Service Engine Soon light after oil change

[LanderCT7]

The service engine soon light just came on after an oil change. Car is driving perfectly and mechanic was first rate. Any thoughts? I’m trying to go somewhere and have the codes run so that the light can be reset. Any thoughts are welcome.

Did you also just put in a tank of gasoline? Try turn that gas cap a few more turns or it could be just a bad load of gasoline.

No new gasoline.

No new gasoline.

It worked!! I unscrewed the gas cap and put it back on and the light didn’t come back on. What the..? Why did that fix it?

Good! It worked for me twice over the last 3 years when I got that service engine light & re-turned the gas cap a few turns! It worked on my other Lexus RX too. The new pressure may be?
