The camshaft position sensor and crankshaft position sensor work together to signal the accurate location of the crankshaft drive. It is a delicate and important process that helps the engine control unit.
Today, we are going to discuss whether camshaft and crankshaft sensors can cause a misfire.
Can camshaft sensor cause misfire?
A camshaft sensor that has gone bad can certainly cause a misfire in the car engine. A bad camshaft sensor can create multiple problems in the car including increased fuel consumption, reduced engine performance, and failure of the engine control unit to inject fuel into the engine accurately.

The primary job of the camshaft position sensor is to detect the rotation of the camshaft. The location of the camshaft position sensor is at the head of the cylinder. The timing rotor is located opposite to the camshaft sensor and on the engine camshaft.
The engine control unit coordinates with the camshaft position sensor to complete cylinder recognition.
Knowing the accurate position of the crankshaft drive helps to determine the ignition and injection point. The Hall principle is followed by the camshaft position sensor.
By following the Hall principle, the change in voltage is sent to the engine control unit in order to calculate the required data.
Sometimes the camshaft sensor can go bad for several reasons. When it goes bad, it fails to perform its important duties. Your camshaft position sensor can go bad if it has multiple patches of loose wires or any other toxic chemical waste on it.
The camshaft position can go bad because of a faulty crankshaft too. Because they work together in tantrums.
The camshaft sensor can also go bad because of overheating issues. Whatever may be the reason behind a bad camshaft position sensor, it can certainly cause a misfire in your engine. When you detect the camshaft sensor becoming bad, you should replace it immediately.
What are the symptoms of a bad camshaft position sensor?
A bad camshaft position sensor will start showing several symptoms. Let’s discuss them in detail.
Increases fuel consumption:
A bad camshaft sensor will send false data to the engine control unit. Because of receiving inaccurate data, the engine control unit will fail to regulate the fuel consumption of the engine. It will increase the fuel consumption of your engine drastically.
Reduces the performance:
A bad camshaft sensor will reduce the overall performance of the car. Your car engine will start idling or stalling. You will also notice a significant drop in the performance of your car engine.
Turns on the check engine light:
A bad camshaft position sensor can cause the check engine light to turn on. Although the check engine light can come on for many reasons, it is wise to run the error code of the camshaft sensor to find out if it has gone bad.
Causes starting problem:
You will fail to start your car if the camshaft position sensor goes bad. The signal sent by the camshaft sensor becomes weaker if it becomes faulty. As a result, you will face problems while starting your car.
Makes transmission shift difficult:
A bad camshaft sensor can make transmission shifting difficult because it sends inaccurate data to the engine control unit.
Is it safe to drive with a bad camshaft sensor?
A camshaft sensor can become bad for several reasons. It is considered safe to drive with a bad camshaft sensor. But it is not wise to do so.
Because if you keep driving with a bad camshaft sensor, it will eventually increase the maintenance cost of your car by causing all sorts of problems.
If you sense a problem in the camshaft sensor of your car, it is better to get it checked by a mechanic. Because a bad camshaft sensor will reduce the performance of your engine and affect the other parts of your car.
If you keep driving with a bad camshaft sensor, your engine will stop performing at the optimum level.
How much does it cost to replace a camshaft sensor?
Replacing a camshaft sensor does not cost you as much as replacing other parts of your car. The parts needed for the replacement will cost you somewhere between fifty to one hundred USD.
The labor cost for replacing the camshaft position sensor can cost you about eighty to one hundred dollars. This brings the total camshaft sensor replacement cost to one hundred and fifty to two hundred USD.
Can crankshaft sensor cause misfire?
A crankshaft sensor that has become faulty can cause a misfire in the car engine. The engine control unit fails to inject fuel efficiently into the engine if the crankshaft position sensor becomes faulty. Because it sends inaccurate data about the speed and position of the crankshaft.
The crankshaft position sensor’s primary function is to evaluate the speed and position of the crankshaft. The evaluation is then sent to the engine control unit for further action. The camshaft position sensor can be found beside the flywheel ring gear.
The data is sent in the form of an electrical signal. The engine control unit utilizes the signals to detect the position and speed of the crankshaft. The gained data is then used to determine the ignition and injection timing.
A crankshaft position sensor can go bad if your car has faulty internal wiring. A damaged timing belt can also cause the crankshaft sensor to go bad. An overly heated engine can also cause permanent damage to your crankshaft sensor.
A bad crankshaft sensor will fail to send accurate data about the position and speed of the crankshaft to the engine control unit. As a result, the engine control unit will fail to control the flow of fuel into the engine and it will cause a misfire in the engine cylinder.
A bad crankshaft position sensor needs to be immediately replaced or replaced in order to protect the engine from permanent damage.
What problems can a bad crankshaft sensor cause?
A bad crankshaft position sensor can cause several problems. Let’s discuss them in detail.
Starting problem:
A crankshaft position sensor is responsible for regulating the speed and position of the crankshaft. This plays a significant role while starting the engine. If you have a bad crankshaft sensor, you will have difficulty starting your car.
Acceleration problem:
A bad crankshaft sensor will fail to deliver accurate data to the engine control unit about the speed and the position of the crankshaft. As a result, your car will fail to accelerate with accuracy.
Engine problem:
The performance of the engine will be the most affected by a bad crankshaft position sensor. Your engine will start rough idling or stalling if your crankshaft sensor goes bad. It even causes a misfire in the engine of your car.
Gas mileage problem:
A faulty crankshaft position sensor will not be able to send exact timing information to the engine control unit. Because of this, the fuel injectors will be unable to perform their function accurately and reduce the gas mileage of the engine.
Check engine light problem:
A bad crankshaft sensor will cause the check engine light to come on. The check engine light can turn on for many reasons. It is necessary to use an error code to find out if the crankshaft sensor has gone really bad and replace it immediately.
Otherwise, the check engine light will not stop coming on.
Is it safe to drive with a bad crankshaft sensor?
Many things can be responsible for a bad crankshaft position sensor. It is wise to repair or replace the crankshaft sensor when it goes bad. Because it is one of the most important sensors of your car.
Without knowing the exact position and speed of the crankshaft, the engine control unit will not be able to maintain the injection of fuel into the engine. This will cause the engine acceleration and starting problem. Your engine will even start stalling.
These are not good signs for the health of your car if you want it to give good performance. Thus, it is not safe to drive with a bad crankshaft sensor.
How much does it cost to replace a crankshaft sensor?
The replacement cost of a crankshaft sensor depends on the model of your car. But generally, one hundred to one hundred and twenty USD is required for the parts of a crankshaft sensor.
The labor cost of replacing the crankshaft sensor can be one hundred to one hundred and fifty USD. So the total cost of replacement is about two hundred to two hundred and fifty USD.
Final Thoughts
Camshaft and crankshaft sensors can cause misfires in the engine if they become faulty. The camshaft position sensor and crankshaft position sensor are responsible for coordinating accurate fuel injection into the engine. If these sensors go bad, the overall performance of the car will reduce.
