The Most Common Faulty Camshaft Position Sensor Symptoms
One of the electrical components in a car is the camshaft position sensor (CMP). We will discuss what this component is, how to know the faulty camshaft position sensor symptoms and how much it will cost to repair.
Because they sound similar, many people mistakenly believe that the crankshaft position sensor is the same as the camshaft position sensor. But since they serve different purposes in cars and exhibit different symptoms when something goes wrong with them, there are significant differences between the two. Here are the common camshaft position sensor symptoms
What Is A Camshaft Position Sensor?
The camshaft position sensor is a standard feature on all vehicles today. Any car needs this sensor as it helps to verify that the engine is working properly.
When looking under the hood, you may have trouble finding the sensor. Usually, each automaker will designate a certain location near the engine to place the sensor. It can be near the engine block, behind the cylinder head, or in the vehicle’s lift valley.
The job of the camshaft position sensor is to find out the position of the camshaft relative to the crankshaft. The powertrain control module (PCM) will use this information to control the fuel injectors and/or the ignition system.
The Most Common Faulty Camshaft Position Sensor Symptoms
Car Jerking or Surging
One of the faulty camshaft position sensor symptoms. Sometimes the engine can lose power and cause your vehicle to jerk or jump forward if the camshaft position sensor starts to fail while you’re driving.
Because the PCM is receiving incorrect data from the camshaft position sensor, both are due to the incorrect amount of fuel injected into the cylinder.
Engine stalling is a more dangerous but luckily less frequent symptom. You could experience this while parking or operating a vehicle on the road.
The latter scenario carries a great deal of risk. Avoid driving at all if your engine suddenly stalls.
This issue arises when neither fuel nor air enters the combustion chamber at the proper time, preventing combustion from happening.
Check Engine Light Illuminates
The appearance of a check engine light is one of the most typical signs of faulty camshaft position sensor symptoms.
As usual, it will be difficult to identify the problem until the light comes on. It is recommended to use an OBD2 scanner to check your vehicle for any trouble codes for a clearer picture.
You should bring your car in for repair if you don’t have an OBD2 scanner. If possible, avoid using the vehicle while the lights are on as this could lead to further damage.
Depending on whether a qualified mechanic or someone equally qualified has given you the go-ahead, you may be able to drive to the shop if you know the source of the check engine light.
The so-called “lime mode” can trigger frequently. This safety function limits the vehicle’s power and speed to protect all parts of the vehicle.
In general, if the lame mode is activated, you can drive to the nearest store. When you turn the engine on and off again, the lame mode may disappear, just like the check engine light.
Unable To Start The Car
One of the most common faulty camshaft position sensor symptoms is unable to start the car. Poorly functioning sensors will make it difficult to start the engine.
This can be due to a number of causes, like practically any other symptom. Other potential causes of a car not starting to include a bad starter, clogged fuel filter, dead battery, and other problems.
A locked transmission that only shifts into one gear is a problem with some car models that have a defective camshaft position sensor. You’ll have to turn off your engine, wait a little while, and then restart if you want to get out of that gear.
The problem will return because this is only a temporary cure, thus replacing the sensor is required for a long-term fix.
Your vehicle might also go into “limp mode,” which prohibits you from shifting gears or speeding up past a certain point.
The delivered signal to the vehicle’s computer decreases as a camshaft position sensor develops issues. This indicates that ultimately the signal will become so faint that it will prevent the car from starting because there won’t be an ignition spark.
This is one of the most common faulty camshaft position sensor symptoms. When everything is working properly, drivers usually won’t notice a pleasant, steady feeling of idleness. On the other hand, the raw idling state will be very obvious while driving.
Asynchronous combustion in the cylinder is what causes rough idling if the camshaft position sensor fails.
A poor fuel pump or EGR valve can also cause severe idling. It is important to understand what creates extreme idleness, whatever the cause. To find out, you may need a few additional tools and testing.
Bad Gas Mileage
An excessive amount of fuel can be introduced into the combustion chamber because the camshaft sensor gives incorrect information to the engine control unit.
In addition to pumping more gasoline, combustion will also take place at less-than-ideal intervals, resulting in more unburnt fuel and poorer gas mileage.
As this symptom develops over time, it can be more difficult to detect than other faulty camshaft position sensor symptoms. You should also pay attention to how often your vehicle uses fuel.
Reduced Engine Power
There are two types of motor power reduction. The vehicle is moving roughly and no notifications or dashboard lights are visible, or power is reduced as a result of limp mode, used as a safety measure.
When accelerating, you can detect less engine power or just reduce engine speed.
When accelerating, it can also manifest as vibrations. All these camshaft position sensor symptoms are caused by misbehaving engine cylinders and poor combustion.
If you notice any camshaft position sensor symptoms on your beloved vehicle, quickly take the car to the auto repair station for inspection to avoid problems when you use the car.
