| DETECTION CONDITION |
- The PCM monitors the input signal from the KS when the engine is running. If the input voltage is above 4.8 V
for 5 s
, the PCM determines that the KS circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
