What is TPMS? Why you need TPMS

What is TPMS? (TPMS)stands for: Tire Pressure Monitoring System Tire pressure monitoring systems (TPMS) are a safety device installed by the factory to alert the driver of an underinflated tire. The most common systems used is a sensor mounted inside the tire to measure tire pressure directly and then transmits this information wirelessly to onboard electronics.

Is it necessary to replace the TPMS sensors when a vehicle needs new tires?

It depends on the age of the sensors. By the time the tires are worn out, the TPMS sensors may be nearing the end of their useful service life — or they may not have enough remaining battery life to last another set of tires.

Does the law require replacing a bad TPMS sensor?

It depends on your state and local laws. There is no legal requirement (yet) at the national level to replace a bad TPMS sensor if the TPMS warning light is on or flashing. That’s a decision the vehicle owner has to make regarding their own safety. Obviously, if a TPMS system has one or more bad sensors, it can’t warn the motorist of a low tire. If any vehicle owner decides not to have the sensors replace when it’s recommended the owner may be asked to sign a waiver stating  that they won’t hold the service shop liable for any damage or injury from improperly inflated tires

Why do you need it? (this is my opinion)

Well for several reasons:
  1. NHTSA-National Highway Traffic Safety Administration ruled that all vehicle manufacturer’s that sell motor vehicles in the U.S must have a Tire pressure monitoring system installed since 2007.
  2. it helps you save on gas because you’ll know when your pressure is low.. low tire pressure causes you to waste gas because of the increased friction.
  3. It tells you when you may need to service your tires or sensors.
When the light is steady, it means you need to have your tire pressure checked. When the light is flashing, it means you need to have your TPMS checked. And by keeping the TPMS in good working order you’re less likely to have an unexpected tire blowout that can occur when the TPMS is inactive or not installed at all. Yes, it can be annoying but in my opinion, that’s a small price to pay when it comes to you and your families safety.

Tips and techniques for diagnosing starter circuit concerns | Search Autoparts

brushless motors are concerned, you simply put the magnets on the part that spins. Put the electromagnetic windings on the outside, sort of like an alternator with a permanent magnet rotor, only you’re feeding the stator instead of harvesting its energy. The brushless AC motors in hybrid vehicle transmissions work in a similar fashion, but they’re fed by AC current from an inverter instead of DC. A brushless DC motor needs some electronics to make it work because you have to feed pulses to the external fixed windings in such a way that they’re timed with the north-south swapping of the permanent magnets built into the rotor. Thus, you’re taking the DC and turning it into AC inside the motor. Brushless DC motor electronics have to use a sensor keep up with where the rotor is at any given time, and a Hall-Effect sensor is typically used for that. Furthermore, because of the electronics, you can’t simply reverse the polarity of the current you feed a DC brushless motor and expect it to spin backward unless its electronics have been set up to work that way.

This is a simple diagram of how voltage drop testing should be done.  Just make sure the starter’s spinning when the measurements are taken, and be sure to include every suspect connection. The conventional wisdom is .1v or less on the negative side and .5v or less on the positive side. Before any suspected starter issue is addressed, these types scenarios must be dealt with, and the battery itself must receive a clean bill of health as well.  The side post adapter and its gaggle of connections (right) can drop disastrous amounts voltage. Low voltage problems (due to voltage drop or a weak battery) can make short work of a once-healthy starter.  This commutator was destroyed by repeated starts with a battery that had barely enough voltage to start the engine.

