CRANKSHAFT POSITION SENSOR (Continued)
tonewheel rotates, the notches pass the tip of the
CKP.
When the leading edge of the tonewheel notch passes
the tip of the CKP, the following occurs: The interrup-
tion of magnetic field causes the voltage to switch high
resulting in a signal of approximately 5 volts.
When the trailing edge of the tonewheel notch
passes the tip of the CKP, the following occurs: The
change of the magnetic field causes the signal voltage
to switch low to 0 volts.
The Camshaft Position Sensor (CMP) also provides
a signal to the Engine Control Module (ECM) at all
times when the engine is running. The ECM uses
this CMP information primarily on engine start-up.
Once the engine is running, the ECM uses the CMP
as a backup sensor for engine speed.
