DTC P0335


DTC P0335	CKP sensor circuit malfunction
DETECTION CONDITION	• If the PCM does not receive 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 the CKP sensor circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle. • The PENDING CODE is available if the PCM detects the above malfunction condition. • The FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• CKP sensor malfunction • Connector or terminal malfunction • The CKP sensor is dirty. • Short to power between CKP sensor terminal B and PCM terminal 2P • Short to ground between CKP sensor terminal B and PCM terminal 2P • Open circuit between CKP sensor terminal B and PCM terminal 2P • Open circuit between CKP sensor terminal A and PCM terminal 2T • Open circuit between CKP sensor terminal C and body ground • CKP sensor pulse wheel malfunction


STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Check for related Service Information availability. • Is any related Service Information available?	Yes	Perform the 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 FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the CKP sensor connector. • Check for poor connection (such as damaged, pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 10.
3		No	Go to the next step.
4	INSPECT POWER SUPPLY CIRCUIT AT CKP SENSOR CONNECTOR • Turn the ignition switch to the ON position (Engine OFF). • Measure the voltage between CKP sensor terminal A (wiring harness-side) and body ground. • Is the voltage approx. 5 V?	Yes	Go to the next step
4		No	Repair or replace the harness for an open circuit or short to ground, then go to Step 10.
5	INSPECT CKP SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for check continuity between CKP sensor terminal B (wiring harness-side) and PCM terminal 2P (wiring harness-side). • Is there continuity?	Yes	Go to the next step
5		No	Repair or replace the harness for an open circuit, then go to Step 10.
6	INSPECT CKP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER • 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 harness for short to power, then go to Step 10.
6		No	Go to the next step.
7	INSPECT CKP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Inspect for check continuity between CKP sensor terminal B (wiring harness-side) and body ground. • Is there continuity?	Yes	Repair or replace the harness for short to ground, then go to Step 10.
7		No	Go to the next step.
8	INSPECT CKP SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT • Inspect for check continuity between CKP sensor terminal C (wiring harness-side) and body ground. • Is there continuity?	Yes	Go to the next step
8		No	Repair or replace for an open circuit, then go to Step 10.
9	INSPECT CKP SENSOR • Inspect for a check pulsation signal coming from PCM terminal 2P (wiring harness-side) while cranking the engine. • Is there any signal?	Yes	Go to the next step.
9		No	Inspect the check crankshaft pulley for damage. Replace the crankshaft pulley, then go to the next step.
10	VERIFY TROUBLESHOOTING OF DTC P0335 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to the ON position (Engine off). • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Access MAF PID using the WDS or equivalent. Note • The MAF PID should indicate 1.43 g/s {0.189 lb/min} or more during this test • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION.)
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE.) • Are any DTCs present?	Yes	Go to applicable DTC troubleshooting. (See DTC TABLE.)
11		No	Troubleshooting completed.
