My 2007 toyota corrolla s-type has a throttle

Throttle Actuator Control Motor Current Range/Performance

http://www.autocodes.com/p2118_toyota.html

First thing to check is fuses, then the brake pedal "Kick Out" switch that can often come loose or out of adjustment, next relay, next actuator.

-If it is. Take it out , disassembly and clean it. Then put it back

to find out how it work. If not the possibly need to buy new one.

Here go to this web site (www.rockauto.com) . Possibly it'll be less then what the dealer told you.

Good Luck

Description

Engine control module (ECM) - throttle actuator control (TAC) system - malfunction


Cause

ECM

P2118 Toyota Description
The Electronic Throttle Control System (ETCS) has a dedicated power supply circuit. The voltage (+BM) is monitored and when the voltage is low (less than 4 V), the Engine Control Module (ECM) concludes that the ETCS has a fault and current to the throttle actuator is cut. When the voltage becomes unstable, the ETCS itself becomes unstable. For this reason, when the voltage is low, the current to the actuator is cut. If repairs are made and the system has returned to normal, turn the ignition switch OFF. The ECM then allows current to flow to the actuator and actuator can be restarted.

Possible causes
- Faulty Throttle Actuator Control Actuator
- Electronic Throttle Control System (ETCS) harness is open or shorted
- Electronic Throttle Control System (ETCS) circuit poor electrical connection

Have you tested/looked into the throttle actuator control relay or module for issues? Both are located on the pass side.......so if the ac drain/filter got clogged and allowed water onto those there could be an issue with them. Also check your connections at the throttle body.

a suzuki toyota. , id love to see that...
08 toy my guess.
what is throttle?
what is low.
why not, post symptoms
and scan codes (DTCs actual)
and 1st check all fuses.
is this a throttle by Wire question, do say so..

This indicates an internal failure of the throttle actuator control unit. How many miles on this vehicle? If it is under 100k, it could be covered by GM powertrain warranty.

Your vehicle is equipped with "fly by wire" throttle. When you step on the accelerator, you are actually stepping on a variable resistor that changes voltage in a circuit that goes to the throttle actuator module mounted on the throttle body on the engine. In plain english: your throttle is computer controlled. If this system is not working correctly, there should be fault codes stored in your engine computer.
