Throttle Actuator Control Range/Performance
The P2119 code indicates that the Engine Control Module (ECM) has detected a malfunction in the throttle actuator control system, specifically that the throttle body is not responding within the expected range or performance parameters. This can be caused by a faulty throttle body, carbon buildup, wiring issues, or a failed throttle position sensor. The system uses an electronic throttle control motor to open and close the throttle plate based on accelerator pedal input; when the actual position does not match the commanded position, the code sets.
1. Most Common Causes
- Faulty throttle body assembly
- Carbon buildup on throttle plate
- Wiring or connector issues in throttle actuator circuit
- Failed throttle position sensor
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Reduced engine power or limp mode
- Poor acceleration or hesitation
- Rough idle or stalling
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect throttle body for carbon buildup and wiring for damage.
Step 3: Test throttle actuator motor and throttle position sensor with a multimeter.
Step 4: Perform throttle body relearn procedure after cleaning or replacement.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with P2119 as it can cause sudden loss of power or stalling, leading to unsafe driving conditions.
How much does it cost to fix?▼
The cost to fix P2119 typically ranges from $50 to $150 for cleaning or sensor replacement, but a full throttle body replacement can cost $200-$500.
