Why Your Oxygen Sensor Matters – And When to Replace It

May 29, 2025

At Jim Brangham Auto Repair in Cathedral City, we want your vehicle running safely, smoothly, and efficiently. One small but important part that helps with this is the oxygen sensor. You’ve probably never seen it—but it plays a big role in how your car runs every day.

What Does an Oxygen Sensor Do?

The oxygen sensor checks how much oxygen is in your car’s exhaust gases. This information tells the engine’s computer how to balance air and fuel inside your engine. If the mix is just right, your engine runs strong and clean. If the mix is off, your car might use too much gas, feel sluggish, or release more emissions.

Most vehicles have at least one oxygen sensor, but many modern cars have two or more. They’re often located in or near your exhaust system.

Signs of a Bad Oxygen Sensor

Over time, sensors can wear out or fail. If your oxygen sensor isn’t working, your car’s computer doesn’t know how to adjust the fuel properly. That can cause a variety of problems, including:

Poor gas mileage
Rough idling or stalling
Engine running rich or lean
Failed California smog test
Check Engine Light turning on

If your Check Engine Light comes on, it could be something simple—or something serious. That’s why it’s important to have it checked with professional testing and analysis.

Testing with Advanced Tools

At Jim Brangham Auto Repair, we use advanced, high-quality code scanners to read the exact trouble codes your engine is showing. Our diagnostic testing helps us figure out what’s really going on—because sometimes one code can point to a few different problems.

There is a diagnostic fee for this service, but it’s worth every penny to make sure the issue is found accurately the first time. It helps you avoid guesswork and unnecessary repairs.

Why Replacing a Faulty Oxygen Sensor Saves You Money

If your oxygen sensor isn’t working, your engine burns more fuel than needed. That means you’re wasting money at the pump. It can also cause damage to other parts like the catalytic converter, which is a much more expensive repair. Replacing a worn oxygen sensor helps your car run better and protects your engine long term.

Why Your Power Steering Pump Is So Important

October 28, 2025

When your power steering is working right, turning the wheel feels effortless. But if your wheel feels stiff or you hear a whining sound when turning, you may have low fluid or a worn-out pump. Why Low Power Steering Fluid Is Dangerous Driving with low or no power steering fluid can be unsafe. The pump needs that fluid to build pressure and help you steer. Without it, your wheel can become very hard to turn—especially when parking or driving slowly. That can make it harder to control your car in an emergency. Low fluid also causes damage inside the pump, since the fluid keeps it cool and lubricated. If the pump runs dry, it can wear out fast or even stop working completely. What could’ve been a small fix can turn into a much more expensive repair. The Difference with Electronic Power Steering Many newer vehicles use electronic power steering (EPS) instead of hydraulic. EPS uses an electric motor to help turn the wheels. These systems don’t need fluid and are more fuel efficient. Still, it’s important to have them checked now and then to make sure the sensors and motor are working correctly. Keep Your Steering Safe and Smooth No matter what kind of steering system your vehicle has, regular checks are important. If you notice stiff steering, whining noises, or see fluid under your car, don’t ignore it. At Jim Brangham Auto Repair in Cathedral City, CA , our ASE-certified team can inspect your power steering system, top off or replace the fluid if needed, and make sure everything is safe and working properly. Call Jim Brangham Auto Repair today at (760) 321-7040 to schedule your power steering inspection and service in Cathedral City, CA. We’ll help keep your car steering smoothly and safely for miles to come.

Why Differential Service Can Save You Money

October 16, 2025

What the Differential Does The differential is what helps your wheels turn smoothly when you go around corners. It lets each wheel move at a slightly different speed, which makes driving easier and safer. If your differential starts to wear out, you might hear grinding or whining sounds, or feel your car handle differently. It’s one of those parts you don’t think about until something goes wrong — and by then, it can get expensive to fix. Why Differential Fluid Service Is Important Inside your differential is fluid that keeps the gears cool and lubricated. Over time, that fluid breaks down from heat, friction, and dust — especially in California’s desert weather. When the fluid gets dirty, it can’t protect the parts anymore. If that happens, it can cause: Rough or noisy driving Gear damage Leaks or vibration Costly repairs down the road That’s why changing your differential fluid on time is so important. It’s a simple and affordable way to keep your car running smoothly. How Often Should You Change It? Most cars need differential service every 30,000 to 60,000 miles. If you tow, haul heavy loads, or drive in hot weather often, you might need it sooner. The good news? It’s quick, easy, and saves you a lot of money compared to replacing the whole differential. How It Saves You Money Fresh differential fluid reduces wear and helps prevent breakdowns. A full differential replacement can cost thousands, while a fluid service is just a small routine maintenance. Taking care of it early keeps your car safe and reliable — and helps your budget in the long run.
