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.

Cold Weather Vehicle No-Nos (Items to Avoid Storing in a Freezing Vehicle)

It's always easier to leave a few things in your vehicle so you'll have them on hand.  But in cold weather, while it's a good idea to carry items such as a phone charger, blanket and shovel, there are some things you shouldn't store in your vehicle.

  • Medicines and drugs.  Cold temperatures can affect the chemical makeup of some drugs.  Avoid leaving them in a vehicle, especially those in a liquid form like insulin, eye drops and cough syrup.
  • Latex paint.  They are water based, and when they freeze, they get lumpy and lousy.  Your paint job will not be what you had in mind.
  • Cellphones and computers.  Most of these have lithium ion batteries.  If they get colder than freezing (0 degrees C, 32 degrees F), if you try to charge them, you'll more than likely ruin the batteries. 
  • Bottled water, soda, wine or beer.  OK, here's the scoop.  All of these can freeze and split the container they're in.  Yes, soda, wine and beer will take a lower temperature to freeze than water, but all of these can easily freeze if the mercury plunges low enough.  The problem isn't when they're frozen; it's when they unfreeze, drip out of their containers and leave you with a colossal mess. 
  • Musical instruments.  Guitars are made of wood.  When a guitar freezes and you bring it quickly into a warm room, you may hear cracking sounds that tell you that guitar will be not-so-gently weeping from the damage that can occur.  The same goes for wind instruments and others.  Don't ever subject musical instruments to quick temperature extremes.

 

Take a little time and effort not to leave these things out in a frigid vehicle.  You'll likely spend far more time and money tending to the resulting consequences than if you'd just brought them inside in the first place.

Positive and Negative (Battery Care)

You notice when your smartphone's battery starts to go weak on you.  It runs out of juice faster than it did when it was new.  Bet you pay attention to that pretty closely.

Unfortunately, many of us don't pay the same attention to the battery in our vehicles. If your battery got you through the cold-weather months, you might be thinking you're all set until next winter. But you might be surprised to learn this: Hot weather is harder on a battery than cold weather.  (Note: we're talking about a conventional vehicle here, not an all-electric, plug-in one.)

 The way your vehicle's battery holds a charge is that it has chemicals inside it, and they react with each other to produce electricity.  A vehicle battery discharges electricity and then needs to be recharged.  Unlike your smartphone that you plug in each night to charge, the way a vehicle's battery gets recharged is by using the mechanical energy of the engine.  It's a pretty cool system that's been around for a while.  An alternator changes the mechanical energy into electricity that then charges the battery.  And your vehicle is designed to charge it just the right amount with a voltage regulator. If your battery constantly gets too much voltage, it could stop holding a charge. 

Another way a vehicle battery loses its ability to hold a charge is when it gets hot.  In warmer weather, some fluids in your battery evaporate which can damage some of its internal components.  Then, you've got a dead battery.

Back to your smartphone for a second, it probably has a little indicator or maybe an app that shows you how healthy it is or how much charge it's holding.  Well, your service repair facility has equipment that can test your vehicle's battery for the same things.  If that test shows you need a new battery, then it's probably time to replace it.

A technician can also check to see your battery is being charged at the correct rate.  If you have a battery that is not sealed, a technician can check to see it needs more water added to it.  The technician will also make sure dirt or other contaminants aren't acting as electrical conductors and discharging the battery.  Plus, your battery's terminals may need cleaning.

Most people just forget about their vehicle's battery until there's a big problem with it. Here's one rule of thumb: expect a battery's life to be about 5 years. Just like you wouldn't want your smartphone to leave you without any way to make phone calls or send texts, you wouldn't want your vehicle to leave you stranded with no way to start it, would you?   

When it comes time to make that new battery choice, your service advisor can offer you some good options, taking into account the climate you drive in, what you use your vehicle for and what your budget is.  Hey, your smartphone's battery is all charged up.  How about calling your service advisor for an appointment right now?

The Right Stuff (Choosing Replacement Parts)

Let's face it.  Vehicles are complicated machines, each having thousands of parts.  And since they're subjected to heat, cold, vibrations, bumps and much more, these parts wear out and need to be replaced. 

When your service advisor says you need a new part, you may have many options.  Let's say you need a new muffler.  One choice would be to get exactly the same part that was installed when the vehicle was manufactured.  The advantages are that it will perform the same way as the one it's replacing and will likely last about the same amount of time as the original.

Some mufflers are made by the same companies that supplied the automaker when your vehicle was new (they call that an OEM part—Original Equipment Manufacturer).  And often those are the same as the part you'd buy from a dealer. A reputable vehicle service facility will know which ones these are because they replace mufflers all the time and do their homework.

The good news is there are many different mufflers available from several manufacturers.  These are called aftermarket parts. Some of them may use different metals or a different construction technique. Some may sound a little sportier while some may make your engine perform better.  Your service advisor will discuss what your driving habits are and help choose the part that's best for you.

You may be able to get a part that's better than the one originally installed.  Here's an example.  A repair shop discovered one owner's vehicle had developed cracks and leaks in the hoses that attach to the heater core.  They were made of plastic, and heat and pressure had caused the originals to crack.  The service advisor recommended they replace it with an aftermarket part that was made of aluminum instead, one that was more durable than the original part.

Some aftermarket parts cost more, some cost about the same or less.  Depending on how and where you drive and what you want out of your vehicle, you can decide to buy more economical parts which might be the best fit for your needs.  Or you may decide to upgrade to a better, more expensive part.
