DTC P0341 CAMSHAFT POSITION SENSOR “A” CIRCUIT RANGE/PERFORMANCE (BANK 1 OR SINGLE SENSOR)

DTC DETECTING CONDITION:


• Immediately at fault recognition

• GENERAL DESCRIPTION


TROUBLE SYMPTOM:


• Engine stalls.

• Failure of engine to start


Important

After repair or replacement of faulty parts, conduct Clear Memory Mode and Inspection Mode .


WIRING DIAGRAM:


CHECK ANY OTHER DTC ON DISPLAY.

Is any other DTC displayed?

Yes

Inspect DTC using “List of Diagnostic Trouble Code (DTC)”.


No


CHECK HARNESS BETWEEN CAMSHAFT POSITION SENSOR AND ECM CONNECTOR.

Turn the ignition switch to OFF.

Disconnect the connector from camshaft position sensor.

Measure the resistance of harness between camshaft position sensor connector and engine ground.

Connector & terminal

(E15) No. 1 — Engine ground:

Is the resistance more than 100 kΩ?

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



No


CHECK HARNESS BETWEEN CAMSHAFT POSITION SENSOR AND ECM CONNECTOR.

Measure the resistance of harness between camshaft position sensor connector and engine ground.

Connector & terminal

(E15) No. 1 — Engine ground:

Is the resistance less than 10 Ω?

Yes

• Repair ground short circuit in harness between camshaft position sensor and ECM connector.

•
Note

The harness between both connectors are shielded. Repair ground short circuit in harness together with shield.



No


CHECK HARNESS BETWEEN CAMSHAFT POSITION SENSOR AND ECM CONNECTOR.

Measure the resistance of harness between camshaft position sensor connector and engine ground.

Connector & terminal

(E15) No. 2 — Engine ground:

Is the resistance less than 5 Ω?

Yes


No

• 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



CHECK CONDITION OF CAMSHAFT POSITION SENSOR.

Is the camshaft position sensor installation bolt tightened securely?

Yes


No

Tighten camshaft position sensor installation bolt securely.


CHECK CAMSHAFT POSITION SENSOR.

Remove the camshaft position sensor.

Measure the resistance between connector terminals of camshaft position sensor.

Terminals

No. 1 — No. 2:

Is the resistance 1 — 4 kΩ?

Yes


No

Replace the camshaft position sensor.


CHECK CONDITION OF CAMSHAFT POSITION SENSOR.

Turn the ignition switch to OFF.

Is the camshaft position sensor installation bolt tightened securely?

Yes


No

Tighten camshaft position sensor installation bolt securely.


CHECK CAM SPROCKET.

Remove the timing belt cover.

Are cam sprocket teeth cracked or damaged?

Yes

Replace the cam sprocket.


No


CHECK INSTALLATION CONDITION OF TIMING BELT.

Turn the camshaft using ST, and align alignment mark on cam sprocket with alignment mark on timing belt cover LH.

ST 32005170 CAMSHAFT SOCKET

Is the timing belt dislocated from its proper position?

Yes

Repair installation condition of timing belt.


No

Replace the camshaft position sensor.
