Why Is My Lexus Check Engine Light Illuminated?

Lexus of Santa Fe welcomes you to discover why your Lexus check engine light is illuminated.

The check engine warning light warns drivers of possible engine issues or even complete failure. Your car’s check engine warning light might turn on due to many reasons. It may be small things like sensor failure, alerting you to schedule preventive maintenance, or even to be looking for potentially significant issues that might cause engine failure. So, even if the check engine warning light turns on, it may not be a complete catastrophe. However, when your check engine light comes on, we suggest bringing it to us for a thorough inspection as soon as possible. Even if nothing seems broken, getting it inspected can mean the difference between a simple fix and having to replace the engine.


Failing Gas Cap

The Gas Cap is Failing

Something as silly as not replacing the gas cap or not tightening it correctly can trigger a check engine light. Your vehicle’s gas cap may need to be changed during your time of ownership. Gas caps may have a life expectancy as low as 50k miles. If it is time to replace your gas cap, we suggest genuine OEM replacement parts. Parts from DIY stores can work in a pinch, but nothing is better than OEM parts.

Old Vehicle O2 Sensors

Oxygen Sensors in The Vehicle are Bad

There are several sensors that feed info to the engine to help it run efficiently. However, missing sensor readings from components like the MAF sensor or the oxygen sensors can cause a check engine warning light. If your vehicle is running like normal, a broken oxygen sensor is the likely reason. This could mean your car is running normally, but since the engine isn’t getting the data, it triggers a warning. Even if your car feels normal, you should get it diagnosed ASAP to rule out larger issues.

Bad Spark Plugs

Faulty Spark Plugs

Spark plugs are essential to the performance of your engine. As the name indicates, spark plugs give off a small spark of electricity that ignites the fuel and causes your engine to run. Spark plugs require accurate tolerances for peak performance, and if the spark plug gap is too small, it could possibly trigger a check engine warning light. Symptoms of worn spark plugs include diminished fuel efficiency, less engine power, and your engine just doesn’t run smoothly.
