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.

Clean Slate (Protecting Vehicle's Finish)

Winter is one of the hardest times to keep your vehicle clean. But did you know neglecting to wash your vehicle in winter could cost you a significant amount of money in the long run? Here's why.

Many areas deal with snow and ice in the winter, and the salt and sand that are used to keep the road surfaces from being slick are also super corrosive to a vehicle's metal body and undercarriage.  That includes all the parts underneath that can be splashed with brine, saltwater and other road debris.  Winter is also tough on vehicles where there isn’t snow, sometimes from ocean salt or winter's extra humidity and rain. 

If you have any breaks in your vehicle's paint, whether it be from a little fender bender or a stone chip, that corrosive winter moisture can get through those cracks and start eating away at the metal underneath. 

If you can, you should get any dents or damage fixed as soon as possible so your vehicle has a protective layer of paint between road chemicals and the metal.  You may want to wait until the warmer weather, but while you're waiting, the damage is getting worse.  If you're not sure of a reputable body repair shop, check with the service advisor where you have mechanical work done.  They're usually knowledgeable about who is good and not so good. 

You also may be tempted to skip the car wash during the winter since your vehicle is just going to get dirty fast anyway.  You may want to reconsider.  Many winter road treatments now use brine that gets in every nook and cranny of your vehicle.  It's wise to clean that off regularly during the winter, and many washing facilities include a spray underneath that gets rid of that salt.  Your vehicle repair facility may even have its own car wash, a nice bonus when you take your vehicle in for repair or regular maintenance.

The Truth about Tire Pressure (Tire Inflation)

Most light vehicles (under 10,000 pounds/4,500 kg) in North America sold from 2008 model year on have a feature that many people are confused about.  It's the tire pressure monitoring system (TPMS).  You may have some experience with it yourself if you own a newer vehicle.  Vehicles with TPMS have sensors in each tire that are supposed to warn the driver when tire pressure gets dangerously low.  That's important because tires that are significantly under-inflated can cause very serious accidents.

Unfortunately, many drivers think the TPMS does all the work keeping track of tire pressure. To them, as long as the warning light or gauge isn’t giving a warning, the tires must have the proper amount of air pressure in them.  That's not the case.

Tire pressure monitoring systems aren't all created equal.   Some give you a digital readout of the pressures in each individual tire.  But many simply have a warning light that looks like the cross section of a tire with an exclamation point in the middle.  If you don't know what it is, it's because it's not instantly recognizable as a tire.  In fact, one company that makes TPMS, Schrader Performance Sensors, surveyed drivers.  Their study showed that more than 40 percent of drivers didn't know that that warning light was. 

One out of 5 of the drivers who did know what the light was only looked at their tires after the light came on to see if they could see any that needed air; they never checked them with a tire gauge or had someone else do it.  Ten percent of them didn't do anything when the light came on.

In most vehicles with TPMS, the warning comes on only when the tires are more than 25% underinflated.  The American Automobile Association says that's under the pressure you need for safe vehicle operation.

The bottom line is once a month you should make sure your tires are inflated to the manufacturer's recommendations.  That means each tire should be measured with an accurate, external tire gauge.  To be confident you are getting a correct reading, take your vehicle to a reputable service facility where their equipment is calibrated and they know what they're doing.

Severely underinflated tires can contribute to an accident that kills or severely injures people.  The idea behind TPMS is well intended, but the system was never meant to replace regular inflation measurements and maintenance.  Periodically have your tires checked for proper inflation.
