Detection Condition

DTC is set when PCM detects input voltage from Variable Tumble Control System (VTCS) vacuum switch remains high when VTCS solenoid valve is on. PCM determines that VTCS vacuum switch has malfunction. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in two consecutive drive cycles. Pending Code is available if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC is stored in PCM memory.
