Volvo 240 Crank Position Sensor Symptoms

First off, let us talk about the crank position sensor. Now, your internal combustion engine needs rotational energy, which is delivered by the crankshaft. It converts any linear or reciprocating energy into a rotational energy that your vehicle needs to run.

The crankshaft position sensor detects the speed at which your crankshaft spins. When it is able to detect its spinning rate, this information is sent out to your engine control unit. Then, the latter regulates your ignition systems and fuel injection system’s timing. The timing must be right for your engine to generate the right amount of power to run. 

With all these things being said the crankshaft position provides your engine control unit every detail required. Various components are used by your crankshaft such as gearwheels, belt with teeth, and timing chain to drive your camshaft. Moreover, your engine relies on your camshaft to enable the exhaust valves to do their jobs at the right times.

When there is a problem with closing and opening the valves, this leads to issues with your exhaust system. This is why it is all connected to your crankshaft’s functionality. 

There are some symptoms linked with crankshaft position sensor problems such as the following:

1. Engine vibration

If you notice some vibrations from the engine, this means that your crank position sensor is acting up and causing your engine control unit to not manage your crankshaft correctly. This is why there is too much vibration going on, and you may even detect the vibration on your steering wheel.

2. Check engine light illuminates

When there are problems with any components in your vehicle, this can trigger the check engine light. This is why if your engine control unit is not getting the right information on the crankshaft’s position and speed, the check engine light may turn on. Additionally, your engine’s functionality may be affected. You may also see some trouble codes showing up such as P0336 and P0335. 

3. Reduced engine performance

Is your engine starting to stall, hesitate, or not start as efficiently as it used to? If so, then it could be because your crank position sensor is acting up. The engine control unit is unable to determine the correct position of your cylinders or crankshaft. Therefore, there is a delay in your ECU’s ability to maintain the engine’s optimal performance and operation.

You may notice engine hesitation whenever you step on your gas pedal harder. It may even fail to respond, which can be quite dangerous when you do this on the road that needs you to perform more quickly without any hesitation.

4. Starting problems

Are you experiencing some difficulties with starting your vehicle? In this case, it is possible that you have a crank position sensor issue. This means that your engine control unit is not getting the information required to start the car. You may also eventually develop long-term problems with starting the engine completely, which can be a major inconvenience.

Stalling engine issues can also arise over time. This is why it is good to have the sensor replaced sooner than later, so you can have this problem resolved once and for all. 

5. Cylinder misfire

If you have a faulty crankshaft position sensor, it is unable to send data on the piston position to your engine control unit. Therefore, some misfires may arise in your chamber cylinders. There may also be a possibility of a bad spark plug, but it is never ideal to just rule out a potential crank position sensor problem.

Further Points To Consider

With all these things in mind, you may be wondering what steps you need to take. If you experience any of the symptoms we have mentioned above, then it is absolutely possible that your crank position sensor is at fault. So, the next step is to have a licensed mechanic take a look at this part and have it fixed sooner than later.

Generally, the cost of getting a crank position sensor replaced can go from $120 to as much as $300. This would mean that you need to first buy the part which can vary from $75 to about $120, depending on the extent of the problem. As for the labor cost, expect to pay about $45 up to $180, and the price depends on the mechanic and where you are getting it done.

Bottom Line

Overall, there are many Volvo 240 crank position sensor symptoms to keep in mind, which you need to check if you are experiencing constant problems with your engine. We highly recommend that you get these issues addressed sooner than later considering how it can impact other parts. Moreover, the last thing you want is to eventually have to replace your engine, which is a very expensive thing to do and a huge inconvenience over all.
