P2119 Throttle Actuator Control Throttle Body Range/Performance

P2119 means the throttle body is not returning to, or holding, its expected rest/limp position — the throttle-plate behaviour is outside the range the module expects when it is not being driven.

Code details

Generic OBD-II · P2

System: Speed / Idle
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not force-clean or lubricate an electronic throttle body incorrectly; follow the relearn procedure after cleaning so the module recalibrates the stop.

Symptoms of P2119

Reduced-power mode or a warning light.
High, low, or hunting idle.
Hesitation or poor throttle response.

Common causes of P2119

Carbon build-up sticking the throttle plate.
A weak or broken throttle return spring.
A failing throttle-actuator assembly.
A calibration/relearn not performed after service.

Useful checks before replacing parts

Clean and inspect the throttle body for carbon and a sticking plate.
Check the return-spring behaviour and default (limp) position.
Confirm throttle-position feedback tracks the plate correctly.
