P0221 - THROTTLE/PEDAL POSITION SENSOR/SWITCH B CIRCUIT RANGE/PERFORMANCE

Description:	The electronic throttle control (ETC) throttle position (TP) sensor 2 circuit was flagged as a concern 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:	This concern exhibits a symptom of limited power. A TP2 PID reading greater than 96.42% (4.65 volts) during key ON, engine OFF or key ON, engine running indicates a concern is present.
Application	Key On Engine Off	Key On Engine Running	Continuous Memory
