Diagnostic Procedure with Diagnostic Trouble Code (DTC)
ENGINE (DIAGNOSTICS)
Step Check Yes No
1CHECK ANY OTHER DTC ON DISPLAY.Is any other DTC displayed? Check the appro-
priate DTC using
the “List of Diag-
nostic Trouble
Code (DTC)”.
EN(H6DO)(diag)-
69, List of Diag-
nostic Trouble
Code (DTC).>
Go to step 2.
2CHECK POWER SUPPLY OF CAMSHAFT
POSITION SENSOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from camshaft
position sensor.
3) Measure the voltage between camshaft
position sensor connector and engine ground.
Connector & terminal
(E74) No. 1 (+) — Engine ground (–):
Is the voltage more than 10 V? Repair the battery
short circuit
between main
relay connector
and camshaft
position sensor
connector.
Go to step 3.
3CHECK POWER SUPPLY OF CAMSHAFT
POSITION SENSOR.
1) Turn the ignition switch to ON.
2) Measure the voltage between camshaft
position sensor connector and engine ground.
Connector & terminal
(E74) No. 1 (+) — Engine ground (–):
Is the voltage more than 10 V? Go to step 4.Repair the open or
ground short cir-
cuit between main
relay connector
and camshaft
position sensor
connector.
4CHECK HARNESS BETWEEN CAMSHAFT
POSITION SENSOR CONNECTOR AND
ECM.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ECM.
3) Measure the resistance between camshaft
position sensor connector and ECM.
Connector & terminal
(E74) No. 2 — (B134) No. 21:
(E74) No. 3 — (B134) No. 22:
Is the resistance less than 1
Ω?
Go to step 5.Repair the open
circuit between
camshaft position
sensor and ECM.
5CHECK HARNESS BETWEEN CAMSHAFT
POSITION SENSOR CONNECTOR AND
ECM.
Measure the resistance between camshaft
position sensor connector and engine ground.
Connector & terminal
(E74) No. 2 — Engine ground:
Is the resistance more than 1
MΩ?
Go to step 6.Repair the ground
short circuit
between camshaft
position sensor
and ECM.
6CHECK CONDITION OF CAMSHAFT POSI-
TION SENSOR.
Is the camshaft position sensor
installation bolt tightened
securely?
Go to step 7.Tighten the cam-
shaft position sen-
sor installation bolt
securely.
7CHECK CAMSHAFT POSITION SENSOR.
Check waveform of camshaft position sensor.
Module (ECM) I/O Signal.>
Is there any abnormality in
waveform?
Replace the cam-
shaft position sen-
sor. FU(H6DO)-19,
Camshaft Position
Sensor.>
Go to step 8.
8CHECK POOR CONTACT.
Check poor contact of ECM connector.
Is there poor contact in ECM
connector?
Repair poor con-
tact in ECM con-
nector.
Replace the ECM.
