Go to “ENGINE
DIAG. FLOW
TABLE”.
2
Is engine cranked?
Go to Step 3.
Go to “CRANKING
SYSTEM” section.
3
Engine Start Signal check:
(1) Check engine start signal circuit referring to
“DTC P1500” in this section.
Is the result satisfactory?
Go to Step 4.
Repair or replace.
4
CMP Sensor Power Supply Voltage check:
(1) With ignition switch OFF, disconnect CMP sensor
coupler (1).
(2) With ignition switch ON, check voltage between
C09-2 and C09-1 terminal.
Is the voltage 10 – 14 V?
Go to Step 5.
Faulty “Bl / B” wire
and / or “Gr / Y” wire.
5
CMP Sensor (REF) Signal check:
(1) With ignition switch OFF, connect CMP sensor
coupler (1).
(2) Disconnect couplers from ignition coil assembly
and fuel injectors.
(3) With ignition switch ON and crankshaft turned
slowly, check voltage between C51-3-10 and
C51-3-21.
Does voltmeter indicator deflect between 0 – 1 V and
4 – 6 V 6 times while crankshaft turned two revolutions?
Go to Step 6.
Faulty “Y / Bl” wire
or CMP sensor.
If OK, substitute a
known-good ECM
(PCM) and recheck.
6
CMP Sensor (POS) Signal check:
(1) With ignition switch ON and crankshaft turned
slowly, check voltage between C51-3-9 and
C51-3-21.
Does voltmeter indicator deflect between 0 – 1 V and
4 – 6 V?
Poor C51-3-9 and / or
C51-3-10 terminal of
ECM (PCM) coupler
connection.
If OK, substitute a
known-good ECM
(PCM) and recheck.
Faulty “Y / G” wire or
CMP sensor.
If OK, substitute a
known-good ECM
(PCM) and recheck.
