DTC P0335 [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed))

BME010200100W19

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". (See AFTER REPAIR PROCEDURE [AJ].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed)).)
No | Troubleshooting completed.
