Which ECM terminals connect to the throttle position sensor?

ECM terminal B6 (Gr/R wire) goes to the sensor's Vc terminal, B7 (Gr wire) to Vs, A18 (Bl/W wire) to IDL, and B15 (Gr/Y wire) to GND.

What wire color is the TPS signal wire?

The Vs (signal) terminal connects to ECM pin B7 via a Gray (Gr) wire.

What color is the TPS ground wire and is it shared?

The ground is a Gray/Yellow (Gr/Y) wire to ECM pin B15, and the diagram shows a branch labeled 'to other sensors,' indicating the ground is shared.

Where are pins B6, B7, and B15 located on the ECM connector?

The document includes an ECM coupler pin-location view showing B7 and B6 on the upper row and B15 on the lower row of the left connector block.

What does the IDL terminal connect to?

The IDL terminal of the TP sensor connects to ECM terminal A18 through a Blue/White (Bl/W) wire.

This document is a wiring diagram for the Throttle Position (TP) sensor circuit, uploaded as part of a wiring reference set for a 1986 Suzuki Samurai. It shows the electrical connections between the ECM (Engine Control Module) and the TP sensor through an intermediate coupler. Four circuits are shown: ECM terminal B6 connects via a Gray/Red (Gr/R) wire to the sensor's Vc terminal (reference voltage), terminal B7 connects via a Gray (Gr) wire to the Vs terminal (signal), terminal A18 connects via a Blue/White (Bl/W) wire to the IDL terminal (idle switch), and terminal B15 connects via a Gray/Yellow (Gr/Y) wire to the sensor's GND terminal, with a branch noted as going 'to other sensors.' A numbered legend identifies the ECM, TP sensor, coupler, ECM coupler, and the shared ground branch. A second illustration shows the physical ECM connector (coupler) face, indicating where pins B6, B7, and B15 are located within the multi-pin connector blocks. A reader can use this diagram to identify the correct ECM pins and wire colors for diagnosing or testing the TP sensor circuit, including reference voltage, signal, idle contact, and ground paths.
