DTC P0335

CKP sensor circuit malfunction

DETECTION CONDITION

• If PCM does not receive input voltage from CKP sensor for 4.2 s while MAF is 2.0 g/s {0.26 lb/min} or above, PCM determines that 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 condition in the first drive cycle.
• PENDING CODE is available if the PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• DTC is stored in the PCM memory.

POSSIBLE CAUSE

• CKP sensor malfunction
• Connector or terminal malfunction
• CKP sensor is dirty.
• Short to ground between CKP sensor terminal A to PCM terminal 27
• Short to ground between CKP sensor terminal B to PCM terminal 1
• Short to power circuit between CKP sensor terminal A to PCM terminal 27
• Short to power circuit between CKP sensor terminal B to PCM terminal 1
• Open circuit between CKP sensor terminal A to PCM terminal 27
• Open circuit between CKP sensor terminal B to PCM terminal 1
• CKP sensor pulse wheel malfunction
• Both CKP sensor wires are shorted each other
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record FREEZE FRAME DATA on repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Check for related Service Information 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
VERIFY CKP SENSOR VOLTAGE
• Disconnect CKP sensor connector.
• Connect voltmeter between CKP sensor connector terminals A and B (sensor-side).
• Check the voltage in AC range while cranking the engine.
• Is any voltage reading?
Yes
Go to the next step.
No
Go to step 10.
4
CHECK CKP CIRCUIT RESISTANCE
• Turn the ignition switch off.
• Inspect the CKP sensor.
• Is the CKP sensor normal?
Yes
Check CKP sensor pulse wheel for damage. Replace CKP sensor pulse wheel and go to Step 11.
No
If tester reads 0 ohm, then go to the next step.
If tester reads infinity, then go to Step 7.
5
INSPECT CKP CIRCUIT FOR SHORT TO GROUND
• Disconnect CKP sensor connector.
• Check continuity between following terminal and body ground:
- CKP sensor connector terminal A (harness-side)
- CKP sensor connector terminal B (harness-side)
• Is there continuity?
Yes
Repair or replace suspected harness, then go to Step 11.
No
Go to the next step.
6
INSPECT CKP CIRCUITS FOR SHORT CIRCUIT
• Check continuity between CKP sensor connector terminals A and B (harness-side).
• Is there continuity?
Yes
Repair or replace suspected harness, then go to Step 11.
No
Go to step 9.
7
INSPECT POOR CONNECTION OF CKP SENSOR CONNECTOR
• Verify that the CKP sensor connector is connected securely.
• Is connector normal?
Yes
Go to the next step.
No
Reconnect the connector, then go to Step 11.
8
INSPECT CKP CIRCUIT FOR OPEN
• Disconnect CKP sensor connector.
• Connect the PCM connector.
• Check continuity between following circuits:
- CKP sensor terminal A (harness-side) and PCM terminal 27
- CKP sensor terminal B (harness-side) and PCM terminal 1
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace suspected harness, then go to Step 11.
9
INSPECT POOR CONNECTION OF PCM CONNECTOR
• Turn the ignition switch off.
• Disconnect PCM connector.
• Check for poor connection (damaged, pulled-out terminals, corrosion, etc.).
• Is there any malfunction?
Yes
Repair terminal, then go to Step 11.
No
Go to the next step.
10
CHECK CKP SENSOR RESISTANCE
• Inspect the CKP sensor.
• Is the CKP sensor normal?
Yes
Check for poor connection (damaged, pulled-out terminals, corrosion, etc.) or bent terminal of CKP sensor connector.
• Repair if necessary, then go to Step 11.
No
Replace CKP sensor, then go to Step 11.
11
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 engine.
• Access MAF PID using the WDS or equivalent.
Note
• MAF PID should indicate above 2.7 g/s {0.36 lb/min} during this test
• Is same DTC present?
Yes
Replace PCM, then go to the next step.
No
Go to the next step.
12
VERIFY AFTER REPAIR PROCEDURE
• Perform the "After Repair Procedure".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
