Frequently Asked Questions (FAQs)
1. Does the ECU control the fuel injectors?
Yes, the Engine Control Unit (ECU) is responsible for controlling the fuel injectors. It determines the injection timing and activates the injectors at the precise moment using inputs from sensors like the Crankshaft Position Sensor. This ensures that the fuel is injected into the engine at the correct time.
2. How does the ECU know how much fuel to inject?
The ECU uses a lambda sensor in the exhaust to determine the correct amount of fuel to inject. In closed loop mode, it adjusts the air/fuel ratio based on the feedback received from the lambda sensor, ensuring optimal combustion and fuel efficiency.
3. What causes ECU failure?
ECU failure can be caused by various factors, including short circuits in wiring or components. These short circuits may occur due to external influences or incorrect starting of the vehicle. Other causes can also contribute to ECU failure, but short circuits are a common one.
4. What happens when ECU fails?
When the ECU fails, it can lead to various issues with engine performance. These may include poor engine performance, stalling, misfiring, rough idling, decreased fuel economy, illuminated check engine light, or even a no-start condition.
5. Can ECU cause injector problems?
While fuel injector problems are not directly caused by the ECU, a faulty ECU can affect the proper functioning of fuel injectors. The ECU is responsible for controlling the combustion system, and if it malfunctions, it may not be able to provide the correct instructions to the fuel injectors, leading to issues with air/fuel mixture and combustion.
6. Do fuel injected cars need a tune-up?
Fuel-injected cars with electronic ignition systems typically do not require traditional tune-ups as frequently as older vehicles. However, regular maintenance is still necessary, with service intervals ranging from 25,000 to 100,000 miles, depending on the specific vehicle and manufacturer recommendations.
7. What sensor triggers the injectors?
The ECU uses sensors to determine the optimal timing for firing the injectors and spraying fuel into the combustion chamber. When the ECU activates the injector, pressurized fuel is sprayed into the combustion chamber through the nozzles.
8. How much HP does fuel injection add?
Fuel injectors can contribute to an increase in horsepower. Upgrading to new fuel injectors can provide a boost of up to 10 extra horsepower for a vehicle. However, the actual impact on horsepower may vary depending on the specific vehicle and its existing setup.
