DTC P0335 | CKP sensor circuit problem
--- | ---

DETECTION CONDITION

• If the PCM does not receive input voltage from the CKP sensor for 4.2 s while MAF is 2.0 g/s {0.26 lb/min} or above, the PCM determines that the CKP sensor circuit has 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 available if 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 power supply in wiring harness between CKP sensor terminal A to PCM terminal 2Y
• Short to power supply in wiring harness between CKP sensor terminal B to PCM terminal 2Z
• Short to ground in wiring harness between CKP sensor terminal A to PCM terminal 2Y
• Short to ground in wiring harness between CKP sensor terminal B to PCM terminal 2Z
• Open circuit in wiring harness between CKP sensor terminal A to PCM terminal 2Y
• Open circuit in wiring harness between CKP sensor terminal B to PCM terminal 2Z
• CKP sensor pulse wheel malfunction
• Both CKP sensor wires are shorted each other

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 the FREEZE FRAME DATA on repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service repair information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to 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 the CKP sensor connector. • Connect voltmeter between CKP sensor terminals A and B (sensor-side). • Inspect 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 POOR CONNECTION OF CKP SENSOR CONNECTOR • 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.

5

INSPECT CKP CIRCUIT FOR SHORT TO POWER
• Turn the ignition switch to off.
• Disconnect the CKP sensor connector.
• Turn the ignition switch to the ON position (Engine off).
• Measure the voltage between following terminals

  - CKP sensor terminal A
  - CKP sensor terminal B

• Is any voltage reading?

Yes

Repair or replace the wiring harness, then go to Step 11.

No | Go to the next step.

6

INSPECT CKP CIRCUIT FOR SHORT TO GROUND
• Inspect for continuity between following terminal and body ground:

  - CKP sensor terminal A (wiring harness-side)
  - CKP sensor 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.
7 | INSPECT CKP CIRCUITS FOR SHORTS • Inspect for continuity between CKP sensor 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 the next step.
8 | INSPECT POOR CONNECTION OF PCM CONNECTOR • 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 11.
No | Go to the next step.

9

INSPECT CKP CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between following terminals:

  - CKP sensor terminal A (wiring harness-side) and PCM terminal 2Y (wiring harness-side)
  - CKP sensor terminal B (wiring harness-side) and PCM terminal 2Z (wiring harness-side)

• Is there continuity?

Yes

Go to Step 11.

No | Repair or replace the suspected wiring harness, then go to Step 11.
10 | INSPECT CKP SENSOR • Turn the ignition switch off. • Perform CKP sensor inspection. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [LF]) • Is CKP sensor normal? | Yes | Go to the next step.
No | Inspect the CKP sensor pulse wheel for damage. Replace the CKP sensor pulse wheel and go to the next step.

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 2.0 g/s {0.26 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 [LF].)

No | Go to the next step.
12 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [LF].) • Are any DTC present? | Yes | Go to the applicable DTC troubleshooting. (See DTC TABLE [LF].)
No | Troubleshooting completed.
