The oxygen sensor in your Toyota RAV4 gauges the amount of unburned oxygen in your exhaust system. A defective O2 sensor will not only activate your check engine light but also negatively affect your catalytic converter, spark plugs, and fuel efficiency.
Loose, Damaged or Missing Gas Cap
A loose, broken, or missing gas cap may turn on your check engine light, making it one of the stupidest possible causes. The gas cap maintains pressure, seals the fuel system, and will lower pollutants. If a broken gas cap is left in place, hazardous emissions may rise and efficiency may suffer.
Bad Catalytic Converter
If not properly maintained, your catalytic converterwhich turns carbon monoxide into carbon dioxidecan sustain harm. If you don’t change this annoying component, you’ll have poor performance and efficiency, fail emissions tests, and operate your car at higher temperatures.
Bad Mass Airflow Sensor Needs to Be Replaced
This component detects the volume of air entering the engine of your 2016 Toyota Tacoma and calculates how much gasoline is required to run the engine effectively. Your check engine light will turn on if your airflow sensor isn’t working properly, and it can also harm your catalytic converter, O2 sensors, and spark plugs. Additionally, ratings for performance and fuel economy will suffer.
Bad Spark Plugs or Spark Plug Wires

After tightening the gas cap, will the check engine light come on?
Get out of the car and if necessary, open the gas cap door. Bring a flashlight if it is dark out. You might require the additional light to inspect the gas cap for cracks. Examine the gas cap. Are there any rips, chips, or cracks in it? If so, a straightforward gas cap replacement could be able to fix the issue.

Install the gas cap into the filler tube all the way if you are confident it is in good condition. Once you hear the gas cap click into place, tighten it with your hand. The cap has to be changed if it clicks into place but remains loose afterward.
If the check engine light was brought on by a loose gas cap, it should turn off within a few minutes of driving.
After you’ve experienced the check engine light, pay attention to the dashboard. Your gas cap is too loose if you notice that the light continues turning on and then turning off when you tighten it.
