Suzuki Samurai TP Sensor (TPS) Wiring Diagram - ECM Pins A18 & B15, Wire Colors

This document is a wiring diagram for the throttle position (TP) sensor circuit, uploaded as part of a 1986 Suzuki Samurai reference album. It shows the ECM (item 1) connecting through the ECM coupler (item 2) to the TP sensor coupler (item 4) and TP sensor (item 3). Four wires run between the ECM and TP sensor: Gr/R carrying Vin, Gr carrying Vout, Bl/W carrying IDL, and Gr/Y carrying GND. The diagram identifies ECM coupler pin A18 as the IDL (Bl/W) terminal and pin B15 as the ground (Gr/Y) terminal. Item 5 shows the idle switch built into the TP sensor on the IDL circuit, and an arrow (item 6) indicates that the ground wire also runs to other sensors. On the right, a drawing of the ECM coupler connector face shows the physical locations of pins A18 and B15 within the multi-pin connector. A reader can learn the wire colors, signal names, ECM pin assignments, and connector pin locations needed to test or troubleshoot the TP sensor and its integrated idle switch. The document itself contains no year, model, or part number information.
