DTC P1569: Variable Tumble Control System (VTCS) Solenoid Valve Circuit, Low Input: Condition

DTC is set when Powertrain Control Module (PCM) detects low voltage from VICS solenoid valve with VICS solenoid valve off. This is a continuous monitor. MIL is illuminated when Powertrain Control Module (PCM) detects malfunction during two consecutive drive cycles. Possible causes are:

• Open or Short circuit between VICS solenoid valve and PCM.
• Open circuit between VICS solenoid valve and main relay.
• VICS solenoid valve malfunction.
• PCM malfunction.
