Faulty Throttle Position Sensor (TPS): A malfunctioning TPS can provide incorrect signals to the engine's computer, leading to unintended acceleration.
Cruise Control problems: A faulty cruise control system or a stuck accelerator cable could cause the car to accelerate on its own.
Vacuum Leaks: A vacuum leak can cause the engine to receive less air than intended, leading to a richer fuel mixture and potentially causing the car to accelerate unintentionally.
Faulty Engine Control Module (ECM): The ECM is responsible for managing various engine functions. If it malfunctions, it can send incorrect signals to the throttle body, resulting in unintended acceleration.
Floor Mat Interference: In rare cases, an improperly placed floor mat could interfere with the accelerator pedal, causing the car to accelerate when unintended.
Stuck accelerator pedal: It is possible that the accelerator pedal itself may become stuck or have a mechanical issue that prevents it from returning to its original position, causing unintended acceleration.
If you experience unintended acceleration in your Honda Civic, it's crucial to seek immediate assistance from a qualified mechanic or visit an authorized Honda dealership. They can properly diagnose the issue and take appropriate corrective actions to ensure your vehicle's safety.
