DTC P0340 CMP SENSOR
PFP:23731
Description
EBS013O8
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
EBS013O9
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
EBS013OB
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-196, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

1.
CHECK STARTING SYSTEM
Turn ignition switch to START position.
Yes or No
Yes
>> GO TO 2.
No
>> Check starting system. (Refer to
.)
2.
CHECK GROUND CONNECTIONS
1.
Turn ignition switch OFF.
2.
Loosen and retighten engine ground screws. Refer to
.
OK or NG
OK
>> GO TO 3.
NG
>> Repair or replace ground connections.
3.
CHECK CMP SENSOR POWER SUPPLY CIRCUIT
1.
Disconnect camshaft position (CMP) sensor harness connector.
2.
Turn ignition switch ON.
3.
Check voltage between CMP sensor terminal 3 and ground with
CONSULT-II or tester.
OK or NG
OK
>> GO TO 4.
NG
>> Repair open circuit or short to ground or short to power
in harness or connectors.
Does the engine turn over?
Does the starter motor operate?
