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 while the MAF is 1.95 g/s {0.25 lb/min.} or above, the PCM determines that the CKP sensor circuit has a malfunction.

Diagnostic support note

•  This is a continuous monitor (CCM).

•  MIL illuminates if the PCM detects the above malfunction condition during first drive cycle.

•  PENDING CODE is available if the PCM detects the above malfunction condition.

•  FREEZE FRAME DATA is available.

•  DTCs are stored in the PCM memory.

POSSIBLE CAUSE

•  CKP sensor malfunction

•  Connector or terminal malfunction

•  CKP sensor is dirty.

•  Short to the power supply between CKP sensor terminal B and PCM terminal 2W

•  Short to ground between CKP sensor terminal C and PCM terminal 2AQ

•  Short to ground between CKP sensor terminal B and PCM terminal 2W

•  Open circuit between CKP sensor terminal A and body ground

•  Open circuit between CKP sensor terminal B and PCM terminal 2W

•  Open circuit between CKP sensor terminal C and PCM terminal 2AQ

•  CKP sensor pulse wheel malfunction

•  Both CKP sensor wires are shorted to each other

•  PCM malfunction

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 while the MAF is 1.95 g/s {0.25 lb/min.} or above, the PCM determines that the CKP sensor circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • MIL illuminates if the PCM detects the above malfunction condition during first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA is available. • DTCs are stored in the PCM memory.
POSSIBLE CAUSE	• CKP sensor malfunction • Connector or terminal malfunction • CKP sensor is dirty. • Short to the power supply between CKP sensor terminal B and PCM terminal 2W • Short to ground between CKP sensor terminal C and PCM terminal 2AQ • Short to ground between CKP sensor terminal B and PCM terminal 2W • Open circuit between CKP sensor terminal A and body ground • Open circuit between CKP sensor terminal B and PCM terminal 2W • Open circuit between CKP sensor terminal C and PCM terminal 2AQ • CKP sensor pulse wheel malfunction • Both CKP sensor wires are shorted to each other • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service 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 • Verify that the CKP sensor connector is connected securely. • Is connector normal?	Yes	Go to the next step.
3		No	Reconnect the connector, then go to Step 10.
4	INSPECT CKP CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch off • Disconnect the CKP sensor connector. • Turn ignition switch to the ON position (Engine off). • Measure the voltage between following terminals (wiring harness-side): ― CKP sensor terminal B • Is the voltage B+?	Yes	Repair or replace the suspected wiring harness, then go to Step 10.
4		No	Go to the next step.
5	INSPECT CKP CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between following terminal and body ground: ― CKP sensor connector terminal C (wiring harness-side) ― CKP sensor connector terminal B (wiring harness-side) • Is there continuity?	Yes	Repair or replace the suspected wiring harness, then go to Step 10.
5		No	Go to the next step.
6	INSPECT CKP CIRCUITS FOR SHORT CIRCUIT • Inspect for continuity between CKP sensor connector terminals B and C (wiring harness-side). • Is there continuity?	Yes	Repair or replace the suspected wiring harness, then go to Step 10.
6		No	Go to the next step.
7	INSPECT PCM CONNECTOR FOR POOR CONNECTION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair the terminal, then go to Step 10.
7		No	Go to the next step.
8	INSPECT CKP CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between the following circuits: ― CKP sensor terminal A (wiring harness-side) and body ground ― CKP sensor terminal B (wiring harness-side) and PCM terminal 2W (wiring harness-side) ― CKP sensor terminal C (wiring harness-side) and PCM terminal 2AQ • Are there continuity?	Yes	Go to the next step.
8		No	Repair or replace the suspected wiring harness, then go to Step 10.
9	INSPECT CKP SENSOR • Turn the ignition switch off. • Perform the CKP sensor inspection. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [L8, LF, L3]) • Is the CKP sensor normal?	Yes	Go to the next step.
9		No	Inspect the CKP sensor pulse wheel for damage. Replace the CKP sensor pulse wheel and go to the next step.
10	VERIFY TROUBLESHOOTING OF DTC P0335 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn ignition switch to the ON position (Engine off). • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Access the MAF PID using the WDS or equivalent. Note • The MAF PID should indicate 1.95 g/s {0.25 lb/min.} or above during this test • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF, L3].)
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE [L8, LF, L3].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [L8, LF, L3].)
11		No	Troubleshooting completed.
