The Throttle Position sensor signals the Engine Control Module as to the current position of the engine throttle valve.
The current throttle valve opening is based on the driver's input from the gas pedal. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.
Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code C0458, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code C0458 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
If your seat recline forward/backward potentiometer feedback circuit open check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system C0458 and engine control unit are in charge of monitoring a bunch of different seat recline forward/backward potentiometer feedback circuit open, and if they get a reading that's a little out of whack, up pops the check engine light.
