What Causes the Throttle to Fail After a Vehicle Drives Through Water?

[StevenDella]

Reasons for throttle failure after a vehicle drives through water: Fuel line blockage: When the vehicle's fuel system is blocked, especially if the fuel injectors are clogged, fuel cannot be adequately transported, leading to incomplete combustion in the engine cylinders. As a result, the engine's power decreases, causing the vehicle to not accelerate when the throttle is pressed. Exhaust system malfunction: Exhaust system issues, typically involving a clogged catalytic converter or exhaust pipe, can also prevent the throttle from functioning properly. Throttle body carbon buildup: When a vehicle has been driven for an extended period without cleaning, carbon deposits can accumulate on the engine's throttle body, affecting fuel combustion and ultimately leading to reduced vehicle power and increased fuel consumption.
