This system controls the throttle body, which regulates the amount of air entering the engine. If there’s an issue with this system, your Chevy Cruze may not accelerate properly, resulting in reduced engine power.
Sensor Issues
Another potential cause of reduced engine power is a faulty sensor. Sensors like the oxygen sensor, throttle position sensor, and mass airflow sensor can malfunction, causing the engine to run poorly. This can trigger the “Engine Power is Reduced” message to appear.
Fuel System Problems
If there’s a problem with the fuel system, your Chevy Cruze may not be receiving enough fuel, causing reduced engine power. A faulty high-pressure fuel pump or a clogged fuel filter can be the reason behind this issue.
Throttle Body Problems
The throttle body is responsible for regulating the amount of air that enters the engine. If it’s not functioning correctly, your Chevy Cruze may not accelerate properly, resulting in reduced engine power. A dirty or faulty throttle body can cause this problem.
Air Filters
