Engine Management Repair
Whether your car is not beginning, has an intermittent problem or a warning engine light has actually come on, we can help. Our technicians can inspect your entire engine management system utilizing a Scan Tool filled with data on the most recent designs to read fault codes and live data. These are carried in a great portion of the vans. Please mention you have this type of problem at the time of booking to guarantee we can send out the suitable van and mechanic.
All components can be checked such as ECU, Crank Angle Sensor, Cam Angle Sensor, Throttle Position Sensor, Air Flow Meter, Oxygen Sensor, Coil Pack, Ignition Module, BCM Module, DFI Module Air Temperature Sensor, Coolant Temperature Sensor, and Injectors.
The check engine light which is typically found in the instrument cluster is the engine management system’s warning light and is lit up if the ECU signs up a fault has actually taken place in the engine management system. If a fault occurs the ECU will record the fault code and this can be downloaded to assist in detecting faults with your vehicle.
Common Engine light on issues include:
Oxygen sensing unit fault (can be caused by bad quality fuel).
Catalytic convertor failure.
Emissions system fault.
The engine management system includes numerous parts that are kept track of by the electronic control unit (ECU). The ECU is a computer which analyzes electrical signals received from various sensing units and determines the correct fuel/air mixture to deliver to the engine so that it can react to various owning circumstances.
As the engine needs different amounts of fuel to suit various operating temperatures (ie: cold engines need more fuel) the ECU requires to establish the engine temperature level and does this by means of the coolant temperature level sensing unit. Ambient air temperature level also plays a function and an air temperature sensing unit sends a signal to the ECU to help identify the need for richer or leaner fuel mixtures.
The ECU signals the fuel pump to run when the ignition secret is relied on the start position and the throttle position sensing unit assists the ECU determine whether the engine is idling, accelerating or at complete throttle and the ECU adjusts the fuel mix to suit. Fuel is delivered under pressure to the top of the fuel injector which delivers fuel in a fine spray into the induction system. The crank angle sensing unit gives the ECU an indication of engine speed and piston position to assist the ECU determine injection timing.
Engine management systems also include the ignition system by managing trigger timing which leads to optimised efficiency and emission levels. Many modern-day automobiles have a direct ignition system which utilizes an ignition coil for each cylinder. The ECU fires the coil at the correct time utilizing recommendations from numerous sensors.
