Every experienced mechanic knows that troubleshooting car repairs is as much about instinct as it is about technical skills. But when he started the car, the CheckEnginelight began flashinga sign that something was seriously wrong. I had never seen a flashing CheckEnginelight before, Hugo admitted.
If youre graduating from automotive school and preparing to work with traditional and electric vehicles (EVs), understanding warning alerts is key. Todays vehicles rely on advanced electronic systems to monitor performance, safety, and efficiency. Here are some of the most common alerts youll encounter: 1.
When today’s vehicles roll into the garage with a checkenginelight or a strange misfire, gone are the days of relying on guesswork. This essential diagnostic technique helps modern mechanics decode real-time vehicle data, and it’s a key skill taught at our auto mechanic school.
Everyone knows that a checkenginelight usually means that something is terribly wrong with the vehicle. But, what about… Read more » The post CheckEngineLight Comes On And Off – What’s Causing It? appeared first on Motor Verso.
Service bulletins, more formally known as Technical Service Bulletins (TSBs), are documents issued by vehicle manufacturers to alert technicians to common issues found in specific makes and models. Unlike recall notices, TSBs typically address non-safety-related defects, from software glitches to persistent checkenginelight triggers.
Unlike other methods, smoke machines: Provide visual confirmation of a leak Locate multiple leaks at once Can test complex systems like turbochargers or fuel vapor lines Save time and eliminate guesswork This tool is indispensable for working on modern vehicles with intricate systems that are difficult to access or troubleshoot.
Modern vehicles rely on various sensors to monitor their performance across multiple spectrums. For instance, the mass air flow (MAF) sensor plays a critical role in metering the air flowing into the engine and informing the engine control module (ECM). If the checkenginelight reappears, further diagnosis is required.
Refine your diagnostic and repair processes with Identifix Direct-Hit , a game-changer when it comes to detailed wiring diagrams, vehicle-specific repair data, and technician-tested fixes. A crank no start diagnosis involves troubleshooting the underlying cause of a cranking engine that refuses to start.
A damaged MAF can affect the performance of your vehicle and make it risky to drive on the road. However, if you want to do some basic troubleshooting yourself, you will need to know how a MAF sensor works. Most vehicles have a platinum hot wire MAF sensor. It will also increase your fuel consumption.
With all vehicle electronics networked together, diagnostic trouble codes (DTCs) are a common occurrence. It’s the end of the month, and you’re wrapping up repairs on a vehicle. Also, the actual repair process of the removing of parts and disconnecting of sensors and modules and then moving the vehicle may itself add DTCs to the list.
The light turns on when the system components can no longer adjust the vehicle’s height or provide ride comfort. Using this information, the modules activate the compressor, which pumps compressed air into the air springs to raise or lower your vehicle for improved stability and comfort. No, it’s not safe.
But, this can add a new wrinkle to diagnostics and communication on the vehicle. First is the throttle body that controls the air entering the engine. Throttle Triage When dealing with throttle-by-wire issues, the most likely customer complaint you will hear is the vehicle will go into a limp mode that limits engine speed.
As a car owner, it’s essential to have a basic understanding of your vehicle’s electrical system. The electrical system in your vehicle consists of several components working together to power various features such as lights, radio, power windows and seats, and more.
And your checkenginelight pops on? That’s a sign something’s off with combustion, and you could have an engine misfire. Engine misfiring is a serious problem. It creates a mechanical strain on your engine parts, and if you don’t remedy it quickly, the problem can grow to much larger (and expensive) proportions.
An Illuminated CheckEngineLight It’s almost impossible to physically detect an EVAP leak. So when the leak detection pump in the exhaust system suspects a small EVAP leak event, it immediately turns the CheckEngineLight on. So, it’s best to contact a mechanic if your vehicle fails an emissions test.
If you notice your AWD system isn’t engaging as expected, it may be due to: Electrical sensor problems Worn-out AWD components Electrical system glitches These electrical issues can also cause your vehicle’scheckenginelight to turn on. But that’s not all!
Do you also see suspicious red-colored fluid puddles under your vehicle? The cost of replacing a gasket in these vehicles is higher than in a manual transmission car. Thats why you should have a mechanic check out your car at the first sign of trouble. Check for violent car jerks and grinding sounds from the transmission area.
This common issue in automatic vehicles can be caused by a range of reasons, from a transmission problem to low transmission fluid. We’ll also explain how a mechanic diagnoses and fixes this glitch so you know what to expect when you bring your vehicle in for repair. When they wear out, the reverse gear may slip or fail entirely.
If your car has been idling strangely recently, it might be time to check your idle air control valve. This valve’s malfunction can cause a number of problems, such as stalling, low fuel efficiency, and the appearance of checkenginelights. The engine may stall or run rough as a result at low speeds.

When a vehicle wont start, its more than an inconvenience, its a diagnostic challenge. While both are related to a failure to start, each points to different systems within the vehicle. In many cases, the vehicle will offer subtle hints. In automotive training, you’ll learn how to work with modern vehicle systems.
But, what happens when you follow the directions and the process still wont initialize or complete or a malfunction light comes on? Troubleshooting the problem comes down to knowing the failure, vehicle or fixtures. Know the Vehicle Before you start any ADAS calibration, look to see what ADAS features are on the vehicle.
