WARNING: This page is about a different variant/trim than selected.
PCM monitors Variable Intake-air System (VIS) control solenoid valve control signal at PCM 30-pin harness connector terminal "4R". If PCM turns VIS control solenoid valve on but voltage at PCM 30-pin harness connector terminal "4R" still remains high, PCM determines VIS control solenoid valve circuit has malfunction.
