Modern engines, particularly those equipped with emission management technologies like Exhaust Gas Recirculation (EGR) systems, are sensitive to even the smallest failures of their components. One common issue with these engines is related to the throttle actuator in the exhaust system, which plays a crucial role in managing exhaust gas flow and regulating emissions. When encountering fault codes like “low current,” “cut wire,” or “high resistance,” it indicates a malfunction in the actuator’s electrical system, affecting the engine’s performance and exhaust system efficiency.
In this section, we will thoroughly examine this technical issue and how Jaltest INFO Web can provide a complete solution by guiding you through the entire diagnostic and repair process.
Symptoms of the Fault: The fault codes associated with a throttle actuator issue can present in various ways, including:
- The engine does not start or has irregular performance.
- The exhaust system does not properly regulate gases, leading to a loss of power or excessive emissions.
- Dashboard alerts related to exhaust gas sensors.
Common Causes of the Problem:
- Wire cut or poor connection: One of the wires connecting the actuator to the ECU may be cut or have a faulty connection, leading to a loss of signal or insufficient current.
- High resistance: This can indicate that the actuator or one of its associated sensors has abnormal resistance, affecting the engine and exhaust system’s proper functioning.
- Electrical power issues: A failure in the power supply to the actuator can result in system failure.

Repair Steps with Jaltest INFO Web:
1️⃣ Read the Fault Codes
Log in to the Jaltest INFO Web platform and open the fault code reading tab. The system will provide detailed information about the error code detected. In this case, the code should refer to an issue with low current or high resistance on the throttle actuator.
- Analysis of Electrical Diagrams
Thanks to the detailed electrical diagrams available on Jaltest INFO Web, you can visualize the entire wiring of the actuator system. This view allows you to spot potential wire cuts, corroded connectors, or short circuits in the electrical circuits.
- Repair and Component Replacement
Based on the test results, here are the possible actions:
- Wiring: If a wire is cut or improperly connected, repair or replace the faulty wire.
- Connectors: If the connectors are corroded or damaged, clean or replace them.
- Sensor or Actuator: If the resistance is too high in the sensor or actuator, replacement is likely necessary.
- Resetting Fault Codes
After completing the necessary repairs, reset the fault codes using Jaltest INFO Web. This will allow you to verify if the issue has been resolved and if the actuator is functioning correctly.
A fault related to the exhaust gas throttle actuator may seem complex, but with Jaltest INFO Web, you have access to a quick and effective diagnostic and repair solution. With powerful tools like fault code reading, detailed electrical diagrams, component testing, and code resetting, this platform guides you step by step to resolve the issue and ensure optimal engine and exhaust system performance.
