It should be a PWM valve, if there are no different IAC valves used in the 7A-FE. I've tried hard to find out more about it, especially the working frequency. This is what i found:
QUOTE The ECM varies the on time (duty ratio) for each coil. The difference in
strength between the two magnetic fields determines the position of the valve. The frequency is very high, 250Hz. This high frequency helps the valve maintain the correct position for proper air flow. |
