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 2.7 g/s {0.36 lb/min.} or above, PCM determines that CKP sensor circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • MIL illuminates if PCM detects the above malfunction conditions during first drive cycle.
• PENDING CODE is not available.
• 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 21 • Short to ground between CKP sensor terminal B to PCM terminal 22
• Open circuit between CKP sensor terminal A to PCM terminal 21
• Open circuit between CKP sensor terminal B to PCM terminal 22
• CKP sensor pulse wheel 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 SERVICE INFORMATION AVAILABILITY • Check for related Service Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to available Service Information. • If vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | VERIFY CKP SENSOR VOLTAGE • Disconnect the CKP sensor connector. • Connect voltmeter between CKP sensor connector terminals A and B (sensor-side). • Measure 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 | INSPECT CKP SENSOR • Turn the ignition switch off. • Perform CKP sensor inspection. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).)
• Is the CKP sensor normal?
Yes
Inspect the CKP sensor pulse wheel for damage. Replace the 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 the CKP sensor connector. • Inspect for continuity between the following terminal and body ground:

  - CKP sensor connector terminal A (wiring harness-side)
  - CKP sensor connector terminal B (wiring harness-side)

• Is there continuity?
Yes
Repair or replace the wiring harness, then go to Step 11.
No | Go to the next step.
6 | INSPECT CKP CIRCUITS FOR SHORTS • Inspect for continuity between CKP sensor connector terminals A and B (wiring harness-side). • Is there continuity? | Yes | Repair or replace the wiring harness, then go to Step 11.
No | Go to step 9.
7 | INSPECT CKP SENSOR CONNECTOR FOR POOR CONNECTION • Verify that the CKP sensor connector is connected securely. • Is the connector normal? | Yes | Go to the next step.
No | Reconnect the connector, then go to Step 11.
8 | INSPECT CKP CIRCUIT FOR OPEN CIRCUIT • Disconnect the CKP sensor connector. • Disconnect the PCM connector. • Inspect for continuity between following circuits:

  - CKP sensor terminal A (wiring harness-side) and PCM terminal 21
  - CKP sensor terminal B (wiring harness-side) and PCM terminal 22

• Is there continuity?
Yes
Go to the next step.
No | Repair or replace the wiring harness, then go to Step 11.
9 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out terminals, corrosion). • Is there any malfunction? | Yes | Repair the terminal, then go to Step 14.
No | Go to the next step.
10 | INSPECT CKP SENSOR • Perform CKP sensor inspection. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).) • Is the CKP sensor normal? | Yes | Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.) or bent terminal of CKP sensor connector. • Repair if necessary, then go to Step 14.
No | Replace the CKP sensor, then go to Step 14.
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 the engine.
• Access MAF PID using WDS or equivalent.

  Note

  • MAF PID should indicate above 2.7 g/s {0.36 lb/min.} during this test

• Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
No | Go to the next step.
12 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [AJ].) • Is there any DTC present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513).)
No | Troubleshooting completed.
