DTC P0335 | CKP sensor circuit malfunction
--- | ---
DETECTION CONDITION | • If the PCM does not receive input voltage from the CKP sensor for 4.2 s or more while the MAF is 1.43 g/s {0.189 lb/min} or more, the PCM determines that the CKP sensor circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle. • The PENDING CODE is available if the PCM detects the above malfunction condition. • The FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE | • CKP sensor malfunction • Connector or terminal malfunction • The CKP sensor is dirty. • Short to power between CKP sensor terminal B and PCM terminal 2P • Short to ground between CKP sensor terminal B and PCM terminal 2P • Open circuit between CKP sensor terminal B and PCM terminal 2P • Open circuit between CKP sensor terminal A and PCM terminal 2T • Open circuit between CKP sensor terminal C and body ground • CKP sensor pulse wheel malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the 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 SERVICE INFORMATION AVAILABILITY • Check for related Service Information availability. • Is any related Service Information available? | Yes | Perform the 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 FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the CKP sensor connector. • Check for poor connection (such as damaged, pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 10.
No | Go to the next step.
4 | INSPECT POWER SUPPLY CIRCUIT AT CKP SENSOR CONNECTOR • Turn the ignition switch to the ON position (Engine OFF). • Measure the voltage between CKP sensor terminal A (wiring harness-side) and body ground. • Is the voltage approx. 5 V? | Yes | Go to the next step
No | Repair or replace the harness for an open circuit or short to ground, then go to Step 10.
5 | INSPECT CKP SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for check continuity between CKP sensor terminal B (wiring harness-side) and PCM terminal 2P (wiring harness-side). • Is there continuity? | Yes | Go to the next step
No | Repair or replace the harness for an open circuit, then go to Step 10.
6 | INSPECT CKP SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER • Turn the ignition switch to the ON position (engine OFF). • Measure the voltage between CKP sensor terminal B (wiring harness-side) and body ground. • Is the voltage B+? | Yes | Repair or replace the harness for short to power, then go to Step 10.
No | Go to the next step.
7 | INSPECT CKP SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Inspect for check continuity between CKP sensor terminal B (wiring harness-side) and body ground. • Is there continuity? | Yes | Repair or replace the harness for short to ground, then go to Step 10.
No | Go to the next step.
8 | INSPECT CKP SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT • Inspect for check continuity between CKP sensor terminal C (wiring harness-side) and body ground. • Is there continuity? | Yes | Go to the next step
No | Repair or replace for an open circuit, then go to Step 10.
9 | INSPECT CKP SENSOR • Inspect for a check pulsation signal coming from PCM terminal 2P (wiring harness-side) while cranking the engine. • Is there any signal? | Yes | Go to the next step.
No | Inspect the check crankshaft pulley for damage. Replace the crankshaft pulley, then go to the next step.
10 | 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 the engine. • Access MAF PID using the WDS or equivalent. Note • The MAF PID should indicate 1.43 g/s {0.189 lb/min} or more during this test • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION.)
No | Go to the next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE.) • Are any DTCs present? | Yes | Go to applicable DTC troubleshooting. (See DTC TABLE.)
No | Troubleshooting completed.
