WARNING: This page is about a different car, the 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
PCM monitors Variable Air Duct (VAD) solenoid control signal at PCM 104-pin harness connector terminal No. 42. If PCM detects VAD solenoid control signal does not change when VAD solenoid valve is switched to ON or OFF, PCM determines VAD solenoid control circuit has a malfunction. This is a Continuous Monitor (other). MIL does not illuminate. PENDING CODE is available if PCM detects malfunction condition during first drive cycle. FREEZE FRAME DATA is available. DTC is stored in PCM memory.
