1992 Geo Metro Throttle Switch Terminal ID (M/T) - Idle & WOT Switch Test

This document is page 2 of a Mitchell Repair Information (© 2005) service procedure excerpt for the 1992 Geo Metro, from the section 'I - System/Component Tests, 1992 Engine Performance, Geo System & Component Testing.' It contains a single illustration (figure reference 90H18009), captioned 'Fig. 3: Throttle Switch Terminal ID (Metro M/T),' courtesy of General Motors Corp. The diagram identifies the three terminals of the throttle switch on a manual-transmission Geo Metro: terminal "A," terminal "B," and terminal "C." A small schematic shows that the Wide Open (throttle) Switch is measured across terminals "C" and "B," while the Idle Switch is measured across terminals "B" and "A." The illustration also shows an ohmmeter connected with its positive and negative leads to the switch terminals, indicating that the throttle switch is tested by measuring resistance/continuity between these terminals. The page footer shows it was printed by 'Five Star Automotive Repair' on June 08, 2007. Readers can learn the terminal identification and ohmmeter hookup needed to test the idle switch and wide-open throttle switch on a 1992 Geo Metro with manual transmission. Note: although filed under a 2000 Ford E350 gallery, the document explicitly applies to the 1992 Geo Metro.
