DTC P0335 CRANKSHAFT POSITION SENSOR “A” CIRCUIT

DTC DETECTING CONDITION:

Immediately at fault recognition

TROUBLE SYMPTOM:

• Engine stalls.

• Failure of engine to start

CAUTION:

After repairing or replacing the defective part, perform the Clear Memory Mode and Inspection Mode .

WIRING DIAGRAM:

STEPCHECKYESNO

1.CHECK CONDITION OF CRANKSHAFT POSITION SENSOR.

Is the crankshaft position sensor installation bolt tightened securely?

Tighten the crankshaft position sensor installation bolt securely.

2.CHECK CRANKSHAFT POSITION SENSOR.

1) Turn the ignition switch to OFF.

2) Remove the crankshaft position sensor.

3) Measure the resistance between terminals of crankshaft position sensor.

Terminals

No. 1 — No. 2:

Is the resistance 1 — 4 kΩ?

Replace the crankshaft position sensor.

3.CHECK HARNESS BETWEEN ECM AND CRANKSHAFT POSITION SENSOR.

1) Disconnect the connectors from the ECM.

2) Measure the resistance of harness between the ECM and crankshaft position sensor connector.

Connector & terminal

(B137) No. 29 — (E10) No. 1:

(B137) No. 30 — (E10) No. 2:

Is the resistance less than 1 Ω?

Repair the poor contact of the ECM and crankshaft position sensor connector.

Repair the harness and connector.

NOTE:

In this case, repair the following item:

• Open circuit of harness between ECM and crankshaft position sensor connector

• Poor contact of coupling connector
