DTC P0335[L3 WITH TC]

DTC P0335 CKP sensor circuit malfunction
• 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
DETECTION
• This is a continuous monitor (CCM).
CONDITION
• 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.
• CKP sensor malfunction
• Connector or terminal malfunction
• CKP sensor is dirty.
• Short to the power supply between CKP sensor terminal A and PCM terminal 2P
• Short to the power supply between CKP sensor terminal B and PCM terminal 2W
• Short to ground between CKP sensor terminal C and main relay
POSSIBLE
• Short to ground between CKP sensor terminal B and PCM terminal 2W
CAUSE
• Open circuit between CKP sensor terminal A and PCM terminal 2P
• Open circuit between CKP sensor terminal B and PCM terminal 2W
• Open circuit between CKP sensor terminal C and main relay
