When the check engine light on your car illuminates, a diagnostic trouble code (DTC) usually appears next. The onboard diagnostic (OBD-II) system of the car uses these codes to help diagnose problems with the engine, transmission, and emissions systems. Knowing the meaning of these codes can help you identify potential problems with your car and save time, money, and stress. When you need computer diagnostics and auto repair, visit Integrity Fleet Service in Gilbert, AZ. How Diagnostic Codes Work Through several sensors, the OBD-II system keeps an eye on the operation of your car. A sensor sets off the check engine light and registers a diagnostic code when it notices abnormalities, including engine misfires or emissions failure. Every code has a distinct meaning, making it easier for mechanics to identify the issue. Common Diagnostic Codes P0420: Catalyst System Efficiency Below Threshold This suggests there may be an issue with the catalytic converter, which helps regulate the emissions from your car. Reduced performance and higher emissions may result from a malfunctioning catalytic converter. P0300: Random/Multiple Cylinder Misfire This number indicates that more than one cylinder of your engine is misfiring. The causes can include everything from fuel delivery issues to spark plug troubles. P0171: System Too Lean (Bank 1) This means the engine's combustion process is using too much air and not enough fuel, which could be the result of an oxygen sensor malfunction or a vacuum leak. What Should You Do? It is important to take your vehicle to a mechanic who can read the diagnostic code if you receive one. Certain problems can be easily resolved, such as a loose gas cap that causes an emissions alert, while other problems might be more complicated and call for specialized equipment to identify and correct. Ignoring a diagnostic code or check engine light can eventually result in more significant problems.

Your vehicle's catalytic converter plays an important role in reducing harmful emissions and helping your vehicle run smoothly. When it becomes damaged, it can lead to a variety of issues that affect your car's efficiency and functionality. Identifying the signs of catalytic converter damage early can save you from costly repairs and potential breakdowns, which we explore below. If you need catalytic converter repair, contact Integrity Fleet Service in Gilbert, AZ for the job. Burnt Oil If you notice thick, dark exhaust smoke or a distinct burning oil smell, it could indicate that your catalytic converter is not functioning properly. This happens because a failing catalytic converter can cause the engine to burn oil more rapidly, leading to this noticeable symptom. Antifreeze in the Exhaust Another sign of catalytic converter damage is the presence of antifreeze in the exhaust. This occurs when there is a leak in the head gasket, allowing antifreeze to enter the combustion chamber and burn alongside fuel. The result is a sweet-smelling white smoke coming from the exhaust pipe. This indicates a serious issue with the catalytic converter and the engine, as burning antifreeze can cause significant damage over time. Overheating When the catalytic converter becomes clogged, it restricts the flow of exhaust gases, causing excessive heat buildup in the engine and exhaust system. This can lead to your vehicle overheating, which may result in engine damage if not addressed promptly. You might notice the temperature gauge rising or the engine running hotter than usual. Physical Damage Physical damage to the catalytic converter can occur due to road debris, speed bumps, or accidents. Signs of physical damage include visible dents, cracks, or rust on the exterior of the converter. These damages can cause the converter to leak or become less effective in reducing emissions, leading to increased exhaust noise or decreased engine performance. If you notice any physical signs of damage to your catalytic converter, it's important to have it inspected by a professional technician to assess the extent of the damage and determine if replacement is necessary.

When the temperature rises, keeping your tires protected from heat is imperative. Hot weather can damage your tires, impairing performance and safety, from increased tire pressure to rapid tread deterioration. We look at simple tips to protect your tires from the heat below. When you need new tires, contact Integrity Fleet Service in Gilbert, AZ for the job. How Heat Affects Your Tires Tire pressure rises with temperature, which, if not properly checked and controlled, can result in overinflation and blowouts. Prolonged heat exposure can also speed up tire rubber degradation, leading to premature wear and decreased traction on the road. Elevated temperatures have the potential to worsen pre-existing tire deterioration, including cracks or bulges, increasing the likelihood of failure. Avoid a Blowout Make sure your tire pressure is in line with the manufacturer's suggested levels by using a trustworthy gauge to check it regularly. Properly inflated tires can withstand the rigors of summer driving and are less likely to overheat. Look for wear indicators on your tires, such as bulges, cracks, or uneven tread wear, and replace them as necessary. Steer clear of overloading your car and traveling at high speeds, since these actions can exacerbate tire stress and heat buildup. Best Tires for Hot Climates Look for tires that are made specifically for hot weather; these are frequently referred to as "summer" or "all-season" tires. Because the tread compound on these tires is designed to withstand higher temperatures, they offer better traction and grip on heated pavement. Because they can typically survive the heat and friction of hot roads better, tires with a higher treadwear rating should also be taken into consideration. Choosing tires with broader channels and deeper tread grooves can also aid in better heat dissipation, lower the chance of overheating, and delay premature wear. We have an enormous assortment of tires in stock at Integrity Fleet Service to satisfy your needs.

