I have a 2004 Lexus ES 330, and I started receiving Check Engine Code P2122. My code reader lists it as: Throttle / Pedal Position Sensor / Switch D Circuit Low. The car doesn't respond nearly as well when you press the gas pedal down now, and obviously isn't safe to drive. Not sure where to go from here. I'm not familiar with working on Lexus / Toyota cars. Any recommendations would be great.
