Chevrolet Tracker EGR Vacuum Solenoid Parts Questions & Answers
- Q: What is the purpose of the EGR Vacuum Solenoid and EGR Valve?A: The Exhaust Gas Recirculation (EGR) system reduces nitrogen oxides by recirculating exhaust gas into the intake manifold. The EGR valve, controlled by a modulator, adjusts based on load conditions. California fuel-injected vehicles also have a sub-EGR valve managed by a PCM-controlled Vacuum Switching Valve (VSV). To inspect the system, ensure the EGR valve diaphragm moves when the engine is cold and warm. Use a vacuum pump to test the valve if unresponsive. Examine hoses for damage and replace if needed. Test the EGR modulator and BVSV for vacuum retention. Check the TWSV or VSV for airflow. For 1999+ models, verify the EGR valve's resistance. To replace, disconnect and remove the old component, clean surfaces, and install the new part.
