Diagnosing Your Vehicle at Autotronics of St. Peter in St. Peter

When we St. Peter residents get a car repair bill, we really shouldn’t be surprised to find “diagnostic fees” as one of the line items. When we get a computer fixed, there is usually a charge for the time it takes to diagnose the problem. When we go to a medical doctor, most of his fee is for his ability to diagnose what’s wrong. It’s no different with our vehicles.

Some diagnoses are fairly simple. Brake repairs at Autotronics of St. Peter usually require only a visual inspection, for instance. But other problems are much more difficult to diagnose. An intermittent engine problem, for example, takes time and expertise to pinpoint.

Modern vehicles have multiple computers that monitor a variety of sensors throughout the vehicle. When one of those sensors has a reading that is higher or lower than the standard parameters, the computer turns on the Check Engine light. Technicians at a service center such as Autotronics of St. Peter in St. Peter can scan the engine’s computer for a trouble code. This code tells the technician which reading is too high or too low.

That’s where some St. Peter residents get confused. They think that this reading concludes the diagnosis, and they don’t understand why the diagnostic fee is as much as it is when all the technician did was to scan the computer. But the truth is the trouble code is only the beginning of the diagnostic procedure.

Remember, the trouble code only tells which reading is out of parameter. It doesn’t say what is causing the reading to be too high or too low. Your Autotronics of St. Peter service technician still has to find the underlying problem. It’s a lot like going to the doctor. He can take your temperature and discover that you have a fever, but that doesn’t tell him what is causing your fever.

Automotive diagnostic technology can cut down the time it takes to figure out what’s wrong with a vehicle that isn’t running right. But it doesn’t do away with the need for your friendly and knowledgeable Autotronics of St. Peter service technician to make a proper diagnosis. Car care, like medical care, still requires the human touch.

PCV Valve: What Is It?

Most St. Peter drivers know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.

PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.

When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. St. Peter vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in turn, can blow gaskets and damage seals, leading to oil leaks.

The waste gases that leave the engine are comprised of about 70% unburned fuel. They used to be vented off the crankcase into the atmosphere. But starting in 1964, laws mandated that these gases be recaptured. Manufacturers began installing PCV systems, which recycled the gases into the air intake system where they could be mixed with fuel and sent to the engine to be burned.

The PCV valve is a one-way valve attached to the crankcase. Waste gases exit the crankcase through the valve but cannot enter.

Over time, the waste gases leave deposits on the PCV valve that can gum it up. So it needs to be replaced occasionally. This is an inexpensive part of preventive maintenance that is often overlooked, but which can have very expensive consequences. It’s good auto advice to keep this little valve clean and working well.

In order to maintain efficient circulation, the PCV system also has a breather tube that allows clean air to enter the crankcase. This air is usually filtered through the engine air filter. But some vehicles have a separate air filter for the breather tube called the breather element. If this is the case with your vehicle, proper maintenance of the PCV will include replacing this element. To find out whether your vehicle has this type of PCV system, check your owner’s manual or ask your service advisor at Autotronics of St. Peter.

The PCV system reduces harmful vehicle emissions. The maintenance it requires is simple and inexpensive at Autotronics of St. Peter. A fouled or damaged PCV system can lead to serious engine damage for St. Peter drivers.

Let’s all learn to practice good car care. It’s good for our wallets, and it’s good for our MN environment.

Speak Up: Talking with Your Autotronics of St. Peter Service Advisor

About 80% of the vehicles on St. Peter roads today are behind on their preventive maintenance schedules. That translates to about 160 million vehicles in the United States that aren’t performing as well as they could be – thousands right here in MN. Some of the maintenance issues are minor. Others represent serious safety concerns.

There are many reasons St. Peter drivers neglect their routine car care. Some of the more common ones are complacency, lack of confidence, lack of trust and budget issues.

Modern vehicles are amazingly reliable compared to their older counterparts. They can run for years without any repairs, and we sometimes translate that to mean they don’t need any maintenance. The trouble is that without maintenance, parts in the vehicle are gradually wearing out, fluids are getting dirty, oil is developing sludge — a lot of stuff is happening that we can’t see, and it is destroying the vehicle. The first time we learn there is a problem, we have a major repair bill on our hands.

