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): ― CKP sensor terminal A ― CKP sensor terminal B • 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: ― CKP sensor connector terminal C (harness-side) ― CKP sensor connector terminal B (harness-side) • 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: ― CKP sensor terminal A (harness-side) and PCM terminal 2H (harness-side) ― CKP sensor terminal B (harness-side) and PCM terminal 2C (harness-side) ― CKP sensor terminal C (harness-side) and main relay • 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. (See CRANKSHAFT POSITION (CKP) SENSOR INSPECTION [L3 Turbo].) • 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. Note • The 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 [L3 Turbo].)
No | Go to the next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L3 Turbo].)
No | Troubleshooting completed.
