The Engine Control Module of your vehicle monitors the functioning of all the systems. When it finds a fault in the rate of flow of the EGR system vent control circuit, it will set the P2145 code and the check engine light may also get illuminated. The ECM module uses electrical solenoids which allow engine vacuum when open and restrict vacuum to the EGR valve when they’re closed. Depending on the degree of voltage the valve will open and close. When the valve registers a high voltage even when the EGR control solenoid is on, the ECM will note it as a problem with the EGR control solenoid valve system, and will not hesitate to set the OBD code.


What causes this problem with the Exhaust Gas Recirculation Vent Control Circuit High?

Easy Diagnosis Of Engine Error OBD Code P2145

Here are some steps which you should follow in order to diagnose this fault code P2145:


Start off by researching the Technical Service Bulletins (TSB) of your vehicle. For advanced diagnosis you will require some tools and also information. You can follow the steps before to fix this code:


The EGR systems are hot by nature as they are connected directly to the exhaust system, so before you begin your diagnosis by ensuring that your vehicle has cooled down completely. If the engine hasn’t cooled down completely you may burn yourself during diagnosis. So don’t skip this step for safety reasons. The EGR valves are mounted on the exhaust and the vent solenoids controlling the EGR venting are present anywhere in the engine bay, usually they’re on the firewall. All the burnt and broken vacuum lines should be repaired or replaced as per need. The rubber vacuum lines running from the vent solenoid to the EGR system should also be replaced as usually if one is damaged the others ones will soon be damaged too.


Now check the harnesses, ensure they’re all in good working condition, and aren’t loose or not coming in the way of other components. All the harnesses that are showing signs of corrosion, or are burned will have to be repaired or replaced as per the extent of damage. Move on to inspecting the vent solenoid for any water intrusion or damages such as cracks. Also check connectors for damages and see if they're making a proper electrical connection. You can also check the EGR valve for any issues and use a carburetor cleaner and a toothbrush to clean the soot from areas where it’s more difficult to clean.


Common Mistakes When Diagnosing The P2145 Code


  • Replacing the EGR valve hastily before checking its components for fault
  • Replacing the EGR valve when the issue is with the circuitry and other electrical parts
