DTC P0340 CMP SENSOR (PHASE)PFP:23731
Component DescriptionEBS00BHQ
The camshaft position sensor (PHASE) senses the retraction with
intake valve camshaft to identify a particular cylinder. The crankshaft
position sensor (POS) senses the piston position.
When the crankshaft position sensor (POS) system becomes inoper-
ative, the camshaft position sensor (PHASE) provides various con-
trols of engine parts instead, utilizing timing of cylinder identification
signals.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
thegapwiththesensortochange.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor changes.
ECM Terminals and Reference ValueEBS00BHR
Specification data are reference values and are measured between each terminal and body ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
