the pedal has a electronic unit that dictates throttle position.the cost is generally 300 for most cars .

p2118 means low juice battery, recharge the battery or install a new one. however your battery still good (some what) then start the car and let it idle to charge the bat.

normally when you have p2118 you won't be able to accelerate - why Throttle Actuator Control Motor Current Range is too low.
