But the Guy at the Parts Store Already Diagnosed it!

A check engine light (CEL) illuminated on your vehicle's dashboard can be a cause for concern and indicate potential issues with your vehicle's engine or emission systems. Many drivers turn to code readers or diagnostic tools to determine the underlying problem triggering the CEL. While code readers can be useful in providing codes that point to specific issues, it's important to understand that they may not always provide a complete diagnosis of the problem. Here are some reasons why a code reader may fall short in fully diagnosing a vehicle's check engine light: Limited Information: A code reader or diagnostic tool can retrieve diagnostic trouble codes (DTCs) stored in the vehicle's onboard computer system. These codes provide information about specific faults or malfunctions detected by the system. However, DTCs are often generic and may not always pinpoint the exact cause of the issue. Additional diagnostic steps, testing, and interpretation may be required to accurately diagnose the problem. Interpretation of Codes: Interpreting diagnostic trouble codes requires knowledge, experience, and expertise in automotive diagnostics. While a code reader can provide codes related to various components or systems, understanding the context, relevance, and potential causes of the codes is crucial for accurate diagnosis. Professional technicians have the training and expertise to interpret codes, assess symptoms, and conduct further diagnostic tests to identify the root cause of the problem. System Complexity: Modern vehicles are equipped with sophisticated electronic systems, sensors, and components that interact with one another to ensure proper operation. The check engine light can be triggered by a wide range of issues, including sensor malfunctions, emissions problems, engine or transmission issues, and more. A comprehensive diagnosis may require a thorough inspection of multiple systems and components beyond what a code reader can provide. Hidden or Intermittent Issues: Some vehicle problems may not trigger a diagnostic trouble code immediately or consistently. Intermittent issues or hidden faults that occur sporadically may not be captured by a code reader during a quick scan. Professional diagnostics involve thorough testing, monitoring, and analysis to uncover hidden or intermittent problems that may not be evident from a simple code reading. Diagnostic Tools and Equipment: Professional automotive repair facilities have access to advanced diagnostic tools, equipment, and resources that enable them to perform comprehensive diagnostics and pinpoint complex issues effectively. These tools, such as scan tools, scopes, meters, and software, provide in-depth data, real-time monitoring, and specialized tests to accurately diagnose the root cause of the check engine light. While a code reader can be a useful tool for retrieving diagnostic trouble codes and gaining initial insights into potential issues with your vehicle, it should be considered a starting point rather than a definitive diagnosis. For a complete and accurate assessment of your vehicle's check engine light, it's recommended to consult a professional automotive technician or repair shop with the expertise, experience, and resources to perform thorough diagnostics and identify the root cause of the problem.

Do Tires Expire?

Image
  Do tires expire is a question that our customers often ask. For years many motorists have relied only on tread depth to know when it is time to replace them. Unfortunately, the age of your tires is also a factor. Over time, tires can dry out and crack. Excessive heat and sunlight contribute to this and can cause tire to unexpectedly fail, even when there is plenty of tread remaining on the tire . Tire manufacturers offer different opinions regarding how long tires will last, but the National Highway Transportation Safety Administration (NTHSA) recommends that you replace tires after six years . How do you know how old your tires are ? The best way to know the age of your tires is to check the Department of Transportation (DOT) code. The manufacturer stamped it in the sidewall of your tire. DOT numbers identify the manufacturer and the make of tires, but they also tell you when the tires were made . The last four digits of your tires’ DOT code tell the month and year of manufa...

What is a Belt Tune Up?

Image
A Serpentine Belt is the rubber Drive Belt that causes the pullies on your car's Alternator, Air Conditioning Compressor, Water Pump, and Power Steering Pump to rotate and to create electrical and mechanical power. Rotation of the alternator creates your car's electrical power. Gas powered vehicles have one or more Drive Belts, at least one Belt Tensioner, and they may have one or more Idler Pulleys. Belt Tensioners insure that the Alternator, A/C Compressor, Water Pump, and Power Steering Pump continue to spin with the rotation of the engine. Idler Pulleys are simply pulleys that do not drive other components. Idler Pulleys are used to route the Serpentine Belt.  With use, a Serpentine Belt will stretch and wear.  Belt Tensioners and Idler Pulleys also wear, and this will cause additional belt wear. When a Serpentine Belt breaks, the components that it drives will not longer function. Because of this, Sant Automotive recommends that you replace your Serpentine Belt(s), Idler ...

What Do Spark Plugs Do?

Image
  Spark Plugs are the small electrical parts that provide the power to ignite the fuel in gasoline powered devices. As electricity passes between the Spark Plug's electrodes, gasoline ignites causing an explosion that powers your vehicle. Spark Plugs fire once every two engine rotations. This means that if your engine is running at 800 RPMs, your Spark Plugs will fire 400 times per minute. The heat produced by these explosions causes the Electrodes to wear which increases the gap between the Electrodes. The increased gap causes your vehicle to use more fuel to produce the same amount of power.  Worn Spark Plugs reduce Gas Mileage, and unburnt fuel will damage your car's Oxygen Sensors and its Catalytic Converter. Also, the longer that plugs stay in a vehicle, the more likely they are to become stuck in the engine's cylinder head. If a spark plug breaks, it can be very expensive and time consuming to extract it. For these reasons, Sant Automotive recommends that you change y...
