What does service engine soon light mean?
The service engine soon light indicates a minor issue with the electronics or engine of a car and may also signify the need for scheduled service like oil or spark plug replacement. Some car manufacturers are using it as a substitute for the check engine light for minor issues.
What is the difference between service engine and check engine light?
The Service Engine Light alerts owners to upcoming expected maintenance, while the Check Engine Light indicates an unexpected problem with the engine or exhaust system.
Diagnostic code: The code that's stored in the vehicle's computer can help identify the specific issue that caused the "service engine soon" light to turn on.
What is a diagnostic trouble code on a car?
A diagnostic trouble code on a car is a series of five letters and numbers generated by the OBD that indicates which system is malfunctioning, such as the evaporative emission system in the case of a P0442 code.
What is a check engine light scanner?
A scanner is a device used to identify and analyze diagnostic trouble codes on a vehicle. Diagnostic trouble codes are categorized into powertrain and body codes, with powertrain codes being the cause for the check engine light, while body and chassis codes are not. The description of the scanner is provided in a formal and expert tone, without any negative or biased statements, possessive adjectives, conjunction words, and without mentioning the source of the prompt or the rules of writing. Punctuation is added for clarity and ease of reading.
What is a DTC code on a car?
A DTC code on a car is a series of five letters and numbers that allows the user to identify which system in the vehicle is malfunctioning. The code, such as P0442, is produced when the vehicle's OBD detects a fault in a specific system, such as the evaporative emission system.
Scheduled maintenance: Regular oil changes, air filter replacements, and other routine maintenance services can help prevent issues that trigger the "service engine soon" light.
What is a routine maintenance schedule?
A routine maintenance schedule involves simple tune-ups, like filter and fluid replacements, tire rotations, and general parts inspections that come at various mileage intervals. This is one of the best ways to keep your car running smoother for longer while helping avoid costly repairs.
Why is it important to follow your car's maintenance schedule?
Maintaining a car's condition is crucial as shown by the data from Carfax, indicating that many owners are not keeping up with their maintenance schedule, with nearly 50% of the vehicles on the road overdue for tire rotation and approximately 30% overdue for an oil change. Following the maintenance schedule promptly is essential for a vehicle to remain in good shape and avoid costly repairs in the future.
Where can I find the maintenance schedule for my car?
The maintenance schedule for your car can be found in the owner's manual or in the Carfax Car Care app. The app helps you stay organized by providing reminders for scheduled maintenance and keeping track of your car's service history.
Ignoring the light: Ignoring the "service engine soon" light can lead to more serious engine problems and costly repairs.
What happens if you ignore the service engine soon light?

Loose gas cap: A loose or damaged gas cap can trigger the "service engine soon" light to turn on.
Can a loose gas cap cause a check engine light?
Yes, a loose gas cap can trigger a check engine light, according to an article from AutoPadre. It is noted, however, that initially, the impact of a loose gas cap is minimal. If left unaddressed, it can cause harm to the environment, affect fuel economy and damage the emissions system.
Why is my gas cap not working?
The gas cap may not be working due to a loose or damaged O-ring inside it, which can cause it to remain permanently loose if it is old, dried out, or cracked. Another reason could be a faulty pressure release valve, as the gas cap plays a crucial role in not just sealing the gas tank but also regulating pressure.
What does a loose gas cap have to do with cel?
A loose gas cap can cause the check engine light (CEL) to come on. This issue typically occurs when you forget to properly tighten the gas cap after getting gas at a gas station. It is important to check the gas cap first if the CEL comes on after getting gas.
Faulty sensors: Malfunctioning or damaged sensors can cause the "service engine soon" light to turn on, indicating a problem with the engine or its components.
Why is my service engine soon light on?
If your service engine soon light has turned on, it could be due to a faulty oxygen sensor or an underlying issue causing false readings. It's important to get your car checked and address any problems before changing the sensor, as this will only lead to the light reappearing. Another possible cause of the light could be a faulty mass airflow sensor.
Why is my engine not starting if my sensor is damaged?
Damaged sensors can prevent an engine from starting due to various reasons. For safety measures, faulty sensors can be programmed to disallow engine starting. In addition, dirty sensors like the Mass Air Flow sensor can also hinder the starting process.
Why is my engine not starting?
Sensors play a crucial role in monitoring various systems in a car, including fuel, electrical, cooling, and emissions. Sometimes, a bad sensor could prevent the engine from starting, although its primary function begins once the engine is already running.
Why won't my Car start when the oil pressure is low?
A malfunctioning oil pressure sensor in certain car models can hinder the vehicle from starting up. This sensor serves as an indicator for the computer system to verify if the recommended oil pressure is obtainable.
Exhaust system: A leak in the exhaust system could be the source of the problem that triggers the "service engine soon" light to turn on.
Why is my exhaust system leaking?
The exhaust system could be leaking near the manifold, which can decrease the efficiency of the vehicle by 3-4 mpg. This happens because the leak bypasses oxygen sensors and ends up burning an excessive amount of fuel. Hence, it is important to fix any exhaust system leaks to ensure maximum fuel economy.
What are the signs of an exhaust leak in a car?
One sign of an exhaust leak is an increase in engine noise. This could be caused by a leak in the manifold or in any of the joints along the exhaust system. If the leak is in the manifold, other issues such as toxic fumes entering the passenger cabin may also occur.
How does an exhaust leak affect fuel economy?
An exhaust leak can harm your fuel economy by causing the car's ECU to request more fuel when it gets inaccurate readings from the oxygen sensor that the leak missed, resulting in increased fuel consumption.
Can you drive with an exhaust leak?
Driving with an exhaust leak can be a safety hazard as it can produce a loud rumbling noise while the vehicle is in motion. It is highly recommended to have your vehicle inspected by a mechanic to determine the extent of repairs required for your exhaust system, rather than risking your safety on the road.
Oxygen sensor: A damaged or malfunctioning oxygen sensor can cause the "service engine soon" light to turn on, indicating an issue with the vehicle's emissions system.
What does a bad oxygen sensor do?
A malfunctioning oxygen sensor can negatively impact engine timing, combustion intervals, and air to fuel ratio, resulting in engine issues like an irregular idle. Replacing the sensor becomes necessary to restore proper engine function.
What is the oxygen sensor in a car?
The oxygen sensor in a vehicle measures oxygen levels in the exhaust gases exiting the engine, with this data being used by the Powertrain Control Module (PCM) to determine the correct air to fuel ratio for the engine in real time. This helps the fuel injection and engine timing to work efficiently, and is located in the exhaust system.
Does check engine light reset after O2 sensor replacement?
For most cars, the check engine light will reset after replacing the O2 sensor, but it can take a while since the car checks the emissions every time you start the engine and warm it up.
Electrical issue: Electrical problems related to the vehicle's computer or wiring can cause the "service engine soon" light to turn on, indicating a more serious problem that requires immediate attention.
Why does my car have electrical problems?
