P2119Throttle Actuator A Control Throttle Body Range/Performance

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
This is a mechanical performance check of the electronic throttle body. GM calls it Throttle Closed Position Performance: after the motor is de-energized the return springs must bring the plate into its default (limp) position, e.g. 1.32-1.90 V on TP sensor 1 in GM's 2006 tables; 15 failed samples in a row set it. A Bosch-based GM ECM times the spring return at key-on (fault above 0.56 s). Toyota, Lexus, Ford (Ranger/Bronco, ice behind the throttle) and Mitsubishi use the code too. Unlike P2101 (position error while driven) or P2118 (motor current), P2119 points at a sticking or iced plate or a weak spring; the engine may enter limp mode.
What you may notice
  • Engine warning lamp on
  • Reduced power or limp mode
  • Hesitation or uneven acceleration
  • Raised or unstable idle
Likely causes
  • LikelyCarbon deposits make the throttle plate stick
  • PossibleWater or ice in the intake behind the throttle body
  • PossibleWeak return spring or worn gear in the throttle body
  • RareECM software that sets the code falsely (update available)
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
