Can Oil Change Turn On Check Engine Light?
Oil changes are an essential part of car maintenance, but they can sometimes trigger the Check Engine Light (CEL) to turn on. This can be frustrating and confusing for car owners, especially if they are not familiar with the causes of the CEL. In this article, we will explore whether an oil change can indeed turn on the Check Engine Light and what you can do to resolve the issue.
What is the Check Engine Light?
The Check Engine Light is a warning indicator on your dashboard that illuminates when your car’s onboard computer detects a problem with the engine or emissions system. The light can be yellow or red, depending on the severity of the issue. When the CEL turns on, it’s essential to diagnose the problem as soon as possible to prevent further damage to your vehicle.
Can an Oil Change Trigger the Check Engine Light?
Yes, an oil change can sometimes trigger the Check Engine Light to turn on. There are several reasons why this might happen:
- Oil level sensor malfunction: The oil level sensor can become faulty or clogged during an oil change, causing the CEL to turn on.
- Incorrect oil type or viscosity: Using the wrong type or viscosity of oil can cause the CEL to turn on.
- Oil filter not properly installed: If the oil filter is not installed correctly, it can cause the CEL to turn on.
- Loose or damaged oil drain plug: A loose or damaged oil drain plug can cause the CEL to turn on.
- Oil change not done correctly: If the oil change is not done correctly, it can cause the CEL to turn on.
It’s essential to note that not all oil changes will trigger the CEL to turn on. However, if you notice the CEL turning on after an oil change, it’s crucial to diagnose the problem as soon as possible to prevent further damage to your vehicle. (See Also: What Causes Dirty Engine Oil)
What to Do if the Check Engine Light Turns On After an Oil Change
If the Check Engine Light turns on after an oil change, follow these steps:
Step 1: Check the Oil Level: Check the oil level to ensure it’s at the recommended level. If the level is low, add the recommended type and amount of oil.
Step 2: Check the Oil Filter: Check the oil filter to ensure it’s properly installed and not clogged. If the filter is clogged, replace it with a new one.
Step 3: Check the Oil Drain Plug: Check the oil drain plug to ensure it’s tightened properly. If it’s loose, tighten it to the recommended torque specification.
Step 4: Check for Faulty Sensors: Check the oil level sensor and other sensors to ensure they’re functioning properly. If a sensor is faulty, replace it with a new one.
Step 5: Consult a Mechanic: If the CEL remains on after checking the above, consult a mechanic to diagnose the problem. They can use a scan tool to read the trouble code and diagnose the issue. (See Also: What Color Is The Engine Oil Dipstick)
