Step
1 5) If OK, then check the continuity between each terminal
and ground.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
CKP sensor continuity
(Infinity) (Bl – Ground, G – Ground)
Are the resistance and continuity OK?
2 1) Crank the engine several seconds with the starter motor,
and measure the CKP sensor peak voltage at the
coupler.

2) Repeat the 1) test procedures several times and
measure the highest peak voltage.
Is the voltage OK?

Engine General Information and Diagnosis:
Yes
Go to Step 2.
• Bl or G/Bl wire of the
harness side open or
shorted to the
ground.
• Loose or poor
contacts on the CKP
sensor coupler or
ECM coupler
(Terminal "14" or
"31").
• If the wires and
connection are OK,
intermittent trouble or
faulty ECM.
• Recheck each
terminal and wire
harness for open
circuit and poor
connection.
• Replace the ECM
with a known good
one, and inspect it
again. Refer to "ECM
Removal and
Installation in Section
1C (Page 1C-2)".
1A-33
No
Replace the CKP
sensor with a new one.
• Inspect that metal
particles or foreign
material stuck on the
CKP sensor and rotor
tip.
• If there are no metal
particles and foreign
material, then replace
the CKP sensor with
a new one. Refer to
"CMP Sensor
Removal and
Installation in Section
1C (Page 1C-2)".
