DTC P0340 CAMSHAFT POSITION SENSOR
DTC P0340 CAMSHAFT POSITION SENSOR
PFP:23731
DescriptionEBS008YN
The camshaft position sensor identifies a particular cylinder by
means of signals from the sensing plate (with five protrusions)
installed to the camshaft. The datum signal output is detected 90°
signal and sent to the ECM. The sensor signal is used for fuel injec-
tion control and fuel injection timing control.
ECM Terminals and Reference ValueEBS008YP
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.)
On Board Diagnosis LogicEBS008YQ
DTC Confirmation ProcedureEBS008YR
Before performing the following procedure, confirm that battery voltage is more than 10V.
