Honda Fit City Corolla 1.8 Idle Air Control Motor 16022-PWA-G01 22270-0D040

For Honda Fit, City, and Corolla 1.8L models, idle air control valve (OEM numbers: 16022-PWA-G01 / 22270-0D040) mounted on the side of the throttle body precisely controls idle intake to stabilize engine speed. When idle is unstable, fluctuates, or starting is easy to stall or the engine RPM drops after releasing the accelerator, internal carbon buildup or motor sticking may require replacement. Installation difficulty moderate; estimated time 0.5-1 hour; calibrate the throttle position sensor during installation.
