DTC P0335 (No.23): Crankshaft Position (CKP) Sensor Circuit Malfunction

Wiring Diagram

1.	CKP sensor	*:	Vehicle equipped with immobilizer control system
2.	ECM

Reference

Connect oscilloscope between “E115-23 (E115-15)” and “E115-1” terminals of ECM connector connected to ECM and check CKP sensor signal referring to “Reference waveform No.11” in Inspection of ECM and Its Circuits:M13A without VVT and “Reference waveform No.12” in Inspection of ECM and Its Circuits:M13A without VVT .

DTC Detecting Condition and Trouble Area

DTC detecting condition	Trouble area
• NO CKP sensor signal for 2 seconds at engine cranking.	• CKP sensor circuit open or short. • Signal teeth damaged. • CKP sensor malfunction, foreign material being attached or improper installation. • ECM malfunction.

DTC Confirmation Procedure

1) Clear DTC and crank engine for 2 sec.

2) Select “DTC” mode on scan tool and check DTC.

DTC Troubleshooting

Step	Action	YES	NO
1	Was “Engine and Emission Control System Check” performed?	Go to Step 2.	Go to Engine and Emission Control System Check:M13A without VVT .
2	Check CKP Sensor and connector for proper installation Is CKP sensor installed properly and connector connected securely?	Go to Step 3.	Correct.
3	Check wire harness and connection 1) Disconnect connector from CKP sensor. 2) Check for proper connection to CKP sensor at each terminal. 3) If OK, turn ignition switch ON and check for voltage at each terminal of sensor connector disconnected. Terminal “B+”: 10 – 14 V Terminal “Vout”: 4 – 5 V Terminal “GND”: 0 V Is check result satisfactory?	Go to Step 5.	Go to Step 4.
4	Was terminal “Vout” voltage out of specification in Step 3 check?	“GRN/RED” wire open, short or poor connection. If wire and connection are OK, substitute a known-good ECM and recheck.	“BLU/BLK” or “BLK” wire open, short or poor connection.
5	Check ground circuit for open 1) Turn ignition switch OFF. 2) Check for continuity between “GND” terminal of CKP sensor connector and engine ground. Is continuity indicated?	Go to Step 6.	“BLK” wire open or poor ground connection.
6	Check CKP sensor for operation 1) Check CKP sensor and signal rotor referring to Crankshaft Position (CKP) Sensor Inspection:M13A . Is it in good condition?	Substitute a known-good ECM and recheck.	Clean or replace rotor teeth or replace CKP sensor.
