DTC P0335 [ZY]


DTC P0335	CKP sensor circuit problem
DETECTION CONDITION	• If the PCM does not receive the input voltage from the CKP sensor for 4.2 s or more while the MAF is 1.43 g/s {0.189 lb/min} or more, the PCM determines that there is a CKP sensor circuit problem. • If a malfunction is detected in the input pulse pattern from the CKP sensor. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• CKP sensor malfunction • Connector or terminal malfunction • Open circuit in wiring harness between CKP sensor terminal A and PCM terminal 2I • Short to ground in wiring harness between CKP sensor terminal A and PCM terminal 2I • Open circuit in wiring harness between CKP sensor terminal B and PCM terminal 2Y • Short to power supply in wiring harness between CKP sensor terminal B and PCM terminal 2Y • Short to ground in wiring harness between CKP sensor terminal B and PCM terminal 2Y • Open circuit in wiring harness between CKP sensor terminal C body ground • Crankshaft pulley malfunction • PCM malfunction


STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service 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.
2		No	Go to the next step.
3	INSPECT CKP SENSOR CONNECTOR FOR POOR CONNECTION • Turn the ignition switch 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 terminal, then go to Step 9.
3		No	Go to the next step.
4	INSPECT CKP SENSOR CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Inspect for continuity between the following terminals: - CKP sensor terminal B (wiring harness-side) and body ground - CKP sensor terminal A (wiring harness-side) and body ground • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to Step 9.
4		No	Go to the next step.
5	INSPECT CKP SENSOR CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between CKP sensor terminal B (wiring harness-side) and body ground. • Is the voltage B+?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
5		No	Go to the next step.
6	INSPECT CKP SENSOR • Inspect the CKP sensor. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [ZY].) • Is there any malfunction?	Yes	Replace the CKP sensor, then go to Step 9. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION [ZY].)
6		No	Go to the next step.
7	INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 9.
7		No	Go to the next step.
8	INSPECT CKP SENSOR CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect for continuity between the following terminals: - CKP sensor terminal A (wiring harness-side) and PCM terminal 2I (wiring harness-side) - CKP sensor terminal B (wiring harness-side) and PCM terminal 2Y (wiring harness-side) • Is there continuity?	Yes	Go to the next step.
8		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
9	VERIFY TROUBLESHOOTING OF DTC P0335 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Run the engine for 4.2 s or more when the MAF PID is 1.43 g/s {0.189 lb/min} or more. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [ZY].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [ZY].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [ZY].)
10		No	DTC troubleshooting completed.
