Throttle Actuator Control Range/Performance
The P2119 code indicates that the Powertrain Control Module (PCM) has detected a malfunction in the throttle actuator control system, specifically that the throttle body is not responding correctly to commands. This can be due to mechanical binding, electrical issues, or carbon buildup preventing proper throttle plate movement.
01. Most Common Causes
- Carbon buildup on throttle body
- Faulty throttle actuator motor
- Wiring or connector issues
- Failed PCM
02. Symptoms You Will Notice
- Check Engine Light on
- Reduced engine power or limp mode
- Poor acceleration or hesitation
- Rough idle or stalling
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect throttle body for carbon buildup and clean if necessary.
Step 3: Test throttle actuator motor and wiring with a multimeter.
Step 4: Perform throttle body relearn procedure after repairs.
