Detection Condition

DTC is set when PCM detects low voltage input from Variable Tumble Control System (VTCS) solenoid valve when VTCS solenoid valve is off. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition in 2 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.
