Don't Ignore That Check Engine Light—Here's What You Need to Know
May 6, 2025
At Jim Brangham Auto Repair in Cathedral City, CA, we Understand how tempting it is to ignore a check engine light—especially if your car seems to be running fine. But that little light on your dashboard is a warning. It means something isn’t right, and waiting could lead to much bigger (and more expensive) problems.

What the Check Engine Light Really Means
When your check engine light turns on, your vehicle’s onboard computer has detected something abnormal in your engine, emissions, or other critical systems. Sometimes it’s something simple like a loose gas cap. Other times, it can point to serious issues like a misfire or sensor failure.
If the light is solid, your car is telling you it needs to be looked at soon. But if the light is blinking, that means there’s a more severe issue. If this happens, pull over safely, turn the engine off, and call us right away.
How We Test the Codes
When you bring your car in, we use high-end diagnostic scanners—not just simple code readers. These tools are very advanced (and very expensive) and allow us to go far beyond just pulling a code. Our team uses these tools to read live data, run system tests, and analyze exactly what’s going on under the hood.
Each trouble code is a starting point, but one code could point to several different possible problems. That’s why our testing and analysis process is so important—we take the time to do it right and find the true cause before making any repairs.
Why There’s a Diagnostic Fee
We do charge a diagnostic fee, which covers the time our experienced technicians spend analyzing your vehicle with specialized equipment. These scanners cost thousands of dollars and require ongoing updates and training to use correctly. The fee ensures your car gets an accurate diagnosis—saving you money in the long run by fixing the issue the right way the first time.
Don’t Wait—Get It Checked Out
A check engine light doesn’t just go away—it will get worse and leads to more damage. Taking care of it now can prevent serious repairs later.
If your check engine light is on, call Jim Brangham Auto Repair in Cathedral City, CA at 760-321-7040. Our team is here to help with expert diagnostics and honest service you can trust.

What Does the Ignition Coil Do? Your ignition coil takes the battery’s low voltage and turns it into the high voltage needed to create a spark in your engine. That spark lights the fuel in your engine so your car can run. If your ignition coil isn’t working right, your engine may misfire, run rough, or even stop running altogether. Signs You Might Have a Bad Ignition Coil If your car is hesitating, stalling, shaking, or your check engine light is on, it could be due to a faulty ignition coil. You might also notice a drop in fuel efficiency or poor acceleration. These issues can damage other parts of your engine over time if not fixed. Why Servicing Your Ignition Coil Saves Money Catching ignition coil problems early can save you from much more expensive repairs down the road. A misfiring engine can damage your catalytic converter, which is one of the most expensive parts on your car. Replacing a coil is far cheaper than replacing the entire exhaust system or engine components that get stressed when the coil fails.

If your vehicle is showing signs of trouble or the check engine light is on, bring it in. We’ll pinpoint the problem, explain your options, and only recommend repairs you actually need.

These small parts might not seem like much, but they play a big role in keeping you safe on the road. At Jim Brangham Auto Repair in Cathedral City, CA, we want drivers to understand why tie rods and tie rod ends are so important—and what happens when they wear out. What Do Tie Rods Do? Your vehicle’s tie rods connect the steering system to the wheels. They help your car turn left, right, and stay in control. Tie rod ends are the parts that link to the wheel assembly and allow movement and flexibility while keeping the wheels aligned. Why Worn Tie Rods Are a Safety Risk If a tie rod starts to fail, you might notice strange tire wear, a shaky steering wheel, or even trouble staying in your lane. A completely broken tie rod can cause you to lose steering control , which is extremely dangerous —especially at higher speeds. That’s why regular inspections and timely repairs are key to staying safe. How We Catch the Problem Early At Jim Brangham Auto Repair, our technicians check your steering and suspension systems as part of routine Digital Vehicle Inspection. We’ll let you know if your tie rods or tie rod ends are loose, damaged, or in need of replacement. Fixing the issue early not only protects you but also helps avoid damage to your tires and alignment.