An overheating diesel engine is more than just a nuisance; it is a warning sign of trouble to come. Below, we examine the most common causes of diesel engine overheating, as well as how to prevent them. When you need diesel engine repair, contact Integrity Fleet Service in Gilbert, AZ for the job. Clogged Radiator In the radiator, debris, dirt, and other pollutants can accumulate over time, restricting coolant flow. When the radiator becomes clogged, heat exchange efficiency declines, resulting in higher engine temperatures. Regular maintenance, such as draining the radiator and checking for obstructions, can help prevent this issue. The radiator can also be kept clean by maintaining enough coolant levels and using high-quality coolant. Malfunctioning Thermostat To keep the engine working at the right temperature, the thermostat regulates the flow of coolant through it, opening and closing as necessary. When the thermostat malfunctions, it may become stuck closed, preventing coolant from properly circulating and causing overheating. It may also become jammed open, causing the engine to run hotter than necessary, resulting in decreased fuel efficiency. Regular inspection and replacement of the thermostat can help prevent this. Engine Coolant Leak The engine coolant maintains the engine's temperature and avoids overheating. However, leaks can occur because of malfunctioning hoses, gaskets, or radiator components, allowing coolant to escape and lowering system performance. When coolant levels drop, the engine no longer receives adequate cooling, resulting in higher temperatures and potentially overheating. Engine damage can be avoided by regularly inspecting for coolant leaks, such as puddles under the car or low coolant levels in the reservoir. Damaged Radiator Hose Engine coolant is transferred by radiator hoses. Radiator hoses can degrade, split, or leak after prolonged exposure to heat, pressure, and contaminants. When a radiator hose is damaged, coolant can leak out, causing low coolant levels and poor cooling system performance. Because of this, the engine could overheat and damage critical components. Examine the radiator hoses for evidence of wear, such as cracks, bulges, or soft spots.

Misfiring engines can spell trouble for your truck. We explain why your engine might be misfiring and how you can fix it below. When you need diesel engine repair, contact Integrity Fleet Service in Gilbert, AZ for the job. What Is an Engine Misfire? An engine misfire happens when one or more cylinders in the engine fail to ignite the fuel-air mixture at the appropriate time. This disturbs the smooth firing sequence, resulting in anything from unsteady idle to a significant reduction in performance. Causes can range from old spark plugs to malfunctioning ignition coils or dirty fuel injectors. Damaged Spark Plugs Misfires are most commonly caused by damaged spark plugs. These small but vital components are critical in igniting the gasoline-air mixture within the engine cylinder. When spark plugs get damaged or worn out, they struggle to deliver the necessary spark, resulting in misfires. Common signs of a broken spark plug include rough idling, poor acceleration, and even reduced fuel efficiency. Regular inspections and prompt replacement of spark plugs are critical maintenance tasks for keeping your engine working properly. Dirty Fuel Injectors Fuel injectors direct fuel into the engine's cylinders, ensuring efficient combustion. Over time, dirt, debris, and carbon deposits can accumulate on the fuel injectors, interfering with the precise fuel distribution required for best engine performance. When fuel injectors become dirty, the fuel-air combination is not optimal, causing misfires and other performance difficulties. Regular maintenance, such as using fuel system cleansers and keeping fuel filters clean, will help prevent deposits and keep your engine running smoothly. Faulty Ignition Coils Ignition coils provide a high-voltage spark, igniting the fuel-air combination in the engine cylinders. When an ignition coil fails, it may produce uneven or weak sparks, leading to misfires. Rough idling, slow acceleration, and reduced fuel efficiency are all common signs of a malfunctioning ignition coil. Regularly inspect and repair broken ignition coils to avoid misfires Diesel Engine Repair in Gilbert While diesel engines tend to last longer without any need for major repairs compared to gasoline engines, they aren’t without faults.
