DescriptionEBS0121L
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 ValueEBS0121M
Specification data are reference values and are measured between each terminal and 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.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

DTC Confirmation ProcedureEBS0121O
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-1366, "
