Mazda throttle adjustment

March 25, 2011
Don't screw around and adjust the TAS at any time

Mazda notes that you should not adjust the throttle adjustment screw (TAS) on fuel injected vehicles with idle speed control motors at any time. The TAS functions as a stopper when the throttle valve is fully closed. During production, the TAS is accurately set by measuring the airflow rate past a closed throttle plate. Any adjustment to this screw will affect PCM control of idle speed.
Tampering with this screw will affect the idle contact switch and/or throttle position sensor settings. Applicable models include 1995-2007 B-series, 1997-2003 Protégé, 1997-2005 Miata, 1997-2002 626, 1997-2002 Millenia, 1997-2006 MPV and 2001-2006 Tribute.
