Simple Answers from Griesbach Auto Service INC. for Weston: Tire Pressure Monitoring System

Tire Pressure Monitoring

Question:
My tire pressure warning light came on recently. What does that mean?

Griesbach Auto Service INC. Answer:
It means that one or more of your tires has low air pressure. The dashboard warning light, which looks like a cross-section of a tire with some lines in it, comes on when the tire pressure is 20% below what the manufacturer recommends. So if your recommendation is for 35 psi (pounds per square inch), the light will come on when your pressure falls to 28 psi.

It's important to note that 20% below recommended pressure is significantly under-inflated. This means that you will be experiencing degraded handling and that your tire will be running hotter than it should. This can not only be a safety hazard, but your tires will wear prematurely and could even suffer a heat related failure.

Weston drivers should not use their Tire Pressure Monitoring System (TPMS) warning light as their trigger for checking their tire pressure. They should still check their tire pressure at least once a month.

Some Weston drivers mistake the tire pressure printed on the side of the tire as the recommended pressure for the vehicle. This is not the case. The information on the tire is the range the tire can handle. The correct pressure for your vehicle is on a plate or sticker on the driver's side door or door jamb. This is the pressure your tires should have to match the engineered handling capacity of your vehicle. Please note that the pressure may be different for your front and rear tires.

Your TPMS does not have a regularly scheduled maintenance interval. However, be aware that the batteries in the sensors mounted in each wheel will eventually die, illuminating the warning light and necessitating replacing the sensor. Sensors can also be damaged by road salt and other contaminants.

Some TPMS systems indicate tire pressures for individual wheels which will tell Weston drivers which tire is low – as long as the system has been reset after rotating the tires. Other systems will simply give a warning, and it is up to you to check all your tires (including the spare). For more information, please ask our friendly and knowledgeable Griesbach Auto Service INC. service advisors.

The government mandated TPMS systems to reduce tire-related accidents, property damage, injuries and deaths. The automotive professionals at Griesbach Auto Service INC. in Weston recommend that you have your tire pressure checked at least once a month to maintain your safety and increase tire life.

Spark Plugs

When to change Spark Plugs

The days when Weston or Wausau drivers changed their spark plugs every couple of years has ended. Back in the day, spark plugs really did wear out that often. A couple of things are different now…

First, spark plugs are made of better materials that last longer for Weston drivers and they're designed better. The second reason spark plugs used to have to be changed in vehicles and other autos was that they were fouled up with carbon deposits. The deposits built up when fuel wasn't burned completely. With modern engine management controls that just doesn't happen as often.

Engine control computers precisely time when fuel is injected into the engine and when spark plugs fire. Unless something's wrong, spark plugs just don't foul like they used to.

Electricity from the battery goes into a coil that allows power to build up to anywhere from 12,000 to 45,000 volts, depending on the vehicle. The engine management computer tells the coil when to release the power to the spark plug. The electricity travels through a wire from the coil to the spark plug. At the tip of the plug, a spark jumps between two electrodes and ignites the gas in the combustion chamber.

Some engines have more than one coil. Coils wear out and need to be replaced occasionally. Also, spark plug wires can wear out and need to be replaced.

Modern engines used around Weston and Wausau are delivering more power and better fuel economy all the time. That's largely credited to fast engine control computers, advanced sensors, electronic ignition and improvements to the lowly spark plug.

It'll be interesting to see where future developments take us. One last thought: it's to have the right kind of spark plug for your vehicle. Because engines are designed to run with different internal temperatures, spark plugs have different designs to work properly within those temperatures. Your Weston or Wausau, WI, service advisor at Griesbach Auto Service INC. will be able to get the right plugs for your vehicle. And he'll be able to advise you on when you should replace your spark plugs as well.
