What is a TPS? (Throttle Position Sensor)

You know you have an accelerator pedal; step on it and your vehicle is supposed to go.  But did you know there is a part in your vehicle that keeps track of where the throttle is? It's called the Throttle Position Sensor, or TPS.

The TPS is a sensor that helps your vehicle figure out the right mix of air and fuel is reaching your engine.  It does that by keeping track of the throttle and sending that information to your vehicle's computer.  Other factors play a role in how well your engine is performing, including air temperature, how fast the engine is turning over and air flow. 

When the TPS isn't working right, you may find your vehicle won't accelerate or doesn't have the power you're expecting when you press on the accelerator.  In some cases, it may accelerate on its own.  Sometimes your vehicle won't go over a certain speed.  Your Check Engine light may go on.

Any of these symptoms should be checked out soon.  If your TPS stops working right, your vehicle may not be safe to drive.  Fortunately, most vehicles have a "limp home" mode that will allow you to get off a busy road to a safe spot. 

Your service advisor can let you know which TPS is the correct replacement for your vehicle.  Your shop may have to re-program the new TPS so it works correctly with other software in your vehicle.

It's a fact of life these days that computers control many of a vehicle's functions. The sensors that feed information to those computers help make your vehicle work the way it was engineered to and keep you motoring down the road safely and efficiently.

Steer Right in Fenton

Virtually all vehicles come with power steering, so many Fenton drivers have never driven a car or truck without it. Power steering assists you when you turn your vehicle steering wheel. Without it, it would be very hard to steer.

Now this power assist comes in a couple of forms. In recent years, a lot of vehicles have an electric motor that reduces steering effort and helps improve performance and handling.

The other kind of power steering is hydraulic. This is the kind most older MI vehicles — and a lot of newer ones — have. Power steering fluid is pressurized by a pump and is used to assist steering. Of course, vehicles need the right amount of fluid in the system. If it's too low, your steering is affected and you could damage your vehicle pump.

Also, power steering fluid can become corrosive over time and damage the pump, hoses and connectors, leading to leaks and repairs. Power steering service at Muffler & Go in Fenton includes removing the contaminated fluid and replacing it with fresh fluid.

A word for Fenton drivers about power steering pumps: Some are powered by an electric motor. Others are driven by the serpentine belt. A worn serpentine belt stresses all of the vehicle components it drives, including the power steering pump, so replace the belt at Muffler & Go as advised to avoid undue repairs.

Losing your power steering while driving in Fenton can be unsettling – just remember that you can still steer, it'll just be harder. Check with your service advisor at Muffler & Go to see if it's time to service your vehicle's power steering system.

In addition to power steering service, at Muffler & Go we offer comprehensive automotive services.

Ethics of Automotive Repair in Fenton

We're going to be talking about the ethics of automotive repair. It seems like news outlets really like hit-and-run reporting; they hit everyone from groceries stores to retail to physicians. And the Fenton automotive service and repair industry hasn't been given a pass either.

Unfortunately, every profession in Fenton has some bad actors that hurt the reputation of everyone else. On the automotive side, industry associations and professional licensing organizations are very committed to high ethical standards.

Yet some people remain uncomfortable with Fenton automotive service and repair. It may start with the fact that our vehicles are a big investment and we rely on them for so much in our lives. That alone guarantees our attention. And how well we understand the recommendations really impacts our comfort level.

If we understand what's recommended and the benefits of taking care of the work – and the pitfalls of putting it off – we'll have more trust in the recommendation. So communication is key. It's like going to the doctor; If she's using medical jargon and takes a lot of basic medical knowledge for granted, we have a hard time following her train of thought. It can be like that with your Fenton service advisor too. He's so familiar with all things automotive, he may forget you don't know a PCV from an EGT.

If you don't understand what your doctor's talking about: ask some questions. If you don't understand what your Fenton automotive advisor's talking about: ask some questions.

Let's go back to those ethical standards; when we hear a repair recommendation, we always ask ourselves, "Is this really necessary?" Well, here's the industry standard:

If a technician tells you that a repair or replacement is required it must meet the following criteria:

1. The part no longer performs its intended purpose
2. The part does not meet a design specification
3. The part is missing

For example, it you take your car in for a grinding noise when you step on the brakes, you may just think you need new brake pads. After the inspection, the technician at Muffler & Go says that you have a cracked rotor and need to replace it.

If you tried to get him to simply put new pads on, he would say that if you didn't want to replace the rotor; Muffler & Go would ethically have to refuse the repair.

To just put pads on a cracked rotor would have been very wrong. The brakes could've failed at anytime and needed to be repaired – not just have a band-aid slapped on them.

Now, looking at something not so serious, the technician may suggest repair or replacement if:

1. The part is close to the end of its useful life – just above discard specifications or likely to fail soon
2. To address a customer need or request – like for better ride or increased performance
3. To comply with maintenance recommended by the vehicle's manufacturer
4. Based on the technician's informed experience

Of course, the technician has the burden of making ethical recommendations and properly educating their customers. For the customer, if you are uncomfortable with a recommendation, ask some questions. More information is always a good thing.

Fall and Spring Checkup in Fenton

When I was a kid, my dad always made sure he took the cars in for Spring and Fall checkups. I was telling a friend that it's about time to get into Muffler & Go for a checkup and he said that he read on the internet that modern cars don't need seasonal service.

My friend is (technically) right about some things, but from a practical standpoint, a seasonal check up still makes sense.

Back when my dad was teaching me about how to take care of the family vehicle, most of them used a different weight of oil in the winter and in the summer. But most of today's modern engines run the same oil year round. High-tech engines and high-tech motor oils are better able to handle the seasonal changes.

Your owner's manual or Fenton service advisor at Muffler & Go can tell you the right oil to use.

Of course, you're concerned about the coolant or antifreeze. You don't want to overheat in the MI summer or freeze up in the winter. Your engine cooling system protects against both of these things. And modern coolant — 'antifreeze' as it's sometimes called — is up to doing both very well. It's designed to last for longer distances than most people drive in a year or two.

So how does a Spring and Fall check-up fit in? Let's start with Spring. Summer is coming. That means heat, more driving and road trips. It just makes sense to check your fluid levels and do a visual inspection to see that everything is up to snuff.

You may not be scheduled to drain and replace the coolant for some time, but you need to make sure you have enough coolant and that you don't have any leaks or hoses that are about to fail.

That's pretty practical: a check-up to see if there are any problems or emerging conditions that could later become a problem, like a cracked belt.

And the same principle applies for getting ready for winter. Cold weather means lots of failed batteries. It takes more power to crank up a cold engine, and cold also decreases the available cranking power the battery has available.

So a battery test in the Fall could tell you if you've got a battery that is running on its last legs. And of course, if you live where winter temperatures get below 45 degrees F (7 degrees C) or you have ice and snow, you'll want to consider changing to winter tires.

So Spring and Fall auto checkups at Muffler & Go are practical reminders to get ready for the demands of the hot and cold seasons to come.

And odds are that you have one or more routine services that are due anyway. Like a transmission service, brake or power steering fluid, differential service — stuff like that. Are your wiper blades still good? Are your headlamps starting to dim?

So Spring and Fall, change your clocks, replace the batteries in your smoke detectors and get a check-up for your cars.

See, dad was right again.

Come and see us at Muffler & Go for your Spring and Fall automotive checkup.
