DESCRIPTION
The intake camshaft has 3 teeth on its outer circumference. When the camshaft rotates, changes occur in the
signals to determine the camshaft angle, and sends it to the ECM.
The crankshaft position sensor plate has 34 teeth. The pickup coil generates 34 signals for each crankshaft
the ECM detects the engine speed.
DTC

MONITOR DESCRIPTION
When the sensor output voltage remains at less than 0.3 V, or more than 4.7 V for more than 4 seconds, the
ECM stores a DTC.
