Common Reasons For Check Engine Light After Oil Change
If your check engine light is on after an oil change, don’t worry. It’s a common problem. Perhaps there are some medical problems in your vehicle or at the oil change. Knowing why it occurred can help you fix it and get back on the road quickly.
Loose or Damaged Oil Cap
A loose or damaged oil cap is a common cause. The cap might not have been tightened right during the oil change.
This lets air into the engine and turns on the warning light. Check the oil cap and make sure it’s tight.
Oil Pressure Sensor Issues
The oil pressure gauge monitors your engine’s oil pressure. If it finds something strange, it will turn on the check engine light. That could be a sign that your oil system needs service.
Incorrect Oil Level
If you apply too much or too little oil, the light will also come on. Check your car’s oil level just right. Oil changes are your number one way to keep your car in good shape.
If it does not dim even after you do these things, it’s time to see a mechanic. They can deep dive and find the real cause. Repairing it soon prevents further injury and keeps your car a running piece of business.
Understanding Engine Warning Lights And Their Significance
If you’re a driver, you’ve probably witnessed the check engine light during an oil change. These are your car’s health indicators.
They alert you to problems. Knowing what they refer to can help you address things before they worsen.
Engine warning lights are usually filled with problems, from a leaky gas cap to a very bad sensor.
If your check engine light is coming on, you need to know why so that you don’t have bigger issues and more expensive repairs.
It’s vital to watch your car’s dashboard lights, especially after an oil change or regular maintenance.
By understanding these lights, you can catch problems early. This keeps your car running well and saves you money on repairs.
Immediate Steps When Your Check Engine Light Appears Post-Oil Change
Be fast when your check engine light comes on during an oil change. As a car lover, you have some things to look into. Get the proper mechanic’s help and learn how to troubleshoot this.
Safety Precautions To Take
We care about your security the most. Stop if the lights come on with weird sounds, smoke, or a big loss of power. Reverse the engine and dial 911. Continue driving will damage your car more.
Basic Diagnostic Checks
When you are safely stopped, perform some routine checks. Check the oil level, check for leaks, and ensure the oil cap is tight. These can demonstrate whether the oil change caused the problem.
When To Stop Driving?
If the light stays on or you notice other omens, don’t drive. It’s better to leave it until the issue is solved. Driving on might make things worse and be very expensive to fix. The professional mechanic is the one to ask.
Professional vs DIY Oil Changes: Avoiding Common Mistakes
Expert oil change services or DIY can be hard to decide. It’s a compromise between easy, expensive, and good.
Your DIY oil change will save you money but also comes with the potential of making an error that might trigger your check engine light.
One of the big pitfalls of performing DIY oil changes is getting the oil levels wrong. Too much or too little oil will damage the pressure sensor and trigger the check engine light.
Trust the professional mechanics to find the right oil for your vehicle, and don’t make this mistake.
What about the type of oil and filters you’re using? Aimless oil and filters with the wrong brands will compromise your engine’s health and life.
A professional oil change service uses the most appropriate brand-name products to keep your car running.
It’s a bit cheaper to make your own oil changes, but there’s the danger: the tools you need are there, and you must remove your old oil.
These are things most people don’t want to be associated with, such as a professional car repair service.
Prompt, professional, preventive maintenance will eliminate the check engine light and keep your vehicle dependable for years.
