WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITION & POSSIBLE CAUSES

DTC P0662:00	Variable intake air solenoid valve circuit high input
DETECTION CONDITION	The PCM monitors the variable intake air solenoid valve control signal If the PCM turns the variable intake air solenoid valve on but current at the PCM terminal still remains high, the PCM determines that the variable intake air solenoid valve circuit has malfunction Diagnostic support note This is a continuous monitor (other). The MIL does not illuminate. FREEZE FRAME DATA is not available The DTC is stored in the PCM memory
POSSIBLE CAUSE	Variable intake air solenoid valve connector or terminal malfunction PCM connector or terminal malfunction Short to power supply in wiring harness between variable intake air solenoid valve terminal B and PCM terminal 2J Variable intake air solenoid valve malfunction PCM malfunction
