DTC P0341 CMP SENSOR
PFP:23731
Description
EBS013OG
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
EBS013OH
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.)

DTC Confirmation Procedure
EBS013OJ
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1.
Turn ignition switch ON.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Start engine and let it idle for at least 5 seconds.
If engine could not start, keep ignition switch at START position
for 5 seconds.
4.
If 1st trip DTC is detected, go to
EC-202, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.
