As you know, today’s vehicles rely on a lot of computers in them to keep them running clean and efficiently.  Those computers depend on information delivered by several sensors throughout the engine and exhaust system.  And one of the most important is the oxygen sensor.   Known as the O2 sensor for short, it looks for too much unburned oxygen that has made it into the exhaust. That signals something isn’t right with the engine’s air-fuel mixture.  The sensor sends signals to the engine’s computers, which can then make adjustments to make sure the engine is running as it was designed to. Some vehicles can have several O2 sensors, and since they can measure oxygen at various points in the combustion/exhaust process, the computers can pinpoint where the problems lie.  For example, an O2 sensor can detect how much oxygen is coming out of the engine’s combustion chamber, and another one can measure oxygen coming out of the catalytic co ... read more

When it comes to ease and precision of steering, today’s vehicles are engineering marvels.  One of the keys to just how good steering is lies in the refinement of power-assisted steering which we know simply as power steering.  At the heart of the system is an electrically or belt-driven power steering pump.  It can apply hundreds of pounds of hydraulic pressure to the steering gear so you can turn your heavy vehicle with little effort. The more time and distance your vehicle travels, the more wear your power steering pump experiences. One sign your pump may be aging is that you hear a whining or groaning sound coming from your wheels when you turn. You also may feel a vibration through the steering wheel, or the wheel is harder to turn or responding more slowly than normal.  Another sign of trouble with the power steering pump is power steering fluid (reddish-brown) leaks on the ground around your vehicle. If you encounter these symptoms, have us check your v ... read more

It's a light many drivers fear they'll see turn on at the most inopportune time.  It's the one on the dash that says "Check Engine," "Service Engine Soon," or it may be simply an engine-shaped light. Your first instinct may be to pull off to the side of the road and turn off the engine. The truth is that Check Engine light can be pointing to problems as simple as a loose gas cap. But it could be as serious as a severely misfiring engine.  Don't ignore it because it's there to help you avoid an expensive repair it is designed to alert you to, to tell you something's not quite right. Your vehicle has a connected system of computers and sensors constantly checking to see that all systems are working the way they should. If something isn't, the system will turn on the Check Engine light. If it's flashing, that could be serious. Look at some of the other warning lights or gauges such as heat or oil pressure. They could be telling you your vehicle's problem should be checked right ... read more
