Common Types of Warning Alerts Modern vehicles have warning lights that indicate everything from minor maintenance reminders to serious system failures. CheckEngineLight (CEL): The checkenginelight signals potential issues ranging from minor sensor malfunctions to major engine failures.
When today’s vehicles roll into the garage with a checkenginelight or a strange misfire, gone are the days of relying on guesswork. Learning the ATC Way Every auto mechanic school may offer diagnostic tools, but at ATC Surrey, instructors guide students through practical troubleshooting with real vehicles.
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.
However, the MAF sensor can become dirty, malfunction, or fail, leading to significant engine performance issues. The comprehensive guide below features step-by-step diagnostic and repair solutions for troubleshooting a faulty MAF sensor. Then, start the engine and monitor its performance, noticing any changes in behavior.
This list also needs to be compared to what lights on the dash or the information system is saying. No longer is it just the checkenginelight giving an indication; specific lights or the lack of lights can signify an issue as well as the vehicle manufacturer indications in the information system on the dash.
Sometimes, when a related air suspension part fails, the ECM may also activate the checkenginelight. Troubleshooting these advanced systems requires technical know-how, extra care, and tools, such as a test light, scanner, or multimeter.
Original Equipment Manufacturer (OEM) vs. aftermarket parts: While aftermarket gaskets are more affordable, original auto parts offer a precise fit and extended durability. 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.
