Hyundai Genesis Coupe 2.0L G4KF MFI Control System Wiring Diagram SD313-5
Electrical wiring diagram of the MFI control system showing MAP sensors, fuel-tank pressure transducer, cruise and steering switch circuits.
This is page SD313-5 of the MFI (Multiport Fuel Injection) Control System wiring diagram for the Hyundai G4KF-GSL 2.0L turbo engine, page 5 of a multi-page set. It shows ECM (PHOTO 11) connections for numerous sensors and switches: ABS control module output (RR) and ESC control module CAN Low, MAP sensors #1 and #2 with pin numbers and wire colors, the fuel tank pressure sensor (FTPS), the A/C pressure transducer (APT), generator (FR) signal, vehicle speed sensor, and cooling fan LO/HI relay controls. The lower half covers the cruise control system (CCS): power from the CLUSTER/ESCL 7.5A fuse (SD313-4), through the clock spring and multifunction switch to the steering-wheel-mounted cruise remocon switch (CRUISE MAIN, CANCEL, SET/COAST, RESUME/ACCEL) with illumination, plus the A/CON switch, blower switch input, A/CON relay control, knock sensor with shielded ground/signal wires, ECM grounds to GHG01, power steering switch, and the cruise clutch pedal position switch (manual transmission). Wire colors (Br, G, B, O, Y/B, P/B, B/W, R, L, P, O/B, Gr), connector IDs (E03, E15, CHG25-1/2, F43, EF11, EC11, EC21, E02, M79, CHG23, CHG74, E07, GE06) and ECM pin numbers are given, with cross-references to related diagrams (SD253-1, SD941-2, SD971-3/9, SD961-3/5) and component photo numbers.

Frequently asked questions
- What ECM pins connect to MAP Sensor #1 on the G4KF 2.0L?
- MAP Sensor #1 (connector CHG25-1, PHOTO 15) connects via wires B, O, Y/B, and P/B to ECM pins 74 (Sensor Ground), 53 (IAT Sensor), 30 (MAP 1 Sensor Power), and 31 (MAP 1 Signal Input).
- Where does the cruise control system get its power?
- From the CLUSTER/ESCL 7.5A fuse, referenced from diagram SD313-4, feeding through wire R to the cruise remocon switch circuit on the steering wheel.
- What buttons are on the cruise remocon switch?
- CRUISE MAIN, CANCEL, SET/COAST, and RESUME/ACCEL, plus an illumination circuit (ILL.). It is shown at connector M79 with PHOTO 57, connected through the clock spring/multifunction switch (PHOTO 56).
- Which ECM pins are for the knock sensor?
- ECM pin 34 (Sensor Ground, wire B) and pin 12 (Sensor Signal, wire R) run in a shielded pair to the knock sensor at connector CHG23 (PHOTO 13), with the shield grounded at GHG01.
- How is the cruise clutch pedal position switch wired?
- On M/T vehicles, ECM pin 43 (CHG-A, Clutch Switch) runs via wire G through pin 16 of EC11 to the cruise clutch pedal position switch at connector E07 (PHOTO 55), which grounds via wire B to GE06 (PHOTO 44).
