DTC P0335 [13B-MSP]
DTC P0335 Eccentric shaft position sensor circuit problem
DETECTION
CONDITION
POSSIBLE
CAUSE
The PCM monitors the input signal from the eccentric shaft position sensor when the mass
intake airflow amount is more than 2 g/s {0.26 lb/min}. If the input signal is not input,
the PCM determines that there is an eccentric shaft position sensor circuit malfunction.
Diagnostic support note
This is a continuous monitor (CCM).
The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
FREEZE FRAME DATA (Mode 2/Mode 12) is available.
The DTC is stored in the PCM memory.
