In the rest of this post, we will let you know the best way to remove the crank position sensor wire. This is an easy task that can be completed without the need to visit a trusted mechanic within the neighborhood. You might be intimidated at first if you are not experienced in DIY tasks. However, once you read this post, you will realize this is an easy task.
The crank position sensor is mounted in a bracket. There is a small nut, which serves as the connection between the bracket and the plate. It is difficult to access the nut because of the parts that surround it. There are two ways to remove the crank position sensor wire.
The first one is more difficult as some pulleys and accessories are still installed on the front. The second one will remove these accessories so that you can access what you need to remove easier.
The crank position sensor wire provides the connection to link two parts together. When the wire has been damaged the performance of your engine can be compromised. This makes it important to inspect it regularly and determine if it needs a replacement. When the latter is the case, the discussions in the rest of this post can prove to be handy.
Things You Need to Follow this Tutorial
The materials needed to complete this task are very much basic. You won’t need a lot, and chances are, the tools are already available in your garage.
- 8-millimeter socket
- Extension bar
Step-by-Step Guide on How to Change Crank Position Sensor Wire
Now that you have the necessary materials, this section will tackle the specific instructions involved. In this case, the instructions will be divided into two parts. The first one is quite more difficult as some pulleys and accessories are still installed on the front. The second one will remove these accessories so that you can access what you need to remove easier.
First, watch the short video below so that you can see how it is actually done, which will make the entire job a whole lot easier.
Without Removing the Pulleys and Accessories
The crank position sensor is mounted in a bracket. There is a small nut, which serves as the connection between the bracket and the plate. It is difficult to access the nut because of the parts that surround it. This will limit your movement. The wrench won’t be able to fit, and your movement will be limited.
- You will need a long extension with a length of at least 12 inches, which should have a quarter-inch drive universal joint.
- Try to move the joint. If it is wobbly, it is best to wrap it with electrical tape to keep it more stable.
- Connect an 8-millimeter socket at the end of the universal joint.
- Position the socket on the end of the nut underneath the vacuum pump.
- Bend the extension. Place the ratchet on the other end of the extension and turn it around. The nut will already be loose at this point, and you can unplug the crank position sensor wire.
Removing the Pulleys and Accessories
This is going to be an easier task. Once you have removed the pulleys and the accessories, you will have unobstructed access to the nut, which will make its removal a snap.
- Start by removing the pulleys and the vacuum pump. You can now have a more detailed view of the nut, and it will be easier to figure out how it can be removed.
- Use an 8-millimeter socket to remove the nut. Rotate the wrench until the nut is loosened.
- Once the nut is loose, you can turn it around by hand. Remove the wire, and at this point, you are already done.
Knowing the steps in removing the crank position wire is important, but it would be better if you also keep in mind the things that will be mentioned in this section.
When To Replace a Crank Position Sensor Wire?
One of the first things you must be familiar with is when a replacement is warranted. This is not simple guesswork. You need to pay attention to the symptoms that this component is already failing. That being said, here are some of the signs that you should be watching out for.
- The wiring and the connectors can be deformed. Pay attention to its physical appearance. The wire can already be stripped, and the connectors can be corroded or rusted.
- If your tachometer is not working properly, this could be a sign that the crank position sensor wire needs to be replaced. However, this is only one of the many reasons. A proper diagnosis is required to ensure the problem with the wire is true.
- A misfiring and stalling engine can also be an indication that there is a problem with the crankshaft position sensor and wire, although it can also be caused by a number of other factors.
Choosing a New Crank Position Sensor
When you are looking for a replacement for the crank position sensor that will be removed, here are some of the most important factors you must consider.
- Be aware of the different types that are available. Choose one that is suitable for the vehicle that you have.
- There should be high-heat resistance, and it must be made of durable materials, especially wire. This will provide an assurance that it won’t ask for a replacement for a long time.
- It will be good if the kit is already inclusive of O-rings.
Installation of New Crank Position Sensor Wire
Once it is removed, the next step is to install a new one. This can be accomplished by following these simple steps:
- Install the new crank position sensor in the same place where you have removed the old one. You will need an O-ring or a mechanical gasket to ensure it stays in its position.
- Once the sensor is in place, connect the wire. Install the nut and the bolt based on the torque that has been specified.
- Connect the other end of the wire. See to it that the sensor is engaged with the use of the connector clip that is provided. If not, it will be prone to be unplugged while the engine is running.
- Reconnect your battery, lower the car, and you are now ready to run the vehicle. Pay attention to the dashboard and make sure there is no warning indicative of a problem.
At this point, I hope you already know how to change the crank position sensor wire without asking the pros for assistance. As noted, it will be easier if you remove the pulleys and the accessories first. Nonetheless, even without doing so, you can remove the wire by using an extension wire and the right-sized socket.
