DTC P0335 [L3]

BME010200300217

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 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 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 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 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 off
• Disconnect CKP sensor connector.
• Turn the ignition switch to the ON position (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 the next step.
6
INSPECT CKP CIRCUIT FOR SHORT TO GROUND
• Inspect for continuity between 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 suspected harness, then go to Step 11.
No
Go to the next step.
7
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 suspected harness, then go to Step 11.
No
Go to the next step.
8
INSPECT POOR CONNECTION OF PCM CONNECTOR
• Disconnect PCM connector.
• Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.).
• Is there malfunction?
Yes
Repair terminal, then go to Step 11.
No
Go to the next step.
9
INSPECT CKP CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between following circuits:
- CKP sensor terminal A (wiring harness-side) and PCM terminal 2D (wiring harness-side)
- CKP sensor terminal B (wiring harness-side) and PCM terminal 2G (wiring 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 the ignition switch off.
• Perform CKP sensor inspection.
• Is CKP sensor normal?
Yes
Check CKP sensor pulse wheel for damage. Replace CKP sensor pulse wheel and go to the next step.
No
Replace the CKP sensor, then 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 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 the next step.
No
Go to the next step.
12
VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
• Is there DTC present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
