Engine speed/crankshaft position sensor (Negative/Ground). Pin 15 (P): Ignition pulse/primary ignition control.
While specific pin locations can vary by year and exact model (e.g., S200V vs. S210P), many Daihatsu EF-series ECUs share standard terminal labels found inside the casing or in factory service manuals. +B1 / +B2: Main power supply from the battery/ignition. E1 / E2: Main ECU grounds. PIM: Pressure Intake Manifold (MAP sensor signal). THW: Water temperature sensor signal. THA: Intake air temperature sensor signal. OX: Oxygen (O2) sensor signal. IDL: Idle switch signal. SPD: Vehicle speed sensor signal. N+ / N-: Engine speed (RPM) or crankshaft position signals. VC: 5V reference voltage for sensors. Pro-Tips for Pinout Troubleshooting daihatsu hijet efse ecu pinout hot
If you need help with a specific wiring issue, let me know the of your Hijet, or whether you are running into specific diagnostic trouble codes (DTCs) . I can provide the exact diagnostic steps to pinpoint the problem. Share public link

The Electronic Control Unit (ECU) manages the Electronic Fuel Injection (EFI) system by processing signals from various sensors and controlling actuators like injectors and the fuel pump. In many Hijet models, the ECU is located behind the dashboard or glove compartment area. Critical ECU Pinout Terminals
The equipped with the EF-SE engine uses a specific Engine Control Unit (ECU) pinout configuration common in various S200-series mini trucks and vans manufactured between 1999 and 2009 . These systems typically feature a multi-plug connector setup—often a 22-pin or similar multi-row configuration—to manage fuel injection, ignition, and sensor feedback. Core EF-Series ECU Pin Functions S210P), many Daihatsu EF-series ECUs share standard terminal
Example: "W-R" means a White wire with a Red stripe.
Looking directly into the wire-entry side of the plug (or the back of the PCB sockets), the pinouts for the are categorized to ensure the engine runs flawlessly. Sensor and Input Pins
