DTC P0335 [L3]

BME010200300W05

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 1.95 g/s {0.25 lb/min.} or above, PCM determines that 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 between CKP sensor terminal A to PCM terminal 2D • Short to power between CKP sensor terminal B to PCM terminal 2G
• Short to ground between CKP sensor terminal A to PCM terminal 2D
• Short to ground between CKP sensor terminal B to PCM terminal 2G
• Open circuit between CKP sensor terminal A to PCM terminal 2D
• Open circuit between CKP sensor terminal B to PCM terminal 2G
• Both CKP sensor wires short each other.
• 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 next step.
No | Record FREEZE FRAME DATA on repair order, then go to 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 next step.
No | Go to next step.
3 | VERIFY CKP SENSOR VOLTAGE • Disconnect CKP sensor connector. • Connect voltmeter between CKP sensor connector terminals A and B (sensor-side). • Inspect the voltage in AC range while cranking the engine. • Is there any voltage reading? | Yes | Go to 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 connector okay? | Yes | Go to next step.
No | Reconnect the connector, then go to Step 11.
5 | INSPECT CKP CIRCUIT FOR SHORT TO POWER • Turn ignition key to OFF • Disconnect CKP sensor connector. • Turn ignition key to ON (Engine OFF). • Measure voltage between following terminals

  - CKP sensor terminal A
  - CKP sensor terminal B

• Is there any voltage reading?
Yes
Repair or replace suspected harness, then go to Step 11.
No | Go to next step.
6 | INSPECT CKP CIRCUIT FOR SHORT TO GROUND • Inspect 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 next step.
7 | INSPECT CKP CIRCUITS FOR SHORTS • Inspect 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 next step.
8 | INSPECT POOR CONNECTION OF PCM CONNECTOR • Disconnect PCM connector. • Check for poor connection (damaged, pulled-out terminals, corrosion, etc.). • Is there malfunction? | Yes | Repair terminal, then go to Step 11.
No | Go to next step.
9 | INSPECT CKP CIRCUIT FOR OPEN CIRCUIT • Inspect continuity between following circuits:

  - CKP sensor terminal A (harness-side) and PCM terminal 2D (harness-side)
  - CKP sensor terminal B (harness-side) and PCM terminal 2G (harness-side)

• Is there continuity?
Yes
Go to Step 11.
No | Repair or replace suspected harness, then go to Step 11.
10 | INSPECT CKP SENSOR • Turn ignition key to OFF. • Perform CKP sensor inspection. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [L3].) • Is CKP sensor okay? | Yes | Go to next step.
No | Check CKP sensor pulse wheel for damage. Replace CKP sensor pulse wheel and go to Step 10.
11 | VERIFY TROUBLESHOOTING OF DTC P0335 COMPLETED • Make sure to reconnect all disconnected connectors. • Turn ignition key to ON (Engine OFF). • Clear DTC from PCM memory using WDS or equivalent. • Start engine.
• Access MAF PID using WDS or equivalent.

  Note

  • MAF PID should indicate 1.95 g/s {0.25 lb/min.} or above during this test

• Is same DTC present?
Yes
Replace PCM, then go to next step.
(See PCM REMOVAL/INSTALLATION [L3].)
No | Go to next step.
12 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [L3].) • Is there DTC present? | Yes | Go to applicable DTC troubleshooting. (See DTC TABLE [L3].)
No | Troubleshooting completed.
