Park/Neutral Switch - A/T (Mode Switch) & Inhibitor Switch - M/T

NOTE: The vehicle should not be driven with the transmission range switch disconnected, as idle quality will be affected. Park/Neutral switch can also be referred to as Transmission Range Switch (TRS) or Mode switch.

Transmission Range Switch (TRS) provides one of four inputs to the PCM. Position is selected by transmission selector lever. This information is used for starting, ignition timing, EVAP canister purge or EGR operation.
