Car Engine Light On After Oil Change

If your car’s engine light comes on after an oil change, it can be a bit of a concern. After all, you just had your oil changed, so what could be wrong? There are a few reasons why this might happen, and most of them are not serious. However, it’s important to have it checked out by a mechanic to be sure.

Possible Causes

Here are some of the possible causes of an engine light coming on after an oil change:

Loose oil filter: If the oil filter is not tightened properly, it can leak oil and cause the engine light to come on.
Incorrect oil type: If the wrong type of oil is used, it can cause the engine to run less efficiently and trigger the engine light.
Low oil level: If the oil level is too low, it can cause the engine to overheat and trigger the engine light.
Faulty oil pressure sensor: The oil pressure sensor monitors the oil pressure in the engine. If the sensor is faulty, it can send a false signal to the engine computer, causing the engine light to come on.
Other engine problems: In some cases, an engine light coming on after an oil change can be a sign of another engine problem, such as a faulty spark plug or a clogged fuel injector.

What to Do

If your car’s engine light comes on after an oil change, the first thing you should do is check the oil level. If the oil level is low, add oil until it reaches the full mark on the dipstick. If the oil level is full, you should have the car checked out by a mechanic.

The mechanic will be able to diagnose the problem and make the necessary repairs. In most cases, the problem will be minor and can be fixed quickly and easily.
