ENGINE AND EMISSION CONTROL SYSTEM
CODE NO.15 (P0340) CMP SENSOR CIRCUIT
(SENSOR SIGNAL NOT INPUTTED FOR 2 SECONDS AT ENGINE CRANKING)
1. ECM
2. CMP sensor
3. Rotor
4. CMP sensor coupler
NOTE:
If starter circuit is open (i.e., start signal circuit is OK but starter fails to run), this DTC is stored in memory
at starter switch ON, even through CMP sensor is in good condition.
When starter motor fails to run and this DTC appears, check starter circuit first.
STEP
ACTION
YES
NO
1
1) Disconnect couplers from ECM.
2) Measure resistance between “E33-203”
and “E33-211” terminals of ECM coupler.
CMP sensor resistance: 185 – 275
W
at –10 – 50
C (14 – 122
F)
3) Measure resistance between “E33-203” ter-
minal of ECM coupler and ground.
Insulation resistance: 1 M
W
or more
Were measured resistance values in above 2)
and 3) as specified?
Go to Step 2.
“Bl” wire open or short.
“B/W” wire open or
short.
Poor terminal connec-
tion of CMP sensor cou-
pler.
If wire and connection are
OK, replace CMP sensor.
2
1) Check CMP sensor referring to Section 6F.
Is it in good condition?
Poor “E33-203” or
“E33-211” terminal con-
nection of ECM coupler.
If connection is OK,
substitute a known-good
ECM and recheck.
Faulty CMP sensor.

NOTE:
Upon completion of inspection and repair work, perform DTC Confirmation Procedure, referring to page
6E1-30 to confirm that the trouble has been corrected.
