P1522 MAZDA MeaningThree solenoid-operated shutter valves are installed in the dynamic chamber of the Variable Resonance Induction System (VRIS). The VRIS opens and closes the shutter valves according to the engine speed and throttle opening angle to improve the charging efficiency by utilizing the pressure waves of the intake air There are two vacuum chambers located under the front (LH) bank of the intake manifold. These vacuum chambers maintain a constant supply of vacuum to the VRIS shutter valves during wide-open throttle operation and other low-vacuum, low-speed situations. The Diagnostic Trouble Code (DTC) is set when the Powertrain Control Module (PCM) detects low input voltage from VRIS solenoid valve No. 1 system with ignition switch on. This is a continuous monitor. MIL will not illuminate.
