CHECK CRANKSHAFT POSITION SENSOR.
1) Turn the ignition switch to OFF.
2) Remove the crankshaft position sensor.
3) Measure the resistance between terminals
of crankshaft position sensor.

Terminals

No. 1 — No. 2:

Is the resistance between 1 and
4 kΩ?

Go to step

Replace the crank-
shaft position sen-
sor. <Ref. to
FU(STI)-35,
Crankshaft Posi-
tion Sensor.> <Ref.
to FU(w/o STI)-35,
Crankshaft Posi-
tion Sensor.>

CHECK HARNESS BETWEEN ECM AND
CRANKSHAFT POSITION SENSOR CON-
NECTOR.
1) Disconnect the connector from ECM.
2) Measure the resistance of harness between
ECM connector and crankshaft position sensor
connector.

Connector & terminal

(B137) No. 17 — (E10) No. 1:
(B137) No. 25 — (E10) No. 2:

Is the resistance less than 1 Ω? Repair the poor

contact of ECM
and crankshaft
position sensor
connector.

Repair the harness
and connector.
NOTE:

In this case, repair
the following item:
• Open circuit in
harness between
ECM

connector

and crankshaft po-
sition sensor con-
nector
• Poor contact of
coupling connector

BM:DTC P0336 CRANKSHAFT POSITION SENSOR “A” CIRCUIT RANGE/PER-

FORMANCE

DTC DETECTING CONDITION:

• Detected when two consecutive driving cycles with fault occur.

• GENERAL DESCRIPTION <Ref. to GD(H4DOTC)-130, DTC P0336 CRANKSHAFT POSITION SENSOR

“A” CIRCUIT RANGE/PERFORMANCE, Diagnostic Trouble Code (DTC) Detecting Criteria.>

TROUBLE SYMPTOM:

• Engine stalls.

• Failure of engine to start
CAUTION:

After servicing or replacing faulty parts, perform Clear Memory Mode <Ref. to EN(H4DOTC)(diag)-63,

OPERATION, Clear Memory Mode.>, and Inspection Mode <Ref. to EN(H4DOTC)(diag)-49, PROCE-

DURE, Inspection Mode.>.

Step

Check

Yes

CHECK CONDITION OF CRANKSHAFT PO-
SITION SENSOR.
Turn the ignition switch to OFF.

Is the crankshaft position sen-
sor installation bolt tightened
securely?

Go to step

Tighten the crank-
shaft position sen-
sor installation bolt
securely. <Ref. to
FU(STI)-35,
Crankshaft Posi-
tion Sensor.> <Ref.
to FU(w/o STI)-35,
Crankshaft Posi-
tion Sensor.>

CHECK CRANK SPROCKET.
Remove the timing belt cover.

Are crank sprocket teeth
cracked or damaged?

Replace the crank
sprocket. <Ref. to
ME(STI)-60, Crank
Sprocket.> <Ref. to
ME(w/o STI)-58,
Crank Sprocket.>

Go to step

CHECK INSTALLATION CONDITION OF
TIMING BELT.
Turn the crankshaft, and align alignment mark
on crank sprocket with alignment mark on cylin-
der block.
