DTC P0328:00

KS circuit high input

DETECTION CONDITION
•  The PCM monitors the input signal from the KS when the engine is running. If the input voltage is above 4.8 Vthe PCM determines that KS circuit has a malfunction.
Diagnostic support note
•  This is a continuous monitor (CCM).
•  MIL illuminates if the PCM detects the above malfunction conditions during first drive cycle.
•  FREEZE FRAME DATA is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  KS malfunction
•  Connector or terminal malfunction
•  Short to power supply in wiring harness between KS terminal A and PCM terminal 2U
•  Short to power supply in wiring harness between KS terminal B and PCM terminal 2V
•  PCM malfunction
