What is the reason why the old Cruze cannot accelerate when stepping on the gas pedal?

The reason why the old Cruze cannot accelerate when stepping on the gas pedal may be due to prolonged use of the car, resulting in throttle blockage. It is recommended to promptly visit a repair station for inspection and maintenance. Below is a detailed introduction about the Cruze car: 1. Overview: The Chevrolet Cruze is a new-generation model developed by General Motors with the goal of creating a benchmark in design and performance for compact cars, integrating global resources. 2. Others: The most noticeable change in the appearance of the new Cruze is the alteration of the rear badge, using "330T" and "320" to distinguish between models equipped with the 1.4T turbocharged engine and the 1.5L engine, respectively.
I've driven an older model Cruze and experienced the issue of no response when stepping on the accelerator. It's mostly likely a problem with the throttle position sensor, as these components tend to malfunction or experience signal drift when they age. Severe carbon buildup in the throttle body is another common cause. Over time, carbon deposits accumulate in the valve ports, restricting airflow, so when you press the accelerator, no air enters the engine, naturally preventing acceleration. The fuel pump could also be underperforming, leading to insufficient fuel supply, especially when starting after being parked for several days. I recommend not pushing through it—for safety, pull over and check, then promptly visit a professional shop to read the fault codes with a diagnostic tool. Replacing the parts usually solves the issue. Regularly cleaning the throttle body and replacing the air filter can help prevent these troubles.
Having repaired many Cruze models, I believe the key issue with the old version's throttle not accelerating lies in the electronic system. When the throttle pedal sensor ages and detects inaccurately, the ECU (Engine Control Unit) fails to receive precise signals and thus doesn't increase fuel delivery. A dirty or stuck throttle body or a faulty mass airflow sensor can also frequently cause problems. On the fuel side, a broken fuel pump or clogged fuel injectors can disrupt smooth fuel supply. My personal diagnostic routine starts with checking if the throttle pedal feels loose, listening to the engine sound for smoothness during ignition, and checking the dashboard for any warning lights. Often, replacing small components can fix the issue, but the electronic control system is complex—avoid DIY modifications and consult a technician with proper diagnostic tools. If you encounter this issue while driving, slow down and stop safely; safety comes first.
