Effects of Worn-out Engine Harness Wires on Your Lexus

by schearerswpadmin September 2, 2020

With a car as notoriously reliable as Lexus, you should not have to worry about replacing parts too often. Every once in a while, however, some parts wear down. One of the more important ones to keep an eye on is the engine harness wires.

Your engine is a powerful piece of machinery and requires a lot of support to function properly. Ensuring that support structure remains in place is imperative to the performance of your vehicle. Worn out engine harness wires can be a serious issue if left unchecked and should be handled by a professional.

What do the engine harness wires do?

Contrary to the name, this is not a literal harness under the hood of your car. In a way, it looks like a harness, but it is really made up of a large number of electronic wires. These connectors and terminals extend out like tentacles under the hood and connect to important components such as the alternator and fuel injectors.

Whenever your engine is running, signals are being sent through this harness to the other parts of your car and making sure they activate when and how they should. This is done via electricity.

The battery in your Lexus is powerful and it is the lifeline of the car. As a current travels into the engine harness wires, it passes through a fuse box which ensures the current is not too strong. From there, it enters into the engine and can disperse to the surrounding parts.

These wires are like blood vessels under the hood of your car. It also helps to think of this structure as the never center. Should this system go down or be worn out too much, your car may likely become undrivable.

Signs of Worn Out Engine Harness Wires

Fortunately, it is quite easy to notice something is wrong when the engine harness fails. Wrong voltages of electricity or a lack of electricity often result in noticeable problems that will likely send your mind racing. Any of the below problems should be seen as serious. You should bring your car into a trusted shop right away.

Unexpected Engine Rev

If the engine is picking up on the wrong signals, it may receive too much or too little power. When this happens, you may notice that the vehicle begins to rev up or down at random times when it shouldn’t. This is due to the inaccurate transfer of electricity among the engine harness. This can be potentially dangerous.

Engine Shutting Off at Low Speeds

When the engine harness is not working properly, it is possible you will not receive adequate power when you slow the car down. The engine may stall on you. If this happens, you should pull your car off the road right away and call for a tow to your nearest shop.

Issues Starting the Car

As you may have guessed, starting the car could prove difficult if the engine harness is worn down. You could have battery problems, but if you test the battery and see it is juiced, the problem may lie with the current not being transferred through the engine harness wires.

Electronic Issues

Mentioned earlier, the harness wires are akin to the nerve center of your car. If the signal is cut off to certain parts, you may observe weird electrical occurrences and faulty electronics. This may even make its way to the dashboard of your Lexus.
