tion.
Is CMP sensor installed properly and connector con-
nected securely?Go to Step 3. Correct.
3 Check Wire Harness and Connection.
1) Disconnect connector from CMP sensor.
2) Check for proper connection to CMP sensor at
each terminal.
3) If OK, turn ignition switch ON and check for volt-
age at each terminal of sensor connector discon-
nected. See Fig. 1.
Terminal “B+” : 10 – 14 V
Terminal “Vout” : 4 – 5 V

Is check result satisfactory?Go to Step 5. Go to Step 4.
4 Was terminal “Vout” voltage out of specification in
Step 3 check?“W” wire open, short or
poor connection.
If wire and connection
are OK, substitute a
known-good ECM and
recheck.“Bl/B” or “B/R” wire
open, short or poor
connection.
5 Check Ground Circuit for Open.
1) Turn ignition switch OFF.
2) Check for continuity between “GND” terminal of
CMP sensor connector and engine ground.
Is continuity indicated?Go to Step 6.“B/R” wire open or
poor ground connec-
tion.
6 Check CMP Sensor for Operation.
1) Remove CMP sensor from sensor case.
2) Remove metal particles on end face of CMP sen-
sor, if any.
3) Connect each connector to ECM and CMP sensor.
4) Turn ignition switch ON.
5) Check for voltage at terminal E19-11 of connector
connected to ECM by passing magnetic sub-
stance (iron) (1) while keeping approximately 1
mm (0.03 in.) gap with respect to end face of CMP
sensor. See Fig. 2 and 3.
Does voltage vary from low (0 – 1 V) to high (4 – 5 V)
or from high to low?Go to Step 7. Replace CMP sen-
sor.
7 Check signal rotor for the following.
See Fig. 4.
Damage
No foreign material attached
Is it in good condition?Intermittent trouble or
faulty ECM.
Check for intermittent
referring to “Intermittent
and Poor Connection” in
Section 0A.Clean rotor teeth or
replace CMP sensor.
