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.

Automotive Tips from S T Foreign Auto Service: Alignment Inspection

Uneven tire wear, the car pulling to one side or a steering wheel that is off-center are signs for Syracuse drivers that their wheels may be out of alignment.

When doing an alignment inspection, the service advisor at S T Foreign Auto Service will inspect your tires for uneven wear as well as suspension and steering parts for signs of wear or damage. He?ll also compare your current alignment with the vehicle manufacturer?s settings.

Your vehicle owner?s manual will have a recommendation for when to check alignment. Of course, this recommendation is based on normal driving. If you have been in a crash, hit a curb/pothole, frequently drive off-road around Syracuse, or notice any symptoms of misalignment, have your S T Foreign Auto Service service advisor perform an important alignment check.

When "Oh, no!" Turns Into, "All right!"

Things we don't expect happen to our vehicles. And let's face, no one really wants to spend money on an unexpected repair. But if you are putting off going to your vehicle repair facility because you're dreading bad news, you might just be putting off some good news.

There was one minivan driver who'd had the same van for years and never had a problem with the power sliding doors.  Then one day, the electrical switches in the door pillars stopped working.  The key fob would still open them, but the door switches wouldn't do a thing.

Of course, the van driver feared the worst: an electrical problem, a major computer failure, mice chewing up the wires.  So, he put off going into the repair facility for a couple of months.  One day, it was time for his regular oil change and the service advisor asked him if there was anything else going on with the van.  The owner mentioned the door problem but said he didn't want to spend a fortune on it.

He waited for his van, and it wasn't long before the service advisor came out with good news. The doors weren't working because a switch on the overhead console had been turned off.  (It was a safety feature to allow parents to disable them.) The owner had accidentally switched it when he was unloading the van.  It was the first thing the technician had checked. Flip the switch back and all was working as usual.

Another example? A mother was driving a minivan with her two kids inside on a hot day when she felt the front end shaking violently as she drove down the road. Fearing something major had broken in the van (and fearing for the safety of her kids), she pulled into a fast-food restaurant parking lot and started to look underneath to see if it was anything obvious she could see.

She couldn't see any broken parts, but she also didn't feel safe getting back in the van with her kids.  So, she called her local service facility and asked if they could send someone to look at it.  When the technician arrived, he took it for a test drive on the same road on which she'd described having the trouble.  Then he put her van up on the lift.  His conclusion?  Nothing was wrong with her van.  It was the street she was driving on.  Crews repairing it had left the surface full of potholes, and that was causing her rough ride.

Ultimately, what these two drivers feared would be an expensive trip to the shop resulted in each driver getting different news than they had expected.  One learned something new about his vehicle.  The other?  Well, the technician saw that her tires were badly worn and convinced her to get them replaced, perhaps preventing an accident and giving peace of mind for a mom with two kids.

Keep Your Cool in Syracuse

Syracuse drivers rely on their vehicle's coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle engine and absorbs heat. The mixture then flows out to the radiator where it's cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.

There's a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that's easily reached inside your vehicle's engine, so it can turn to steam which does not conduct heat as well and is harder to contain.

Also, if it's freezing outside in Syracuse, the water in your engine could freeze while your vehicle is sitting out in the NY cold.

So, if you remember your high school chemistry, you'll know that a mixture has both a higher boiling point and a lower freezing point than either component alone.

Coolant, or antifreeze, is specially formulated to keep your engine safe in a wide range of environmental and operating temperatures in and around Syracuse.

Whenever your vehicle is running, the coolant in the cooling system is working to keep your engine from overheating. When it's cold outside, the coolant acts as antifreeze to keep the fluid from freezing in your engine.

All that exploding fuel in your engine creates a lot of heat. Without coolant, the metal vehicle engine parts would expand so much that the engine would seize up and stop running. The parts could be broken or warp so badly they would have to be replaced. It could even be so bad that the whole vehicle's engine is ruined and has to be junked.

This is why it is critical that Syracuse drivers check coolant levels frequently and have their vehicle's cooling system inspected for leaks. Also your vehicle has a maintenance requirement for draining and replacing your coolant. These recommendations can vary widely, so check your owner's manual or ask us at S T Foreign Auto Service in Syracuse.

The reason Syracuse drivers need to change the coolant is that it has additives in it to protect the cooling system. As you can imagine, with all the heat, the cooling system's a pretty harsh environment. The additives keep the fluid from becoming corrosive and damaging the radiator and other vehicle cooling system components. Over time, the additives are depleted and the coolant just has to be replaced.

Many Syracuse auto owners ask our advisors at S T Foreign Auto Service why there are different colors of antifreeze. It is very important that you use the correct type of antifreeze. The different types of antifreeze – or coolant – are different colors so you don't mix them up.

They use different materials to make the cooling system, and they require different types of antifreeze to protect them.

So check with us at S T Foreign Auto Service in Syracuse or your owner's manual for the right kind because using the wrong coolant can void the warranty for your vehicle cooling system.
