F–130 ON-BOARD DIAGNOSTIC End Of Sie DTC P0335 A6E397001085W05 6 VERIFY TROUBLESHOOTING OF DTC P0328 • Make sure to connect all disconnected connectors. • Clear DTC from PCM memory using WDS or equivalent. • Perform KOEO/KOER self-test. .) • Is same DTC present? Yes Replace PCM, then go to next step. (See No Go to next step. 7 VERIFY AFTER REPAIR PROCEDURE • Perform “After Repair Procedure”. • Is there any DTC present? Yes Go to applicable DTC troubleshooting. (See .) No Troubleshooting completed. STEP INSPECTION ACTION 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 2.0 g/s {0.26 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 • CKP sensor pulse wheel malfunction • Both CKP sensor wires are shorted each other |
