DTC P0335 CRANKSHAFT POSITION SENSOR “A” CIRCUIT

DTC P0335 CRANKSHAFT POSITION SENSOR “A” CIRCUIT

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 HARNESS BETWEEN CRANKSHAFT POSITION SENSOR AND ECM CONNECTOR.

Turn the ignition switch to OFF.

Disconnect the connector from crankshaft position sensor.

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

Connector & terminal

(E10) 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 crankshaft position sensor and ECM connector

• Poor contact in ECM connector

• Poor contact in coupling connector



No


CHECK HARNESS BETWEEN CRANKSHAFT POSITION SENSOR AND ECM CONNECTOR.

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

Connector & terminal

(E10) No. 1 — Engine ground:

Is the resistance less than 10 Ω?

Yes

• Repair ground short circuit in harness between crankshaft 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 CRANKSHAFT POSITION SENSOR AND ECM CONNECTOR.

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

Connector & terminal

(E10) 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 crankshaft position sensor and ECM connector

• Poor contact in ECM connector

• Poor contact in coupling connector



CHECK CONDITION OF CRANKSHAFT POSITION SENSOR.

Is the crankshaft position sensor installation bolt tightened securely?

Yes


No

Tighten crankshaft position sensor installation bolt securely.


CHECK CRANKSHAFT POSITION SENSOR.

Remove the crankshaft position sensor.

Measure the resistance between connector terminals of crankshaft position sensor.

Terminals

No. 1 — No. 2:

Is the resistance 1 — 4 kΩ?

Yes

Repair poor contact in crankshaft position sensor connector.


No

Replace the crankshaft position sensor.
