So your vehicle won't start. What's the first thing that comes to mind? Battery dead? Starter motor worn out? Out of gas? Well, those are all reasons that make sense. But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it. Here's how that works. You have lots of computers in your vehicle. They need to know the status of things so there are several sensors monitoring various things going on. These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel. They know when things aren't quite right and prevent you from starting your engine if that's going to damage it. Other sensors make sure the coolant is the right temperature, check to see you are not polluting the air and make sure other electronic components are performing their tasks correctly. Here's an example of a sensor doing its job. Your engine needs oil to lubric ... read more

Would you buy a jacket without even trying it on? Probably not, but it might surprise you that one study shows about half the people buy a vehicle after a short test drive around the block or none at all. If you're in the market for another vehicle, make sure you check out the most important things so you'll know if that's the right vehicle for you. Check out the gadgets. Love a good sound system? Then turn it up loud. Does it have enough bass for you? See how you like its navigation system if it has one. Try pairing your Bluetooth smartphone with the vehicle. Test out how to set the cruise control and how steady it keeps the speed. Back up and check out the rearview camera. If you buy this vehicle, you'll have to live with all of these things every time you drive. Test the vehicle on roads you know. See how it handles bumps and potholes, how it takes that tight curve that you drive every day to and from work. Driving on familiar roads gives yo ... read more

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 s ... read more
