No you can't just push it back
afaik...it's a stepper motor with about 20 steps from fully closed to fully open.
It's the plug end that's loose on yours is it? That's what I'm gathering from your posts.
Here's how to test it:
An
IAC motor can fail one of two ways, either the motor short circuits and stops working or the motor will develop high resistance and cause the
IAC control motor to react slowly, either failure can cause the engine to stall at idle. When a trouble code scan is performed it sometimes won't always detect a failed or weak
IAC motor.
To check the
IAC motor remove the unit, with the wires connected turn the key to the "on" position without starting the engine, the
IAC should move in or out.
If the
IAC motor does nothing it has probably failed, replace it with a new unit and recheck the system.
Note: whilst the
IAC motor is removed clean (use aerosol carburetor/ throttle body cleaner) the passages the
IAC uses to control idle air speed, also inspect the
IAC for a build-up on the seating (pointed) end and clean as necessary.
