DTC P0327 KS circuit low input

DETECTION CONDITION

• The PCM monitors the input voltage from the KS when the engine is running. If the input voltage is less than 1.2 V, the PCM determines that the KS circuit input voltage is low.

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.
• PENDING CODE is available if the PCM detects the above malfunction condition.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• KS malfunction
• Connector or terminal malfunction
• Open circuit in wiring harness between KS terminal A and PCM terminal 1T
• Short to GND in wiring harness between KS terminal A and PCM terminal 1T
• Open circuit in wiring harness between KS terminal B and PCM terminal 1F
• Short to GND in wiring harness between KS terminal B and PCM terminal 1F
• PCM malfunction
