P2119 – Throttle Actuator Control Throttle Body Range/Performance
Encountering the P2119 code in your Chery? Here is a complete guide to its causes, symptoms, and solutions.
What Does Code P2119 Mean
The P2119 code is related to the throttle actuator control throttle body range/performance. This code indicates that the engine control module (ECM) has detected a problem with the throttle actuator or throttle body, which is responsible for regulating the airflow into the engine. The throttle actuator is a critical component that helps to control the engine’s speed and performance. When the ECM detects a malfunction in the throttle actuator or throttle body, it will trigger the P2119 code and store it in the vehicle’s onboard diagnostics system.
Common Chery Models Affected
- Chery Tiggo 5
- Chery Arrizo 7
- Chery Fulwin 2
- Chery QQ
- Chery Cowin 3
Symptoms
- Poor engine performance, such as hesitation or stumbling
- Decreased fuel efficiency
- Difficulty starting the engine
- Idle instability or rough idling
- Loss of power or acceleration
- Check Engine Light illumination
- Erratic throttle response
Causes Table
| Potential Cause | Probability (High/Medium/Low) |
|---|---|
| Faulty throttle actuator | High |
| Dirty or clogged throttle body | Medium |
| Electrical issues, such as faulty wiring or connectors | Medium |
| Software problems or outdated ECM calibration | Low |
| Failed throttle position sensor | Medium |
| Corrosion or damage to the throttle actuator or throttle body | Low |
Diagnostic Steps
To diagnose the P2119 code, a technician will typically start by scanning the vehicle’s onboard diagnostics system to retrieve any stored trouble codes. They will then use a scan tool to monitor the throttle actuator and throttle body performance, checking for any irregularities or malfunctions. The technician will also inspect the electrical connections and wiring related to the throttle actuator and throttle body, looking for any signs of damage or corrosion. Additionally, they will check the throttle position sensor and its circuit to ensure it is functioning correctly. The readings should change smoothly depending on engine RPM, and any irregularities can indicate a problem with the throttle actuator or throttle body.
How to Fix
The primary repair method for the P2119 code is to replace the faulty throttle actuator or throttle body. In some cases, cleaning or repairing the throttle body may be sufficient. If the issue is related to electrical problems, the technician will need to repair or replace the faulty wiring or connectors. If the problem is software-related, the ECM may need to be updated or reprogrammed. In any case, it is essential to follow the manufacturer’s recommended repair procedures to ensure the issue is resolved correctly.
Is It Safe to Drive with This Code
Driving with the P2119 code can be risky, as it can lead to decreased engine performance, poor fuel efficiency, and potentially cause damage to other engine components. Additionally, the code can cause the engine to stall or hesitate, which can increase the risk of an accident. It is recommended to have the issue diagnosed and repaired as soon as possible to avoid any further problems.
Estimated Repair Cost
The estimated repair cost for the P2119 code can range from $200 to $1,000, depending on the specific cause of the issue and the type of repair required. If the throttle actuator or throttle body needs to be replaced, the cost can be higher. Additionally, if the issue is related to electrical problems or software issues, the cost can be lower.
Preventive Maintenance Tips
To prevent the P2119 code from occurring, it is essential to follow regular maintenance schedules, such as cleaning the throttle body and checking the electrical connections. Additionally, using high-quality fuel and avoiding extreme driving conditions can help to reduce the risk of engine problems. Regularly scanning the vehicle’s onboard diagnostics system can also help to identify any potential issues before they become major problems.
