2004 Toyota Tacoma V6 3.4L with automatic transmission. Toyota originally equipped this vehicle with a throttle by wire system. The vehicle unexpectedly does not respond to accelerator pedal position. Toyota on board diagnostic system does not detect fault thus does not log any error codes or illuminate check engine light. Occurrence rate and duration of events is intermittent and inconsistent. Velocity of the vehicle rapidly decreases unexpectedly and momentarily as if foot was temporarily removed from the accelerator pedal. Vehicle also unexpectedly and momentarily does not respond when accelerator pedal is depressed to begin moving or suddenly decreases speed when accelerating.
This is a potential hazard in situations such as cruising in traffic, clearing an intersection, crossing railroad tracks, etc... occurrence rate and duration of problem seems to be worsening over time or with increased ambient temperatures. It's been determined that the Accelerator Pedal Position Sensor is bad. Toyota will only sell the part with the complete throttle body $500. No aftermarket support either.
