DTC P0335 [L3 Turbo]
id0102b7806900
DTC P0335 |
CKP sensor circuit malfunction |
---|---|
DETECTION CONDITION
|
• If the PCM does not receive the input voltage from the CKP sensor for 4.2 s while the MAF is 2.0 g/s {0.26 lb/min.} or above, the PCM determines that the CKP sensor circuit has a malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if the PCM detects the above malfunction condition during first drive cycle.
• FREEZE FRAME DATA is available.
• DTCs are stored in the PCM memory.
|
POSSIBLE CAUSE
|
• CKP sensor malfunction
• Connector or terminal malfunction
• CKP sensor is dirty.
• Short to the power supply between CKP sensor terminal A and PCM terminal 2H
• Short to the power supply between CKP sensor terminal B and PCM terminal 2C
• Short to ground between CKP sensor terminal C and main relay
• Short to ground between CKP sensor terminal B and PCM terminal 2C
• Open circuit between CKP sensor terminal A and PCM terminal 2H
• Open circuit between CKP sensor terminal B and PCM terminal 2C
• Open circuit between CKP sensor terminal C and main relay
• CKP sensor pulse wheel malfunction
• Both CKP sensor wires are shorted to each other
• PCM malfunction

Diagnostic procedure
STEP |
INSPECTION |
ACTION |
|
---|---|---|---|
1
|
VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded?
|
Yes
|
Go to the next step.
|
No
|
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
|
||
2
|
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Verify related Service Information availability.
• Is any related Service Information available?
|
Yes
|
Perform repair or diagnosis according to the available Service information.
If the vehicle is not repaired, go to the next step.
|
No
|
Go to the next step.
|
||
3
|
INSPECT CKP SENSOR CONNECTOR FOR POOR CONNECTION
• 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 10.
|
||
4
|
INSPECT CKP CIRCUIT FOR SHORT TO POWER SUPPLY
• Turn ignition switch OFF
• Disconnect the CKP sensor connector.
• Turn ignition switch to the ON position (Engine off).
• Measure the voltage between following terminals (harness-side):
• Is there any voltage?
|
Yes
|
Repair or replace the suspected wiring harness, then go to Step 10.
|
No
|
Go to the next step.
|
||
5
|
INSPECT CKP CIRCUIT FOR SHORT TO GROUND
• Inspect for continuity between following terminal and body ground:
• Is there continuity?
|
Yes
|
Repair or replace the suspected wiring harness, then go to Step 10.
|
No
|
Go to the next step.
|
||
6
|
INSPECT CKP CIRCUITS FOR SHORT CIRCUIT
• Inspect for continuity between CKP sensor connector terminals B and C (harness-side).
• Is there continuity?
|
Yes
|
Repair or replace the suspected wiring harness, then go to Step 10.
|
No
|
Go to the next step.
|
||
7
|
INSPECT PCM CONNECTOR FOR POOR CONNECTION
• 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 10.
|
No
|
Go to the next step.
|
||
8
|
INSPECT CKP CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between the following circuits:
• Are there continuity?
|
Yes
|
Go to the next step.
|
No
|
Repair or replace the suspected wiring harness, then go to Step 10.
|
||
9
|
INSPECT CKP SENSOR
• Turn the ignition switch off.
• Perform the CKP sensor inspection.
• Is the 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.
|
||
10
|
VERIFY TROUBLESHOOTING OF DTC P0335 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Turn ignition switch to the ON position (Engine off).
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Start the engine.
• Access the MAF PID using the WDS or equivalent.
• Is the same DTC present?
|
Yes
|
Replace the PCM, then go to the next step.
|
No
|
Go to the next step.
|
||
11
|
VERIFY AFTER REPAIR PROCEDURE
• Perform the “After Repair Procedure”.
• Are any DTCs present?
|
Yes
|
Go to the applicable DTC inspection.
(See DTC TABLE [L3 Turbo].)
|
No
|
Troubleshooting completed.
