A camshaft sensor is one of the essential parts of your vehicle, so much so that you probably won’t be able to drive at all with a faulty one. Fortunately, the part is relatively inexpensive compared with a lot of other vehicle parts, and it only takes about an hour or so for a mechanic to replace it. However, that time can vary depending on the make and model of your vehicle. Luxury vehicles and those with more complicated engine systems are typically going to take a bit longer at the shop. In most cases, though, diagnosis takes longer than the actual replacement. Basically, if you already know that the camshaft sensor is the problem, the actual maintenance is fairly quick.

Replacing a camshaft sensor replacement yourself makes it easy to save money with a common DIY project. Without having to pay labor costs, you’ll be saving nearly half the expenses of camshaft sensor replacement services. Given that you only really need one part, it’s easy to find what you’re looking for and get it properly installed even if you don’t have prior experience. The steps are simple and easy to follow, and the equipment you’ll need is available in most households. The key is to know for sure that the camshaft sensor itself is the problem.
What Is a Camshaft Sensor?
The camshaft sensor tells the engine control unit where in its rotation the camshaft is located. This enables the computer to deliver the correct amount of fuel and air to each cylinder, as well as precisely when to ignite it.
What Does a Camshaft Sensor Replacement Include?
A camshaft sensor replacement typically entails just swapping out a broken camshaft sensor with a new one. Other systems don’t usually have to be replaced along with it. When you get this done at the shop, it should only take about an hour. Keep in mind, though, that this estimate assumes you already know what the problem is. If the shop has to diagnose one of the symptoms of a faulty camshaft sensor, the diagnosis could take longer than the replacement.
What Happens if You Don’t Replace the Camshaft Sensor?
Leaving in a failing camshaft sensor could trigger a wide variety of symptoms. Data from the camshaft sensor helps the engine computer controls some of the engine’s most fundamental operations. The less accurate the data, the more serious the problems. For instance, fuel efficiency or engine power may be reduced. The check engine light may be illuminated on your dash, which you can diagnose using the FIXD sensor and app. Eventually, it will get to the point where your car cannot start at all.
The P0340 code is a Camshaft Position Sensor Circuit Malfunction, and it warrants immediate attention and service. Its trigger is often a faulty camshaft sensor. It’s important to know just how serious this error can be. In addition to your car typically not being able to start at all, when it does start it will likely have reduced power in “limp mode.” This limits your acceleration and can compromise safety. Additionally, the increased fuel consumption that often accompanies this problem may cost more over time than the price of getting it fixed.
How Often Should You Replace the Camshaft Sensor?
Camshaft sensors are not considered a wear item and are not listed on the manufacturer’s recommended maintenance schedule. Still, they may fail and require replacement sometime during the life of your car. The engine’s heat can warp and damage electrical components over time, which includes camshaft sensors. While there is no specific time frame for replacing them, they are prone to failure late in a car’s life, past 100,000 miles.
These are general guidelines, and you should always see what your car’s manual recommends. Every make and model is different, and you should consider the specific maintenance schedule for your vehicle rather than following general guidelines. You can look up your specific make and model’s maintenance schedule using FIXD. The app even allows you to input your car’s mileage for a more specific schedule. Its automated alerts make sure you never forget when you need maintenance done.
