What are the symptoms of a bad eccentric sensor?

More complex vehicles depend on sensor operations, including Eccentric sensors, which are responsible for monitoring rotation speeds, as well as help with the internal computer. When these do not work properly, they affect the cars’ performance, starting with the engine’s speed to fuel consumption, an integral element of the operating system, losing its functionality that generates failures.

Therefore, it is vitally important that you know in detail about the bad eccentric sensors, which will give you full knowledge of the system, and have the ability to fix it in case of failure. Learn more below.

What are the symptoms of a bad eccentric sensor?

When we focus on Eccentric sensors, this is an element of automotive performance that regulates engines’ ignition. If this fails, the engine’s efficiency is progressively lost, increasing fuel consumption, and in the worst cases, the vehicle is not started properly.

In this case, there are two types of eccentric sensors, the one already mentioned, and the crankshaft sensor. These have their own characteristics, but they comply with some general aspects, among them, we can mention:

  • Control of speed changes, increasing or decreasing certain parameters
  • Ignition timing control
  • Control of the time in which the injection is carried out
  • Time control in regards to motor advance

Thanks to the eccentric sensors, sequential injections are made, thus distributing the fuel found in each cylinder, just when the moment warrants it. In most cases, this type of sensor is closely related to a crankshaft sensor, since both allow the control unit to know the exact point where the engine is positioned.

The eccentric sensors inform the control unit of each intake and exhaust valve’s position. Thanks to this, the control units are responsible for injecting the fuel when the intake valves are open, and the piston is lowered, absorbing the mixture.

If timing changes are made and are not done properly, the eccentric sensors will indicate that something is not working properly. This sensor’s location is on the cam element, although on certain models, they are inside the engine. It is vitally important to have the workshop manual, which allows you to locate and examine the service.

Symptoms of the eccentric sensors that are in poor condition

  • Many elements show that the eccentric sensors are not working properly, so it is vitally important to recognize them and know how to identify them, ensuring that measures are taken according to the situation quickly and effectively. In this case, one such problem is lack of acceleration.
  • Considering the vehicle’s accelerator, if the eccentric sensors are not adjusted properly considering the speed, this feature will not rotate correctly, so the pistons that the sensor controls will be out of sync.
  • Fuel is to be supplied to the engines on an intermittent basis. This will cause the pistons to malfunction, causing the car to have problems with acceleration and maintaining speed. These problems, caused by the eccentric sensors, will get worse over time, causing the rest of the engine components to suffer.
  • The eccentric sensors are responsible for communicating the internal computer to the rotary position of the performance itself. When it does not work in the best way, the readings delay the spark plugs’ ignition with great risk. This action will cause fuel consumption and chaos to be affected in all scenarios since the engine loses synchrony in the interior’s combustion.
  • Another problem is unemployment or the inability to start. At low speeds, the eccentric sensors will cause the vehicle’s engine to stop completely. It may not turn on either, preventing the car from starting at some point.
  • It doesn’t happen regularly, as the car’s internal computer uses the latest readings from the eccentric sensors in piston actuation and fuel flow management. This will allow the vehicle to start but the driver will still experience other symptoms mentioned above.

Eccentric Sensors Process

In every car, the eccentric sensors have a magnetic field that is created with a magnet in which said element is located. These, too, inside have several pins, which are designed to rotate when the feature rotates.

The movement of the pins causes the magnetic field to fluctuate. The eccentric sensors are designed to detect magnetic movements in their fields, transmitting signals to the vehicle’s computer or electronic control unit.

In these cases, the computer uses these signals to determine the position and speed of the eccentric at a given moment. This is based on that information. The computer is in charge of deciding when to turn on the air-fuel mixtures and making the acceleration or deceleration adjustments appropriate in the circumstances.

The mechanism of the eccentric sensors focuses on using a toothed wheel that is attached to a said component, which with a Hall Effect, introduces current into the sensor at certain intervals or with an LED that turns on a light above the grooved wheels linked to the provision, with an element equipped with photoreceptors. This takes care of performing the mentioned actions, which are very important in the automotive experience.
