O2 sensor
"I had the code read it said an O2 sensor, and then the light went out in four days before that light came back on."
An O2 sensor is a part of your car that checks how much oxygen is in the exhaust. It helps the car's computer manage fuel use and keep emissions low. If it fails, it can cause the check engine light to come on.
An O2 sensor, or oxygen sensor, measures the amount of oxygen in the exhaust gases of a vehicle. It helps the engine control unit (ECU) optimize fuel efficiency and reduce emissions by adjusting the air-fuel mixture based on the sensor's readings.
oil filter
"Listener sent this in. Is the car manufacturer's oil filter a good choice?"
An oil filter helps keep the oil in your car clean by removing dirt and debris. Some people wonder if it's better to use the filter made by the car's manufacturer or if other brands are just as good.
An oil filter is a crucial component in an engine's lubrication system, designed to remove contaminants from engine oil. Using a manufacturer's oil filter can ensure compatibility and maintain warranty coverage, but aftermarket options may offer better performance or filtration.

direct injection
"...Newer vehicles have what we call direct injection, which is a high pressure fuel system."
Direct injection means the gas goes straight into the engine's combustion chamber, which helps the car use fuel more efficiently and can make it run better.
Direct injection is a fuel delivery system where fuel is injected directly into the combustion chamber of the engine. This method allows for better fuel efficiency and performance compared to traditional fuel injection systems.
high pressure fuel system
"...direct injection, which is a high pressure fuel system. So there's a secondary pump up on the engine itself."
A high pressure fuel system pushes gas into the engine at a stronger force, which helps the engine burn the fuel better and run more efficiently.
A high pressure fuel system is designed to deliver fuel at a higher pressure than standard systems, which is necessary for direct injection engines to atomize the fuel properly for combustion. This leads to improved efficiency and power output.
valve stem
"It's usually part of the valve stem. So if something's coming apart there, I'd be worried of the flat tire to be honest."
The valve stem is the part on your tire where you pump air in. It's important for keeping your tires inflated and working properly.
The valve stem is a small component on a tire that allows air to enter or escape. It connects to the tire pressure sensor and is crucial for maintaining proper tire inflation.
tire pressure monitoring system (TPMS)
"if your vehicle is equipped where it tells you the pressures of the tires are just the light. But, you know, we can ping with a little handheld tool"
TPMS is a system that checks if your tires have enough air. If one tire is low on air, it will warn you so you can fill it up and stay safe while driving.
A tire pressure monitoring system (TPMS) is a safety feature that monitors the air pressure in your vehicle's tires. If the pressure drops below a certain level, it alerts the driver, helping to prevent tire blowouts and improve fuel efficiency.
tire pressure sensors
"all four sensors or five sensors if there's one in the spare, determine if they're working."
These are small devices in your tires that check how much air is inside. They help keep your tires at the right pressure, which is important for safety and fuel efficiency.
Tire pressure sensors are devices installed in each tire that measure the air pressure and send this information to the vehicle's TPMS. They help ensure that the tires are properly inflated for safe driving.
battery life
"you can see the battery life or the battery charge of it. So you can see if it's getting weak, if the battery's getting weak,"
Battery life is how long a battery lasts before it needs to be changed. For tire sensors, it's important to check this so they keep working properly.
Battery life refers to the duration a battery can effectively power a device before it needs to be replaced or recharged. In the context of tire pressure sensors, monitoring battery life is important to ensure they function correctly.
three quarter ton truck
"...my truck's at three quarter ton. And so it has the higher capacity tires."
A three quarter ton truck is a type of pickup truck that can carry more weight than smaller trucks. It's good for hauling heavy items or towing trailers.
A three quarter ton truck is a classification of truck that can carry a maximum payload of approximately 1,500 pounds. These trucks are often used for heavier loads and towing compared to half-ton trucks.
PSI
"...And my tires said they were at 58 PSI when I left."
PSI means how much air pressure is in your tires. It's important to have the right amount of air in your tires for safe driving and better gas mileage.
PSI stands for pounds per square inch, a unit of measurement used to indicate the pressure of air in tires. Proper tire pressure is crucial for vehicle safety, fuel efficiency, and tire longevity.
overinflated tires
"...not overinflated tires, but we don't have the light on..."
Overinflated tires are tires that have too much air in them. This can make it harder to drive safely and can wear the tires out faster.
Overinflated tires occur when the pressure inside the tire exceeds the manufacturer's recommended level. This can lead to reduced traction, uneven tire wear, and a harsher ride.
hand wax
"But I will tell you, if you do actually take the time to hand wax your vehicle, it will look like it's a new vehicle when you're done. It's amazing what that little elbow grease will do."
Hand waxing is when you apply wax to your car's paint by hand to make it shiny and protect it. It can help your car look like it's brand new.
