Modern cars have rapidly graduated from the old style engines that had carburetors to better designs that use computerized systems to perform a host of actions. Every car that you will come across on the roads today has a specific communication box called the ECU (engine control unit) with the ECU in place, there are lots of functions that are co-ordinated from this unit and for this to happen, there are many sensors linked to the ECU that are positioned in different places within the car. Bad crankshaft position sensor symptoms are simply the things that happen to your car as a result of failure or poor positioning of the crankshaft sensor.
There are many things that can happen in your car that should give you warning to the fact that you have a bad crankshaft position sensor. In most vehicles, the first sign that you will notice is the check engine light. This is a blinking red light that is right on the dash board. This light is positioned on the dashboard because the driver should never miss this light. Once the light comes on, the driver should take charge and make sure the vehicle gets checked before it completely stalls.
Main crankshaft position sensor symptom
Main sign that can make a driver know that the car has a bad crankshaft sensor position is the occasional stalling of the car. With the break in the chain of communication to the ECU, there will be a host of problems with fuel injection and this occasionally may lead to the vehicle coming to a stop. The sudden stop is often as a result of lack of proper running of the engine.
In other vehicles, you might easily notice when the crankshaft sensor is wrongly positioned and have a crankshaft position sensor symptoms if the engine rumbles or vibrates so loudly you cannot afford to ignore it. It is important to make sure you pay attention to the engine as you drive so that you can take note of any changes in the smooth running of your vehicle. There are also instances when the sensor may completely fail or just drop off altogether. The same effect will happen and a diagnostic check using the right diagnostic tools can easily point out where the problem is.
Generally, a vehicle will experience general engine Mal-function as a result of the sensor failure or even its poor positioning. When you have such problems, you can either have the sensor removed and cleaned before proper positioning to make sure you get the most accurate results.
