Why Does My Chevy Malibu Say Engine Power Reduced?

I was driving my 2015 Chevy Malibu the other day when suddenly, the “Engine Power Reduced” light came on and the car started losing power. I was in the middle of nowhere, and I was starting to get worried. Thankfully, I was able to limp the car to a nearby mechanic, who told me that the problem was with the throttle body. Luckily, the repair was relatively inexpensive, and I was back on the road in no time.

Throttle Body: The Culprit Behind Reduced Engine Power

The throttle body is a key component of your car’s engine. It controls the amount of air that enters the engine, which in turn affects the amount of power the engine produces. When the throttle body becomes dirty or clogged, it can restrict the flow of air into the engine, causing a loss of power. In some cases, the throttle body may even become completely stuck, which can cause the engine to stall.

Symptoms of a Bad Throttle Body

• Engine power reduced message: When the throttle body is not working properly, the car’s computer may display a “engine power reduced” or “throttle body service” message.
• Loss of power: If the throttle body is restricting the flow of air into the engine, it will cause the car to lose power. This may be most noticeable when accelerating or climbing hills.
• Rough idle: A bad throttle body can also cause the car to idle roughly or even stall.
• Check engine light: If the throttle body is malfunctioning, the car’s check engine light may come on.

Diagnosing a Throttle Body Problem

If you are experiencing any of the symptoms listed above, it’s important to have your car diagnosed by a qualified mechanic. The mechanic will be able to use a diagnostic scanner to check for trouble codes that may be related to the throttle body. The mechanic may also perform a physical inspection of the throttle body to look for signs of damage or debris.

Repairing a Throttle Body

In most cases, a bad throttle body can be repaired by cleaning or replacing it. If the throttle body is simply dirty, cleaning it with a throttle body cleaner may be sufficient. If the throttle body is damaged or worn, it will need to be replaced. The cost of repairing or replacing a throttle body will vary depending on the make and model of your car.
