Why is there no response when pressing the accelerator pedal to the floor on an uphill slope?

Operational issue. The original vehicle speed was slow, the gear was high, the engine torque was low, and the vehicle's inertia was insufficient, making it difficult to accelerate further. Here is some relevant information about the vehicle accelerator: 1. Function of the car accelerator: The gasoline engine's accelerator does not control the fuel injection volume but rather the throttle opening size. A smaller opening means less mixed gas enters the cylinder, resulting in lower engine power output, and vice versa. 2. Solution for a heavy accelerator pedal: You can perform a fuel system cleaning. Alternatively, try to continue accelerating to see if the engine speed increases but the vehicle speed does not. If this happens, it might be due to a damaged sensor inside the transmission locking the overdrive gear.
