RX7 2RTR-1308cc 1.3L MFI (1991)
Transmission Position Switch/Sensor: Description and Operation
Inhibitor Switch (A/T)
The Inhibitor Switch (sometimes referred to as neutral safety switch), located on the right side of the transmission, signals the EC-AT control unit as to
gear selector position and prevents starting the vehicle except in "P" or "N" ranges. The EC-AT control unit then signals the ECU whenever "P" or "N"
are selected. This input is factored into ECU calculations for outputs such as:
Fuel injection quantity
A/C relay/cut-off
EGR system control
AWS solenoid valve
Pressure regulator solenoid valve
BAC solenoid valve
6PI solenoid valve
Ignition timing control
