DTC P0341 CMP SENSOR
PFP:23731
Description
EBS014X8
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.
ECM Terminals and Reference Value
EBS014X9
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.)
