DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)
ENGINE (DIAGNOSTICS)
Yes
Repair harness
and connector.
NOTE:
In this case, repair
the following:
* Open circuit in
harness between
camshaft position
sensor and ECM
connector
*
Poor contact in
ECM connector
Poor contact in
coupling connector
Repair ground
Step
CHECK HARNESS BETWEEN CAMSHAFT
POSITION SENSOR AND ECM CONNEC-
TOR.
1)Turn the ignition switch to OFF.
2)Disconnect the connector from camshaft
position sensor.
3)Measure the resistance of harness between
camshaft position sensor connector and
engine ground.
Connector & terminal

Engine ground:
No
Go to step 2.
Go to step 3 .

Engine ground:
1 CHECK CONDITION OF CAMSHAFT POSI-
TION SENSOR.
5 CHECK CAMSHAFT POSITION SENSOR.
1)Remove the camshaft position sensor.
2)Measure the resistance between connector
terminals of camshaft position sensor.
Terminals
NO. 1

NO. 2:
Check
;
the resistance more than
00 kR?
s the resistance less than 10
L?
s the resistance less than 5
2?
s
the camshaft position sensor
nstallation bolt tightened
jecurely?
s the resistance between 1
md 4 kR?
Go to step 4.
Go to step 5.
Repair poor con-
tact in camshaft
position sensor
connector.
Repair harness
and connector.
NOTE:
In this case, repai
the following:
Open circuit in
harness between
camshaft position
sensor and ECM
connector
Poor contact in
ECM connector
Poor contact in
coupling connect0
Tighten camshaft
position sensor
installation bolt
securely.
Replace the cam-
shaft position sen.
