Take a look at your throttle body and ensure that it can easily open and close. If it can’t, see if you can’t remove any obstructions and try cleaning it with a high-quality carb cleaner. If that still doesn’t work, you might need to replace the throttle body.

Is It Safe To Drive With an Electronic Throttle Control Light?

It is not safe to drive with an electronic throttle control light. While you might be lucky and only have a drop in fuel efficiency or a slight drop in acceleration, the problem can quickly get worse if the sensor readings continue to go awry.

The throttle body controls how much air enters the engine, and if your vehicle’s ECM can’t keep accurate tabs on this, then it can quickly lead to an out-of-control engine. If you have an electronic throttle light that’s on, you can quickly damage your engine, which can lead to even more expensive repairs when you get it to a repair shop.

This is true even if you don’t notice significant drops in your throttle response or vehicle performance. That’s because the air to fuel ratio isn’t what it should be, which can lead to premature engine wear over time.

Summary

While you might feel that everything is getting more complicated in modern vehicles, these complicated features have huge benefits. Not only do you get better fuel economy, but you get a more powerful and a more responsive engine.
