Which ECM pin carries the TPS 1 signal?

ECM connector CHG-K pin 80 carries the TPS 1 Signal, connected to ETC module terminal 4.

Which pins control the ETC throttle motor?

ECM pin 71 is ETC Motor [+] Control (ETC module terminal 3) and ECM pin 72 is ETC Motor [-] Control (ETC module terminal 6).

Where are sensor power and ground for the ETC module?

Sensor Power (+5V) is at ECM pin 63 (ETC terminal 2) and Sensor Ground is at ECM pin 59 (ETC terminal 1).

What connector does the ETC module use?

The ETC module uses connector CHG65, a 6-pin harness connector with pins arranged 3-2-1 over 6-5-4.

How many pins does the ECM connector CHG-K have?

The CHG-K ECM connector diagram shows a 94-pin layout in four rows of 22 pins plus six side pins (1-6).

This document is a factory-style circuit diagram for the Electronic Throttle Control (ETC) system, showing how the ETC module (connector CHG65) connects to the Engine Control Module (ECM, connector CHG-K). The circuit diagram traces six wires between the throttle body and the ECM: Sensor Power (+5V) at ECM pin 63, TPS 1 Signal at pin 80, Sensor Ground at pin 59, TPS 2 Signal at pin 82, ETC Motor [+] Control at pin 71, and ETC Motor [-] Control at pin 72. A Connection Information table lists each of the six ETC module terminals with its corresponding ECM pin and function. The Harness Connector section illustrates the 6-pin CHG65 ETC module connector (pin arrangement 3-2-1 over 6-5-4) and the large 94-pin CHG-K ECM connector, with a full pin-numbering map and the relevant pins highlighted. A reader can use this page to identify pin locations for diagnostics such as testing TPS 1/TPS 2 signals, sensor power/ground, and throttle motor control circuits. The upload attributes it to a 2010 Hyundai Genesis Coupe 2.0L; the document itself shows no year or model markings.
