When the check engine light illuminates on your dashboard, it indicates that something in your car’s system needs attention. While some causes are minor, others require prompt repairs to prevent further damage. The important thing is to get to the shop for diagnostics so the issue can be identified and addressed ASAP. At Austin Auto Repair, we provide expert check engine light repair in the greater Austin, TX area. Here are five common reasons why your check engine light may turn on. Faulty Oxygen Sensor Oxygen sensors monitor the amount of unburned oxygen in your vehicle’s exhaust, and send data to the engine’s computer to adjust the air-to-fuel ratio, ensuring efficient combustion. When the sensor malfunctions, the engine may use more fuel than necessary, leading to poor gas mileage. Catalytic Converter Problems The catalytic converter reduces harmful emissions by converting exhaust gasses into less toxic substances. If it’s clogged or damaged, it can trigger the check engine light and reduce engine performance. Common symptoms of a faulty catalytic converter include sluggish acceleration and decreased fuel-efficiency. Malfunctioning Mass Airflow Sensor The mass airflow (MAF) sensor measures the air entering the engine, which helps determine the correct fuel amount for optimal combustion. When the MAF sensor malfunctions, it can cause poor fuel-economy, rough idling, and even engine stalling. Loose or Damaged Gas Cap One of the simplest reasons for a check engine light is a loose or damaged gas cap. The gas cap keeps your fuel system sealed. If it’s faulty, fuel may evaporate before your car gets the chance to run on it. Failing Spark Plugs or Ignition Coils Spark plugs and ignition coils are essential components for igniting the air-fuel mixture in your engine’s cylinders. When they fail, it can result in misfires, reduced power, and increased emissions. Regularly replacing spark plugs and coils as recommended by your vehicle’s maintenance schedule can help avoid this issue.

Your vehicle's transmission is one of its most critical components, responsible for transferring power from the engine to the wheels. Any issue with the transmission can lead to serious performance problems and, in severe cases, complete failure. Spotting early signs of trouble can potentially save you from more expensive repairs. At Austin Auto Repair, we provide expert transmission repair in the greater Austin, TX area. Here are four warning signs of a transmission problem. Slipping Gears One of the most common signs of transmission trouble is slipping gears. If your vehicle suddenly shifts out of gear while driving or struggles to stay in gear, it’s a sign that something isn’t right. You may also notice the engine revving higher than normal without a corresponding increase in speed. This can occur due to issues such as low transmission fluid or worn-out gears. Slipping gears should be addressed immediately, as it can make driving dangerous. Delayed or Rough Shifting If your car hesitates before shifting or makes jerky movements during gear changes, this is a clear indication of a transmission issue. You may feel a noticeable delay between pressing the gas pedal and the vehicle responding, or the vehicle might shift with a jolt. These symptoms can result from worn transmission components, low fluid levels, or internal damage. Strange Noises Unusual sounds such as grinding, whining, or clunking when shifting gears can signal transmission trouble. Automatic transmissions may produce a humming or buzzing noise, while manual transmissions might grind when shifting. These noises often indicate worn or damaged parts, such as gears or bearings. Ignoring these sounds can lead to further internal damage and a more expensive repair. If you hear any strange noises coming from your transmission, it’s time to have it inspected by the mechanic. Leaking Transmission Fluid Transmission fluid is essential for lubricating the transmission’s internal components and maintaining proper function. If you notice reddish fluid pooling under your vehicle, it could be a transmission fluid leak. Leaking fluid can lead to a host of problems, including overheating and insufficient lubrication, which can cause significant damage. It’s important to address leaks as soon as possible and ensure that the fluid is at the proper level to avoid severe transmission trouble.
