DTC P0340 CMP SENSORPFP:23731
DescriptionEBS01KH1
The camshaft position (CMP) sensor senses the retraction with cam-
shaft (left side) to identify a particular cylinder. The camshaft position
(CMP) sensor senses the piston position.
When the crankshaft position (CKP) sensor system becomes inoper-
ative, the camshaft position (CMP) sensor provides various controls
of engine parts instead, utilizing timing of cylinder identification sig-
nals.
The sensor consists of a permanent magnet and Hall IC.
When engine is running, the high and low parts of the teeth cause
the gap with the sensor to change.
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 ValueEBS01KH2
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
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.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
