The Need for Speed (Wheel Speed Sensor Maintenance)

Today's vehicles have some pretty amazing technology in them, including a computerized braking system we all pretty much take for granted these days.  Antilock brake systems (ABS) have been around for years but they help drivers stop in much shorter distances reliably than ever before.  When you see your ABS warning light come on, it's important to find out what's causing the problem. It's a safety issue.

Often the problem when the ABS light comes on is a faulty wheel speed sensor.  (In some cases the traction control light will also come on, perhaps because of a non-working wheel speed sensor.) Your vehicle uses the speed sensors to measure the rotational speed at each wheel. That sensor sends the speed data to a computer that can then adjust braking power and prevent your wheels from locking up. 

If any of the wheel speed sensors isn't working right, the ABS warning light will go on and the vehicle's computer will turn off the antilock brake system.  You'll still have working brakes, but you will lose the functionality of that computerized system.

When your vehicle warns you the ABS has a non-working sensor, you can have a technician check to see what's going on. It could be one of the sensors is dirty and a cleaning will solve the problem.  But it also could be that one or more sensors needs to be replaced. 

A technician will use computerized diagnostic equipment to determine what and where the problem is, replace any bad parts and then check to make sure the system is fully operational. 

Antilock brakes and traction control are significant technologies that help prevent your vehicle from slipping on less-than-perfect road surfaces, especially useful during wintery weather.  Make sure they're helping you drive the way they designed to.

Weather Station on Wheels (Vehicle Sensor Maintenance)

You probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool.

First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond.

Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient temperature sensor isn't working right, some symptoms are a malfunctioning automatic A/C or a temperature display that is way different than the app on your phone says it should be.

Your vehicle will also have sensors that measure your speed at each wheel.  They work with an onboard computer to measure slippage in any of the wheels so traction control and antilock brakes work correctly in case of slick roads.

Your vehicle can measure something called longitudinal and latitudinal acceleration, and it uses a yaw sensor to do it.  That helps it determine if you might be in an oversteering or understeering situation.  It's important because it works with your vehicle's brakes to apply stopping power to keep you in control.

A steering wheel sensor tells the vehicle's computers what the driver is doing with the wheel.  It also can work with those wheel sensors to measure how slippery the roads are, whether it be due to a wet (rain) or granular (gravel or sand) surface.  By sending different torque or braking to each wheel, it helps the driver maintain control.

More and more vehicles now have a rain sensor that can turn on the wipers automatically when they measure precipitation on the windshield.

So, you're driving your own weather station, and making sure all this data is coming in properly depends on how each component is working.  Regular service and maintenance on these systems is important to make sure they can do their job. Your rolling weather station can't predict the weather, but it can sure help you deal with it, so help it do its job right.

Give Your Engine Clean Fuel with a New Fuel Filter from Triple A Automotive

Your vehicle requires plenty of clean fuel to run. If your fuel contains contaminants, your fuel injectors will eventually become clogged up. When this happens, your vehicle engine may not get the proper amount of fuel at the correct pressure to run at peak performance. This hurts performance as you drive around the Clovis area. It can also lead to the buildup of harmful deposits on valves and in the combustion chamber.

That's why all vehicles, including vehicles, come equipped with a fuel filter. The job of the filter is to clean out little pieces of dirt and contamination. The filter captures the contaminants and keeps them out of the fuel stream. Of course, like all filters, it will eventually get clogged up and need to be replaced at Triple A Automotive in Clovis.

If your fuel filter is clogged, the vehicle engine can't get all the fuel it needs, and it may sputter at high speeds or quick acceleration. Many fuel filters have a bypass valve that will allow unfiltered fuel through when they are clogged. This keeps your vehicle engine running but doesn't protect it from  contaminated fuel.

Clovis drivers may find that they need to change their fuel filter at Triple A Automotive more frequently as their vehicle ages. Over the years, additional sediment and rust accumulates in the fuel tank and can be drawn into the fuel system. Your fuel filter stands guard at the gates to your engine to protect parts and to maintain performance.

Battery Replacement for Your vehicle

Modern vehicles in and around Clovis run on 12 volt electrical systems. 12 volts is enough to get the job done for Clovis drivers without having so much power that there is danger of electrocution. But today's vehicles have more electrical components and do-dads than ever before. This really strains your electrical system, making it hard for the battery to keep up. Think about it: electric seats, seat heaters, power locks windows and sun roofs. And then us CA drivers have all the power outlets for our cell phones, computers and DVD players.

We also have navigation systems and powerful stereos. Plus there are all the engine and transmission computers, traction control, stability control, anti-lock brakes, sensors and on and on. Even the security system is running off the battery while the car is turned off.

Fortunately, battery technology has given Clovis drivers resilient batteries that are able to meet these strenuous requirements. But the fact is, batteries just wear out over time. Eventually, every battery gets to the point where it cannot hold enough of a charge to start your vehicle. Sometimes batteries need to be replaced because they have just worn out. Or, in other cases, they have developed a leak which makes it even more important to get it replaced.

Special safety precautions are taken when working with batteries at Triple A Automotive in Clovis, CA. These precautions also apply to anyone who is poking around the battery. Batteries contain sulfuric acid that can damage your eyes and burn your skin, so safety glasses and rubber gloves are a must for any Clovis resident working with their battery. Be careful to not spill acid on your clothes or the vehicle's paint. Of course, avoid short circuiting the battery as well.

Sometimes there is quite a price range in Clovis auto part stores for batteries that will work in a particular car. Think of it as "good," "better" and "best." More expensive batteries have a longer warranty and are guaranteed to last longer. As with most things, paying a little more up front saves in the long run for Clovis drivers.