Want to Bring Your Own Auto Parts to a Mechanic? Here are 5 Reasons You Shouldn’t

Looking for ways to save money on car repairs? Regularly maintaining your vehicle – think oil changes and tire rotations – is the best way for an automotive technician to keep an eye on your vehicle health. That way, items that require attention won’t be left to deteriorate to the point of major parts breaking, which could get far more expensive than your budget allows. Just like preventative dental care, regular car care can identify and stave off big, expensive issues. Another way to save on car repairs is by bringing your own auto parts to a mechanic. There’s often a 25-50% markup on parts, and that number will often be lower for high-dollar parts, and higher for low-dollar parts. The markup helps shops to pay their rent, employees, pay for pricey equipment, and to make some money – after all, they’ve got to remain in business, right? So, since it could save you a few bucks, you may be wondering, “can you bring your own parts to a mechanic?” In the long run, it’s actually not a great idea. So, Can You Bring Your Own Parts to a Mechanic? – Here are 5 Reasons Not To: 1.No Warranty

Let’s say you’ve found a great deal on brake pads at AutoZone, so you bring them to the shop for your mechanic to install. Seems harmless, right? Not so fast. If the brakes you bought wind up failing, you are responsible for those parts, because they won’t have been covered under the shop’s warranty. Why not? The shop may not have recommended those parts for your vehicle. Those parts could have been made with subpar materials or might fit your vehicle improperly, resulting in poor performance.

If you bring your own parts, shops can only warranty their own labor. This means they would re-install something that wasn’t installed properly, but they wouldn’t cover the parts you’d sourced within the warranty. Here’s another way to look at it, courtesy of Bob Chandler, Bonded Transmission & Auto Repair’s service advisor: “Would you bring your steak to the restaurant and ask them to cook it?” Sure, you could buy a steak yourself for much less than you’d pay for it at a restaurant, which would never allow you to bring your own. They wouldn’t be able to confirm its freshness and might be worried you’d complain about the taste when they would never have served you that type of steak in the first place.

2.The Shop Could Be Legally Liable for Failed Parts

If a shop had installed a part that you had bought, and that part failed and caused an accident, the shop could be held legally liable. Matt Weber, the owner of Clark’s Car Care, explained that a court will almost always rule against an auto-repair business. They would say it shouldn’t have installed a customer-supplied part whose performance it couldn’t guarantee. Why does that matter? Many shop owners have poured their life savings into their businesses. The liability for installing a part you had purchased, in order to save a few bucks, isn’t worth that risk to a business owner’s personal and professional livelihoods. For that reason alone, many shops will decline to install customer-bought parts. It’s unfair to blame them for not wanting to take the risk of installing the parts you’ve purchased.

3.You Could Be Wrong

Automotive repair businesses invest a great deal of money into diagnostic equipment. They also prioritize continuing education for their technicians. Unless you’re mechanically inclined, you likely won’t be able to pinpoint the issue. When there’s a sound coming from some unknown location, or when your check engine light is on, your vehicle is best left in skilled hands. They’ll be much more accurate in determining what’s wrong, and which part(s) will need replacing.

4.It’s a Hassle

What if you had bought the wrong parts, or if they’re incompatible with additional parts that the shop is providing? You’ll need to head back to the auto parts store, or wait while a replacement is shipped. No need for you to waste time ordering auto parts, and potentially packaging and shipping incorrect ones for return.

5.You Might Not Get the Best Parts for the Job

Auto-repair businesses have long-standing relationships with parts suppliers. Those relationships allow shops to call in favors for quick deliveries from local parts-distribution centers. Suppliers will also often recommend superior parts for the job. Sure, it may seem as though parts suppliers have a vested interest in recommending more expensive parts. In reality, they wouldn’t dare jeopardize an important relationship with a client (the shop) by recommending a poorly-performing part.

Parts supplier representatives receive training on the latest technology. They have the advantage of receiving real-world performance and warranty information from shop owners and operators. The relationship that your local auto-repair business has with its parts supplier is an advantage that the average vehicle owner wouldn’t likely have after having glanced at a couple of automotive forums. Here’s an example of Tuan, a vehicle owner who had requested OEM (original equipment manufacturer) parts for his Subaru. The shop owner had recommended a part that performs better and longer than his vehicle manufacturer’s parts.
