🔌 Function

  

The ECU is the main engine-management module. It receives signals from the crank, throttle, temperature, knock, MAP, oil-pressure and other engine sensors, then controls fuel injection, ignition timing, idle strategy, guardian functions and diagnostic fault storage.

  

Common signs of failure:

  

• No-start condition with correct fuel pressure and ignition inputs

• No communication with diagnostic equipment

• Intermittent stalling or loss of injector pulse

• Engine running excessively rich or lean despite correct sensor inputs

• Fault codes that return after wiring, sensor and power-supply checks

• Ignition or fuel-control faults isolated to the ECU after testing

• Poor idle quality or limp-mode operation caused by internal module failure

  

📦 Condition

  

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