One important part that helps your engine come to life is the starter. At Jim Brangham Auto Repair in Cathedral City, CA, we help drivers stay on the road by fixing issues like bad starters before they become bigger problems. What Is a Starter? The starter is a small electric motor that turns your engine on. When it works correctly, your engine starts quickly and smoothly. But if your starter is going bad, your car may hesitate, click, or not start at all. Signs Your Starter Might Be Failing If you hear a clicking sound when you turn the key, or if your lights come on but the engine won’t turn over, your starter could be the issue. Other times, your car might randomly fail to start even though the battery is fine. Why Fixing It Matters A bad starter can leave you stranded, especially in the hot California heat. Getting it checked early can prevent you from being stuck with a car that won’t start. Our team can test your starter, battery, and electrical system to find the problem fast. Reliable Starter Repair in Cathedral City At Jim Brangham Auto Repair, we provide honest answers and quality work. Whether it’s the starter, battery, or another part of your ignition system, we’ll make sure your vehicle is safe and ready to go.

It makes sure your car shifts gears smoothly whether you’re driving to work or taking a road trip. But like engine oil, your transmission fluid needs to be changed to keep everything running right. Why Transmission Fluid Matters Transmission fluid keeps all the moving parts inside your transmission cool and well-lubricated. Over time, this fluid can get dirty, lose its strength, and stop protecting your transmission the way it should. If this happens, you might notice rough shifting, slipping gears, or strange noises. What Is a Transmission Fluid Flush? A transmission fluid flush removes the old, dirty fluid and replaces it with clean, fresh fluid. This helps prevent wear and tear, improves gear shifting, and extends the life of your transmission. It’s one of the smartest ways to avoid costly repairs down the road. When Should You Get a Fluid Flush? Most vehicles need a transmission fluid flush every 30,000 to 60,000 miles, but it depends on your car, how you drive, and where you live. Hot weather here in California’s Coachella Valley can be tough on your transmission, so staying on top of this service is important. Trust Jim Brangham Auto Repair At Jim Brangham Auto Repair in Cathedral City, CA, we’re experts in transmission service, repairs, and fluid flushes. Our team will check your transmission fluid and let you know if it’s time for a change. Taking care of your transmission now can save you from big problems later.

At Jim Brangham Auto Repair in Cathedral City, CA, we help drivers understand the parts that make a difference—like this one. What Does the EGR Valve Do? EGR stands for Exhaust Gas Recirculation. The valve takes a small amount of exhaust gas and sends it back into the engine. This helps reduce harmful emissions and keeps the engine from getting too hot. What Happens When It Fails? If your EGR valve gets stuck or clogged, you might notice your engine idling rough, slowing down during acceleration, making knocking noises, or turning on the check engine light. A bad EGR valve can also lead to failed smog tests, which are required in California. How We Can Help At Jim Brangham Auto Repair, we use testing and analysis to check for problems with the EGR valve. If it’s dirty or not working, we can clean or replace it. This helps your engine run better and cleaner—and keeps you legal on the road. If your check engine light is on or your car isn’t running quite right, give us a call. Call Jim Brangham Auto Repair at 760-321-7040 in Cathedral City, CA today to schedule service. We’re your local experts for engine repair, smog testing, and honest auto care.

At Jim Brangham Auto Repair in Cathedral City, CA, we’re here to break it down so you can understand how it works and what to watch for. The Fuel Gauge The fuel gauge shows how much gas is in your tank. If it starts acting strange—like jumping around or getting stuck—it could be a sign of a bad fuel level sensor. It’s a small part inside the tank, but if it fails, you won’t know when you’re low on gas. The Fuel Pump The fuel pump sends gas from the tank to the engine. If your car struggles to start, stalls, or feels sluggish, the pump might be going bad. Fuel pumps can wear out over time, especially if you often drive on a nearly empty tank. The Seals and Hoses Rubber seals and hoses help keep the fuel system sealed tight. If they crack or wear out, gas vapors can escape or even leak, which isn’t safe. These parts can dry out in the desert heat, so it’s important to check them during regular maintenance. Keep Your Fuel System Healthy If you notice strong fuel smells, trouble starting your car, or issues with the fuel gauge, it’s time to bring your vehicle in. We’ll perform testing and analysis to check for leaks, bad pumps, or electrical problems. Call Jim Brangham Auto Repair in Cathedral City today to schedule your next service. We’re your trusted local shop for engine repair, fuel system service, A/C repair, and smog testing!