Older vehicles just couldn’t keep going without frequent maintenance; they broke down without timely vehicle care. Modern vehicles are designed to keep running even when they’re not fully healthy. Unfortunately, that convenience has led some of us to become complacent and ignore vehicle care — until we have to fix something. And fixing something today takes a whole lot more than it used to.

Some people in St. Peter just don’t feel comfortable taking their vehicles to their local St. Peter service center. They don’t know much about engines or auto mechanics, so they don’t know what questions to ask. They don’t want to appear foolish or ignorant.

Your physician doesn’t expect you to understand what a ligament is or how it works. But if you have a problem with one, she’s going to explain to you what it is, what’s wrong with it and how it can be fixed. It’s in her best interest as well as yours to do so. You’ll both feel more comfortable with the treatment.

That’s what you can expect from the pros at Autotronics of St. Peter. They have to be highly trained and work with a lot of complex, high-tech systems. They don’t expect their St. Peter customers to understand car care. So ask questions. You need auto advice from a service specialist, just as you need medical advice from a doctor and financial advice from a financial advisor.

Which brings us to the next concern: trust. A lot of rumors fly around St. Peter about auto repair scams. You may have heard about some local auto shops taking advantage of customers and replacing parts that weren’t broken. Frankly, this is just bad business practice. St. Peter auto service centers won’t stay in business long if they’re engaged in this type of activity.

It’s in the best interest of St. Peter service centers to diagnose a problem correctly and fix it right the first time. That’s how they keep their businesses open.

Trust must be earned. But just as it took time for you to establish a relationship and rapport with your doctor, it will take time to build a relationship with your service center.

Also, realize that when your friendly and knowledgeable service advisor at Autotronics of St. Peter recommends routine maintenance, he is generally relying on your vehicle manufacturer’s recommendations. In other words, your trust lies both with your service advisor and your vehicle manufacturer. You’ll find that most of the service recommendations from Autotronics of St. Peter you receive coincide with what’s in your manual.

Those recommendations were set up by the engineers who designed your vehicle, not Autotronics of St. Peter. The team at Autotronics of St. Peter is just offering you a friendly reminder — a helpful reminder really, since most of us don’t post our owner’s manuals to our calendars.

Money is behind most neglect of vehicle maintenance. First, they worry that they can’t afford it. Second, they worry that they’re being overcharged.

The simple truth is, car care is like health care. We can’t afford not to have it. Preventive maintenance is cheap compared to repair work. It extends the lives of our vehicles and saves us money on fuel. It also makes our vehicles safer to drive, which can prevent accidents. Putting off preventive maintenance can be very expensive.

St. Peter area service centers have to be competitive. Like any business, they can’t afford to overcharge customers or they go out of business. But vehicle care today does cost more in MN than it used to. Vehicles are more sophisticated, complex and high-tech. That means technicians have to be better trained. They have to purchase high-tech diagnostic equipment and tools. They have to keep up with the latest advances in vehicle engineering and subscribe to computer databases. Like any business, they also have labor costs, insurance, rent, utilities, taxes, office supplies, etc.

If you are strapped for cash, Autotronics of St. Peter can offer auto advice to help you keep your car running safely and manage your budget. For example, let’s say you need new brake pads, transmission service and a new cabin air filter. A technician can’t ethically recommend you delay brake service: that creates a safety hazard for you and other St. Peter drivers. You need to get that done now. But they can let you know if the transmission service can wait a month and how long you can put off changing the cabin air filter. They can also estimate what these services will cost. That gives you the time and information you need to save up for the other services.

The key to modern car care is preventive maintenance. Our modern vehicles are safer, more fuel efficient and more reliable than ever before. But to keep them that way St. Peter drivers have to be more proactive about caring for them. It’s good to know there are knowledgeable professionals at Autotronics of St. Peter who can help us do just that.
