What is the reason for the unresponsive throttle in the Tiggo 3?

The reason for the unresponsive throttle in the Tiggo 3 is: a malfunction in the vehicle's power system. The engine power is achieved through the coordinated operation of the intake system, ignition system, and fuel system. Taking the 2020 Tiggo 3 as an example, its body dimensions are: length 4420mm, width 1760mm, height 1670mm, wheelbase 2510mm, minimum ground clearance 190mm, and fuel tank capacity 55l. The 2020 Tiggo 3 is equipped with a 1.5l naturally aspirated engine, with a maximum power of 85kw and a maximum torque of 143nm, paired with a 5-speed manual transmission.
I also experienced an unresponsive throttle issue when driving my Tiggo 3 before—it felt like stepping on a brick. This is most likely an accelerator pedal problem, such as a dirty or faulty sensor. You should thoroughly check its connection. Another possibility is a stuck throttle valve; if not cleaned regularly, carbon buildup can block airflow, naturally making the throttle sluggish. A common culprit could also be minor electrical issues, like a blown fuse—check the fuse box under the driver’s seat (don’t worry, it’s simple; just ask a car-savvy friend to take a look). The fuel system might also be to blame—if the fuel pump isn’t delivering fuel or the injectors are clogged, the car loses all power. In my case, it was a faulty fuel injector; replacing it fixed the issue. I recommend cleaning the fuel system during regular maintenance—don’t wait for a major breakdown to act. It saves money and keeps you safe.
Speaking of throttle failure, I think many cases are related to electronic control. The ECU module of the Tiggo 3 is crucial. If it malfunctions or gets short-circuited due to water ingress, the pedal signal won't reach the engine, and the throttle naturally fails. I've encountered similar issues before, such as a faulty position sensor—the position sensor is located behind the pedal and can wear out or accumulate dust over time, leading to signal interruption. Also, check the ignition system; if the spark plugs fail to ignite, the car won't respond, especially noticeable at high speeds. Don't overlook the fuses—they're small and easy to miss, but once they blow, it's game over. I once accidentally tampered with the wiring while modifying the audio system, resulting in throttle failure, so sticking to factory settings is more reliable. Regular diagnostic scans with a computer can be a big help.
