Do Crankshaft Sensor Problems Affect Performance Of BMW X3 Vehicles In Marlborough?

Nowadays, all the modern cars including your BMW X3 come equipped with many sensors that keep a tab on the functioning of the vital parts of your car. One such sensor is the crankshaft position sensor which is responsible for measuring the position and rotation of the crankshaft of your BMW X3.

The moment the crankshaft position sensor malfunctions in your high-end car, the performance goes down drastically. Here in this article, we will discuss the problems faced by your BMW X3 when the crankshaft position sensor fails.

Engine Stalling & Backfiring

Whenever the crankshaft position sensor goes bad then you will find that engine behaves erratically and the first thing that you will experience while driving your car is related to stalling. The stalling in your car is caused due to inadequate fuel pressure in the engine.

Furthermore, the engine also needs proper air to fuel mixture for its efficient functioning and a drop in air pressure can lead to various issues including stalling and backfiring from your car. Now, whenever you encounter one of these problems suddenly in the middle of the road without any prior warning, then it indicates that something is wrong with the crankshaft position sensor.

The crankshaft position sensor is responsible for sending accurate data to the engine control unit (ECU) so that the fuel injection can be adjusted as per the need of the car. However, if there are discrepancies in the date sent to the ECU or if at all no data is sent then your car is going to stall suddenly.

Besides that, as there are many wires connecting the crankshaft position sensor to the ECU and if there is anything wrong with any of these wires or the wires are damaged then it can cause stalling & backfiring.

Fuel Efficiency Goes Down

Often it is noticed that people driving high-end car like BMW X3 don’t keep a tab on the fuel mileage of their car. Generally, they think that as they are driving a luxury car the mileage will be low. Well, the thinking is not completely true because even if you are driving a luxury car like BMW X3 then also you will have a fixed miles per gallon.

The important thing over here is that if you are keeping a tab on the fuel mileage of your vehicle then the moment you notice that it goes down drastically then there are some issues with the car. Due to the information sent by the crankshaft position sensor the fuel intake of the engine is adjusted accordingly.

However, when the sensor goes bad then the information sent by it is of no use to the fuel injectors and this is when the fuel mileage of your vehicle goes down. As the engine gets more fuel than what is required it reduces the fuel efficiency of your vehicle.

Misfiring Engine

One of the most dread problem encountered by any driver is related to the misfiring of the engine and this is a common problem associated with crankshaft position sensor. The fuel flow and the ignition timing of your vehicle needs to be in sync for the smooth running of the car.

The crankshaft position sensor monitors both the fuel flow and the ignition timing of your vehicle. In addition to that, the crankshaft position sensor also keeps a tab on the position of the piston and if there is any faulty information sent by the crankshaft to the ECU regarding the positioning of the piston, then you experience engine misfiring in your car.

Starting Issues

Often it is noticed that when the crankshaft sensor is faulty then you are going to face problems in starting your vehicle. The starting mechanism of your vehicle is very complex and the crankshaft sensor keeps a tab on the position and speed of the crankshaft & other parts that play a role in starting your car.

Now, if the crankshaft position sensor is on the verge of failing then you will see that your vehicle cranks but doesn’t start and if your sensor is completely lost then your care won’t start at all.

Finally

The above-discussed factors are some of the ways your BMW X3 gets affected due to a failing crankshaft position sensor in your high-end car. If you are encountering any of the issues then don’t hesitate to approach a certified mechanic for diagnosing and addressing your failing crankshaft position sensor.
