How to solve the heavy throttle issue of BYD F0?
2 Answers
BYD F0 heavy throttle can be resolved by cleaning the throttle body or replacing the throttle cable. The throttle, a device on an internal combustion engine that controls the fuel supply, is generally controlled by a pedal in car engines, also known as the accelerator pedal, which is the device that controls the fuel supply to the engine. Additional information: 1. For manual transmission models where the throttle cannot return to its position, immediately press the clutch and shift the gear lever to the neutral position. This action is equivalent to the engine revving without transmitting power to the wheels. Then, you can slowly stop the car by the roadside as you normally would when braking, turn off the engine, and check the throttle pedal. If it is not stuck by foreign objects or floor mats but the throttle itself is stiff or stuck, do not continue driving. 2. For automatic transmission models, try to press the brake pedal. If the throttle is not stuck too deeply, forcing the brake can generally reduce the car's speed to a very low level, and then you can shift the gear lever to the N (neutral) position and pull over to stop.
Having driven a BYD F0 for several years, I've encountered the issue of a heavy throttle a few times. It's mostly caused by insufficient lubrication or aging of the throttle cable. You can check it yourself first: open the engine hood, locate the throttle cable, and spray some lubricant like WD-40 to let it soak in. The throttle pedal spring might be loose or rusty—try stepping on it to see if there's any sticking sensation. For electronic throttle models, like the newer F0, heavy carbon buildup on the throttle body can also make it stiff; just buy some throttle body cleaner and spray it. Don’t overlook safety—a sluggish throttle can lead to unintended acceleration while driving, which is quite dangerous. It’s best to have a technician lubricate the related components during regular maintenance to prevent recurrence. If the issue persists, take it to a 4S shop early to avoid minor problems turning into major repairs. Remember, these small steps can extend your car’s lifespan.
