WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
P0121 - ETC THROTTLE POSITION (TP1) SENSOR CIRCUIT RANGE/PERFORMANCE

Description:  The electronic throttle control (ETC) TP1 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: 
  • Obstruction in the throttle plate movement.
  • Damaged throttle body.
  • TP circuit open to PCM.
  • SIG RTN circuit open to the TP sensor.
  • TP sensor faulty or damaged.
  • Damaged PCM.
Diagnostic Aids:  The fault exhibits a symptom of limited power. A TP1 PID (TP V PID) reading less than 13% (0.65 volt), or greater than 93% (4.65 volts) during KOEO or KOER indicates a hard fault.
