Imagine waking up one morning with a stomach ache. You pick up the phone, call the doctor’s office and say, “I’ve got a really bad tummy ache. How much will it cost to make me feel better?” Of course you wouldn’t do that. You know that there could be a lot of reasons for your symptoms and that the doctor will have to examine you, ask some questions and probably run some tests before she can tell you what’s wrong and give you treatment options.

This same scenario plays out every day at MN auto repair facilities. When the cause of the concern isn’t obvious, the car will need to undergo a diagnostic examination. The typical car has about 30,000 parts, including several networked computers and miles of wiring. Finding exactly what is wrong can be very complicated and take some time. The most experienced technicians at Autotronics of St. Peter in St. Peter are the ones who tackle the difficult diagnostic jobs. Once they have determined the cause of the trouble, they can work out the plan for how to fix it and tell you how much it will cost.

When you think about it this way, it makes perfect sense that, 1) the Autotronics of St. Peter service advisor cannot provide an estimate before the diagnosis is done, and 2) there is a charge for auto diagnostic services in St. Peter. You expect to pay for an office visit to the doctor and for any necessary tests before you can be presented with your treatment options and costs; same goes for your vehicle.

We know it can be frustrating for St. Peter drivers when something is wrong with your car and you aren’t sure what is going to be involved in getting it fixed. We are passionate about helping you through the process, communicating with you at each step along the way.

Starting in 1996, Autotronics of St. Peter service technicians have been able to use a standardized diagnostic system to help determine what is wrong with a vehicle. This diagnostic system works in tandem with the Engine Control Modules for each vehicle’s engine. The Engine Control Module is a computer that monitors and controls many engine functions.

Sensors throughout a vehicle send readings to the Engine Control Module. These readings help the computer make adjustments in various vehicle systems to allow for constantly changing driving conditions and even to compensate for minor problems. However, if the computer encounters a situation it can’t adjust for, it turns on the Check Engine light. (The Check Engine light is called the “service engine soon” light on some vehicles.)

If the Check Engine light is burning steadily, it indicates a problem that needs to be taken care of soon. If it is flashing, however, the vehicle needs immediate attention at Autotronics of St. Peter. When the Check Engine light is flashing, the vehicle should not be driven at high speeds, haul heavy loads or tow a trailer. St. Peter drivers need to understand that doing so can cause major damage.

When a vehicle is brought to Autotronics of St. Peter in St. Peter because the Check Engine light is on, a technician will scan the Engine Control Module to learn why it turned the light on. The answer comes as a “trouble code.” The technician has access to software that allows him to enter the code and find out what it means. The software will also let your Autotronics of St. Peter technician know what might be causing the problem and how to diagnose it.

Notice that the trouble code does not tell your technician at Autotronics of St. Peter exactly what is wrong with the vehicle. It can only let him know where to start looking to find the problem.

Scanning a trouble code and determining what it means is fairly simple for the pros at Autotronics of St. Peter. But the ensuing process of actually diagnosing a vehicle’s trouble can take a skilled technician some time. Sometimes this can add up to a significant repair bill. Some vehicle owners mistakenly believe  that the “trouble code” is all they need and think they can then fix their vehicles themselves. Some have tried to save money by purchasing an inexpensive scanner, or they take their vehicles to an auto parts store that offers the scan for little or no cost.

These options are often not the money-savers they seem for St. Peter vehicle owners. They can end up costing the vehicle owner extra in unnecessary repairs and engine damage.

For example, the trouble code P0133 reads “Bank 1 sensor 1 circuit slow response.” Translated, that means the front oxygen sensor shows a slow response time in changing the mix of air to fuel. The seemingly obvious conclusion is that the sensor needs to be replaced. The vehicle owner purchases a sensor, installs it and happily goes on his way.

However, read the trouble again: a slow response time in changing the mix of air to fuel. Nowhere does this indicate that the sensor is bad. There are a lot of parts involved in changing the air-fuel mix, any of which could be causing a slow reaction time. Those include a bad or contaminated airflow sensor, an exhaust leak, a problem in the electrical system or a leak in the intake manifold. The sensor is merely relaying that the response time is slow; it doesn’t indicate where the trouble is.

So the vehicle ends up with an oxygen sensor it did not need, and the delay in repairing the actual problem may have led to further damage to the engine. Both are added costs for the vehicle owner.

Cheap scanners also don’t have the ability to read the history stored in an engine’s computer. This operating history contains clues that can help in diagnosing engine trouble since it can indicate a developing problem. Autotronics of St. Peter invests a lot of money in high-end diagnostic equipment so that we have access not just to service codes but also to the operating history of the engine.

On-board diagnostics, then, are a tool to help diagnose what is wrong with a vehicle. They cannot specify what part needs to be fixed or replaced, and they cannot replace a well-trained and well-equipped service technician.

Unless you are a trained mechanic, it’s good auto advice to use Autotronics of St. Peter for your car care. In the long run, it can save you time, unnecessary expense and frustration. Autotronics of St. Peter can also help you keep up with your scheduled preventive maintenance, which can also save you on repair bills by alerting you to potential problems before they get expensive.

Fuel filters clean the dirt, dust and debris out of your fuel. Both gasoline and diesel-powered engines have them. The fuel filter is located in the fuel line between the fuel tank and the vehicle engine.

St. Peter auto owners don’t need to filter their fuel because it has lots of grit in it; they need to filter it because it has some grit it in. Any dirt is bad for your engine. The cleaner the fuel, the better your vehicle engine will run.

Over time, the small amounts of rust, dirt and contaminants in your fuel settle out inside the fuel tank. After about five years, this can amount to a quite a bit of sediment. This means that as your vehicle ages, your fuel filter has to work harder to screen your fuel: more sediment in your tank means more potential for grit in your fuel.

The harder your fuel filter works, the more often it needs to be replaced. Check with your owner’s manual to find out how often it should be serviced and how long you can expect it to last. St. Peter drivers should change it before it becomes clogged. Your friendly and knowledgeable Autotronics of St. Peter service advisor can help you with recommended fuel filter replacement schedules.

Good vehicle care means following recommended schedules for preventive maintenance, including changing your fuel filters. Take the auto advice offered in every owner’s manual and have your vehicle regularly inspected at Autotronics of St. Peter. It may save St. Peter auto owners money by preventing costly repairs, but it will also repay them in improved safety and peace of mind.
