TROUBLE DIAGNOSIS

Basic InspectionEBS011XF
Precaution:
Perform Basic Inspection without electrical or mechanical loads applied;

Headlamp switch is OFF.

On vehicles equipped with daytime light systems, set lighting switch to the 1st position to light
only small lamps.

Air conditioner switch is OFF.

Rear defogger switch is OFF.

Steering wheel is in the straight-ahead position, etc.

DTC P0340 CMP SENSORPFP:23731
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.
On Board Diagnosis LogicEBS0121N
NOTE:

If DTC P0340 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652
or P0653. Refer to EC-1579, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
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 DTC is detected, go to EC-1527, "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. 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.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.
4. If DTC is detected, go to EC-1527, "
Diagnostic Procedure" .

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.)