At Jim Brangham Auto Repair, we help drivers keep their cars in top shape with regular service intervals and our very own digital vehicle inspections. Why Are Service Intervals Important? Every car has a schedule for maintenance, like changing fluids, replacing filters, checking brakes, and inspecting key parts. Sticking to this schedule helps prevent breakdowns and keeps your car running smoothly. Skipping maintenance can lead to worn-out parts, poor gas mileage, and costly repairs that could have been avoided. The Benefits of Digital Vehicle Inspections At Jim Brangham Auto Repair, we use Digital Vehicle Inspections (DVI) to give you a clear, easy-to-understand report on your car’s condition. With photos and simple explanations, you’ll see exactly what needs attention and what’s in good shape. This helps you make smart choices about your car’s care, so there are no surprises when it comes to repairs. How Regular Maintenance Saves You Money Fixing small problems early prevents them from turning into big, expensive ones. Changing a timing belt or water pump on time is much cheaper than dealing with a blown engine. Keeping up with oil changes, brake checks, and fluid flushes helps your car last longer and avoids costly breakdowns. Keep Your Car in Great Shape Regular maintenance and digital inspections take the guesswork out of car care.

If you’ve noticed fluid leaking from your struts, it’s a sign that something isn’t right. At Jim Brangham Auto Repair in Cathedral City, CA, we’re here to explain why this matters and how it can affect your car. What Are Struts and What Do They Do? Struts are part of your suspension system, working alongside shocks to absorb bumps and keep your tires in contact with the road. They also help maintain your vehicle’s stability when turning, stopping, or driving over rough terrain. Why Are Leaky Struts a Problem? Struts contain hydraulic fluid that helps them absorb impact. When they start leaking, they lose effectiveness. This can make your ride feel rough and bumpy because your car won’t absorb shocks as well. You might also notice that your car feels unstable, especially when turning or stopping. Worn struts can cause uneven tire wear, making your tires wear out faster and leading to costly replacements. Bad struts also affect braking, meaning it can take longer for your car to stop, which can be dangerous. How Do You Know If Your Struts Are Leaking? If you see fluid near your tires, feel excessive bouncing, or notice that your car doesn’t handle as well as it used to, your struts might be the issue. Getting them checked early can prevent bigger safety concerns and expensive repairs. Get Your Suspension Checked Today Leaky struts don’t fix themselves. Waiting too long can lead to more costly repairs and unsafe driving conditions. If you think there’s a problem, visit Jim Brangham Auto Repair in Cathedral City, CA for a thorough inspection and expert service. Call us today at 760-321-7040 to schedule your suspension check!

At Jim Brangham Auto Repair in Cathedral City, CA, we want to help you understand why replacing it matters. What Does a Cabin Air Filter Do? Your cabin air filter blocks dust, pollen, and other pollutants from entering your car’s ventilation system. Over time, it gets clogged, making it harder for clean air to flow inside your vehicle. Why a Dirty Filter is a Problem Bad Air Quality – A clogged filter lets dust and allergens circulate, which can cause breathing issues. Weaker Heating & AC – Your system has to work harder, leading to poor performance. Musty Odors – Dirt and moisture buildup can create unpleasant smells. Foggy Windows – A blocked filter reduces airflow, making it harder to clear foggy windows. When to Replace It Most filters should be changed every 15,000 to 30,000 miles, but if you notice bad smells, weak airflow, or allergy symptoms, it may be time for a new one. Our team at Jim Brangham Auto Repair can check it for you. Stay Comfortable with a Fresh Filter Replacing your cabin air filter helps you breathe easier and keeps your car’s ventilation system working properly.
