How do I adjust the idle speed on my electronic throttle body?

Disconnect the idle air adjustment valve by locating and disengaging the electronic connector that holds it to the throttle body. Turn the idle screw to adjust the idle—turn the screw to the left to increase the RPM or to the right to lower it.

How do you fix high idle after cleaning throttle body?

Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel. The idle will relearn if you put the vehicle in drive and allow the idle to come down with all accessories off for about two to three minutes.

What does a red lightning bolt on the dash mean?

Can I drive with the throttle control warning light on?

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.

What are the symptoms of a dirty throttle body?

When the throttle body gets dirty, it has a direct effect on how smoothly the engine operates. Signs indicating a problem include rough idling, jumpy or sluggish acceleration, poor fuel economy, and stalling. With the use of a throttle body cleaning product, the dirt and debris buildup are easily removed.

What happens if TPS is not calibrated?

If your TPS is faulty or uncalibrated, the sensor will be unable to accurately determine the position of the sensor. This will lead to a variety of symptoms, all of which are caused by the fact that the ECM is delivering the wrong air/fuel ratio to the cylinders thanks to the bad sensor.

Common signs include lacking power when accelerating, rough or slow idle, stalling, inability to shift up, and the Check Engine Light coming on.

What causes high rpm at idle?

The most common problem is a faulty fuse. In modern vehicles, engine idle speed is most often controlled by the idle air control (IAC) motor. This can be impacted by bad fuses in many different electronic systems in your car. Next, your high idling could be caused by a computer malfunction.
