DTC P0335:00 [PCM (SKYACTIV-G 2.0)]

DTC P0335:00	CKP sensor circuit problem
DETECTION CONDITION	There is no CKP sensor signal input while the exhaust camshaft rotates 5 times. The CKP sensor input signal pattern, received while the crankshaft rotates 10 times, is incorrect. Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Stops fuel injection Stops ignition
POSSIBLE CAUSE	CKP sensor connector or terminals malfunction Short to ground in wiring harness between the following terminals: CKP sensor terminal A—PCM terminal 1BN CKP sensor terminal C—PCM terminal 1AD PCM connector or terminals malfunction Short to power supply in wiring harness between CKP sensor terminal C and PCM terminal 1AD CKP sensor circuits are shorted to each other Open circuit in wiring harness between the following terminals: CKP sensor terminal A—PCM terminal 1BN CKP sensor terminal C—PCM terminal 1AD CKP sensor terminal B—PCM terminal 1AH CKP sensor malfunction CKP sensor is dirty CKP sensor pulse wheel malfunction PCM malfunction

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION NOTE: Recording can be facilitated using the screen capture function of the PC. Record the FREEZE FRAME DATA/snapshot data on the repair order.	—	Go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
		No	Go to the next step.
3	INSPECT CKP SENSOR CONNECTOR CONDITION Switch the ignition off. Disconnect the CKP sensor connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 10.
		No	Go to the next step.
4	INSPECT CKP SENSOR CIRCUIT FOR SHORT TO GROUND Verify that the CKP sensor connector is disconnected. Inspect for continuity between the following terminals (wiring harness-side) and body ground: CKP sensor terminal A CKP sensor terminal C Is there continuity?	Yes	Disconnect the PCM connector and inspect the wiring harness for short to ground. If the short to ground circuit could be detected in the wiring harness: Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: CKP sensor terminal A—PCM terminal 1BN CKP sensor terminal C—PCM terminal 1AD If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to ground. If the short to ground circuit could not be detected in the wiring harness: Replace the PCM (short to ground in the PCM internal circuit). (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0].) Go to Step 10.
		No	Go to the next step.
5	INSPECT PCM CONNECTOR CONDITION Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 10.
		No	Go to the next step.
6	INSPECT CKP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY Verify that the CKP sensor and PCM connectors are disconnected. Switch the ignition ON (engine off). NOTE: Another DTC may be stored by the PCM detecting an open circuit. Measure the voltage at the CKP sensor terminal C (wiring harness-side). Is the voltage 0 V?	Yes	Go to the next step.
		No	Refer to the wiring diagram and verify whether or not there is a common connector between CKP sensor terminal C and PCM terminal 1AD. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to power supply. Go to Step 10.
7	INSPECT CKP SENSOR CIRCUITS FOR SHORT TO EACH OTHER Verify that the CKP sensor and PCM connectors are disconnected. Switch the ignition off. Inspect for continuity between CKP sensor terminals A, C and B (wiring harness-side). Is there continuity?	Yes	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: CKP sensor terminal A—PCM terminal 1BN CKP sensor terminal C—PCM terminal 1AD CKP sensor terminal B—PCM terminal 1AH If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to each other. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to each other. Go to Step 10.
		No	Go to the next step.
8	INSPECT CKP SENSOR CIRCUIT FOR OPEN CIRCUIT Verify that the CKP sensor and PCM connectors are disconnected. Inspect for continuity between the following terminals (wiring harness-side): CKP sensor terminal A—PCM terminal 1BN CKP sensor terminal C—PCM terminal 1AD CKP sensor terminal B—PCM terminal 1AH Is there continuity?	Yes	Go to the next step.
		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: CKP sensor terminal A—PCM terminal 1BN CKP sensor terminal C—PCM terminal 1AD CKP sensor terminal B—PCM terminal 1AH If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 10.
9	INSPECT CKP SENSOR Inspect the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [SKYACTIV-G 2.0].) Is there any malfunction?	Yes	Replace the CKP sensor, then go to the next step. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)
		No	Go to the next step.
10	VERIFY DTC TROUBLESHOOTING COMPLETED Always reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [PCM (SKYACTIV-G 2.0)].) Start the engine and race it. Perform the KOER self test. (See KOEO/KOER SELF TEST [PCM (SKYACTIV-G 2.0)].) Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0].) Go to the next step.
		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [PCM (SKYACTIV-G 2.0)].) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.0)].)
		No	DTC troubleshooting completed.
