STEP 20. Check the crankshaft sensing blade.
Q: Is the crankshaft sensing blade in a good condition?

YES : Replace the crankshaft position sensor. Then go to

Step 21.

NO : Replace the crankshaft sensing blade. Then go to

Step 21.

STEP 21. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to

Diagnostic Function

− OBD-II Drive Cycle − Procedure 6 −

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0335 set?

YES : Retry the troubleshooting.
NO : The inspection is complete.

.

CIRCUIT OPERATION

• The camshaft position sensor power is supplied

from the MFI relay (terminal No. 4).

• Terminal No. 1 of the camshaft position sensor is

grounded with ECM (terminal No. 40) <M/T> or
PCM (terminal No. 16) <A/T>.

• A 5-volt voltage is applied on the camshaft posi-

tion sensor output terminal (terminal No. 2) from
the ECM (terminal No. 88) <M/T> or PCM (termi-
nal No. 56) <A/T>. The camshaft position sensor
generates a pulse signal when the output termi-
nal is opened and grounded.

.

TECHNICAL DESCRIPTION

• The camshaft position sensor functions to detect

the top dead center position of the number 1 cyl-
inder and to convert that data to pulse signals
that are input to the ECM <M/T> or PCM <A/T>.

• When the engine is running, the camshaft posi-

tion sensor outputs a pulse signal.

• The ECM <M/T> or PCM <A/T> checks whether

pulse signal is input while the engine is cranking.

.

DESCRIPTIONS OF MONITOR METHODS

• Camshaft position sensor signal does not

change.

• Camshaft position sensor signal is not normal

pattern.

.
