Auxiliary Controls: Description

In addition to the regular exhaust emission control systems previously described, RX-7 models use several other "auxiliary" emission control devices. Some of these units may work in conjunction with systems previously explained, or they may have an independent function. These auxiliary controls include the control unit, idle switch (Man. Trans.), choke switch, full choke switch, acceleration sensor with delay valve (all Auto. Trans. and Calif. Man. Trans.), top switch and overdrive switch (Man. Trans.) or kickdown switch (Auto. Trans.), No. 1 water temperature switch and No. 2 water temperature switch (Federal only).
