tion sensor and
ECM connector.
NOTE:
The harness be-
tween both con-
nectors are
shielded. Repair
the ground short
circuit of harness
with shield.
4
CHECK CONDITION OF CRANKSHAFT PO-
SITION SENSOR.
Is the crankshaft position sen-
sor installation bolt tightened
securely?
Tighten the crank-
shaft position sen-
sor installation bolt
securely.
5
CHECK CRANKSHAFT POSITION SENSOR.
1) Remove the crankshaft position sensor.
2) Measure the resistance between connector
terminals of crankshaft position sensor.
Terminals
No. 1 — No. 2:
Is the resistance 1 — 4 k
Ω?
Repair the poor
contact in crank-
shaft position sen-
sor connector.
Replace the crank-
shaft position sen-
sor. <Ref. to
FU(H4DOTC)-23,
Crankshaft Posi-
tion Sensor.>
