DTC P0335 [LF]: Notes

DTC P0335 (LF) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0335	CKP sensor circuit problem
DETECTION CONDITION	If the PCM does not receive the input voltage from the CKP sensor for 4.2 s while the MAF is 1.95 g/s {0.2 lb/min.} or above , the PCM determines that the CKP sensor circuit has a malfunction. If a malfunction is detected in the input pulse pattern from the CKP sensor. Diagnostic support note This is a continuous monitor (CCM). The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2/Mode 12) is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	CKP sensor connector or terminals malfunction Short to ground in wiring harness between CKP sensor terminal C and PCM terminal 2AQ Short to ground in wiring harness between CKP sensor terminal B and PCM terminal 2W PCM connector or terminals malfunction Short to power supply in wiring harness between CKP sensor terminal C and PCM terminal 2AQ Short to power supply in wiring harness between CKP sensor terminal B and PCM terminal 2W CKP sensor circuits are shorted to each other Open circuit in wiring harness between CKP sensor terminal B and PCM terminal 2W Open circuit in wiring harness between CKP sensor terminal A and PCM terminal 2AB CKP sensor malfunction CKP sensor pulse wheel malfunction PCM malfunction
