Automotive Technology Course | IAC Valve and Min Air Rate Adj.

The IAC is the air control valve, which also determines the idle and is directly related to the minimum air rate adjustment. This video describes the operation and procedures to adjust the minimum air-rate. If this adjustment is done wrong it'll have a detrimental impact on idle speed and general engine operation, resulting in the vehicle stalling at a red light or stop sign.

Minimum air rate also has a huge effect on air fuel ratio, which when performed incorrectly will render the air fuel mixture lean, causing a fuel trim imbalance (fuel injection). Shown here using extensive CG animation and a real technician with a hands on approach. Presented as part of an automotive technology course.
