Weather Station on Wheels (Vehicle Sensor Maintenance)

Posted March 17, 2024 8:09 AM

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.

This was my first experience with Long Hill Auto Body and I can confidently say it's a gem!! Without ever meeting me, Bob (owner) went out of his way to help fix a problem with my daughter's car and was so generous with his time and the advice he offered (problem solved). You can see this business runs like a well-oiled machine and Bob is the heart behind it, a genuine and caring owner who puts customers first. For my family, there's no question...we've found our trusted auto shop. Thanks again Bob and everyone at Long Hill Auto Body!

I called to have a photo inspection for my car and I called and the person answering phone was polite and told me when to come over. When I got there I was greeted and helped right away. They did my inspection quickly and I was on my way. Very pleasant gentlemen working there!

A few weeks back my wife was driving from PA to NYC by herself and started to have some car trouble. She called me from route 78 and I advised her to get off at the next exit and head to the closest repair shop. Thankfully it was Longhill Auto. At the end of their business day they got right on checking the car out, and were gracious with my wife who was having a very stressful experience. They were in touch with me every step of the way. Ultimately performed the necessary repairs and thoroughly test drove the car to give us peace of mind it was in good shape before making the hour plus drive out to pick it up. Would definitely recommend them and even going out of your way to work with them as it isn’t always easy to find a good shop with great people.
