: Regulates emissions and boost pressure. Communication Lines :
Terminals for the Heated Oxygen Sensor (e.g., Pin 106) and MAP sensors, which provide the data necessary for the ECU to "see" how the engine is performing.
An Engine Control Unit operates strictly by marrying input sensors to output actuators. Pinouts are categorized into four logical zones: Pins dedicated to drawing clean
Unlike the later "standardized" Nissan ECUs (where pin 20 is always 12V and pin 23 is always ground),
: Technicians use a multimeter to "back-probe" the ECU harness. For example, battery voltage should typically read between 0.7V โ 0.9V or full battery voltage depending on the specific pin and state.
