15 SIGNS OF A BAD ECU (ENGINE CONTROL UNIT)
#enginecontrolunit
In this video i will tell the 15 symptoms of a bad ECU Engine control unit and explain them.
An ECU’s main job is to keep the engine working smoothly. On cars fitted with electronic fuel injection, an ECU can control the amount of fuel that enters the engine’s cylinders.
This optimises the fuel-air mix in the cylinder when it’s compressed, which in turn maximises the car’s power and reduces the amount of fuel wasted

    Are you talking about when the car is moving or at iddle as my car is not reving past 3000 RPM and the speed is going to limp mode at 100mph. But at idle if i rev it the RPM goes past 3000 RPM to the end. What is the problem?😊

    • @topuniversaltech1482
      @topuniversaltech1482 5 місяців тому

      Well Many modern cars have a built-in rev limiter that prevents the engine from exceeding a certain RPM while in neutral or park to protect the engine. But it can occur even in idle in erlier cars, as for you car I would say that you should plug in the OBD 2 scanner to check for the cause of the problem, to be more precise

      Hello! Well Common causes may include: 1 Faulty sensors (such as the throttle position sensor or mass airflow sensor 2 Clogged fuel injectors or a failing fuel pump. 3 Ignition system problems (spark plugs, ignition coils). 4 Transmission issues, including low fluid levels or a malfunctioning transmission control module. Cant tell exacly what part to change without doing a proper diagnostic! Please consult a professional mechanic nearby to perform a thorough diagnostic to address this issue properly
