P0221 - THROTTLE POSITION (TP2) SENSOR CIRCUIT RANGE/PERFORMANCE

Description:	The electronic throttle control (ETC) TP2 sensor was flagged as fault status by the powertrain control module (PCM) indicating an out of range in either the closed or wide open throttle (WOT) modes.
Possible Causes:	Binding throttle linkage Damaged throttle body TP circuit open to PCM Damaged TP sensor SIG RTN circuit open to the TP sensor Self-test operator error (foot resting on the accelerator pedal during test)
Diagnostic Aids:	The fault exhibits a symptom of limited power. A TP2 PID (TP V PID) reading greater than 96.42% (4.65 volts) during key on engine off (KOEO) or key on engine running (KOER) indicates a hard fault.
Application	Key On Engine Off	Key On Engine Running	Continuous Memory
