductive speed sensor
is mounted 1.0 ± 0.26 mm (0.059 ± 0.010 in.) away from the ring
gear. During rotation, an AC pulse is created within the sensor
for each passing tooth. The ECU calculates engine speed from
the time interval between the consecutive pulses.
The two-tooth gap creates an “interrupt” input signal,
corresponding to specific crankshaft position for PTO cylinder.
This signal serves as a reference for the control of ignition
timing by the ECU. Synchronization of the CPS and crankshaft
position takes place during the first two revolutions each time
the engine is started. This sensor must be properly connected at
all times. If the sensor fails or becomes disconnected for any
reason, the engine will quit running.
CPS Test
The CPS is a sealed, non-serviceable assembly. If fault code
diagnosis indicates a problem within this sensor, test as follows:
1. Disconnect CPS (3-wire) harness connector on the left-
hand side of the vehicle located below the transmission.
2. Connect an ohmmeter between the pin terminals leading
from the Yellow and White wires. A resistance value of
560Ω ± 10% at room temperature (20
° C / 68° F) should
be obtained.
