P2119
Throttle Actuator A Control Throttle Body Range/Performance
Throttle / air metering
Generic OBD-II
High
What it means
P2119 means the electronic throttle body isn't opening or closing the way the ECM commands — the actual throttle position is out of its expected range. Because the computer controls the throttle directly, it often responds by cutting power and entering a limp mode. The usual culprits are carbon buildup in the throttle bore or a failing throttle body, rather than the engine itself.
High
Can I keep driving? Often forces a reduced-power limp mode with sharply limited acceleration — drive gently and get it repaired promptly, as merging and climbing can be unsafe.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced power / forced limp (failsafe) mode
- Rough, surging, or unstable idle
- Poor or delayed throttle response
- Occasional hard starting or stalling
Common causes
Most likely first
- Carbon-filled or dirty throttle bore restricting the throttle plateLikely
- Faulty throttle body / throttle actuator or its position sensorCommon
- Open or shorted wiring in the throttle body circuitCommon
- Poor or corroded connector at the throttle bodyLess often
- Faulty engine control module (ECM) — rareLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data, then inspect and clean the throttle bore and plate — carbon buildup is the most common cause of a range/performance fault.
- Check the throttle body connector for a steady 5-volt reference and a good ground, key on.
- Inspect the wiring and connector for damage, corrosion, or loose pins.
- If the actuator or its feedback is still out of range, replace the throttle body and perform the throttle relearn.
FAQ
Quick answers
Is it safe to drive with P2119?+
Only cautiously and briefly. This code commonly triggers limp mode with severely reduced power, which makes merging and hill climbs risky — get it fixed promptly.
Can I just clear P2119?+
Clearing it won't help if the throttle body is dirty or failing; the code returns quickly. Cleaning the throttle and relearning idle is often what actually resolves it.
