If you are experiencing a PO455 error code in your vehicle, don’t worry, as there are practical solutions that you can implement at home to fix the issue. In this article, we will walk you through two DIY methods to troubleshoot and resolve the PO455 error code.
Use the Zeus App to Scan Your Vehicle
Before you start with the solutions, use the Zeus app to scan your vehicle and identify the error code PO455. This code indicates that the evaporative emission system has detected a gross leak, typically greater than 0.04 inches in diameter.
Method A: The Gas Cap
Begin by opening your gas tank and examining the condition of the gas cap. Use a WD-40 cleaner to spray and clean the gas tank, and check if the gas cap is dirty. If so, use the cleaner to wipe it clean. If the cap is in poor condition, consider replacing it with the correct model gas cap.
Method B: The Canister Purge Valve
The canister purge valve is typically located behind the intake, next to the throttle body. While the engine is running, locate this component and place your finger at the vacuum port to check its functionality. If your finger experiences vacuum suction, it indicates that the canister purge valve is stuck and needs to be replaced. Simply replace the used canister purge valve with a new and correct one.
Once you have completed the repair, use the Zeus app to clear the error code and rescan your vehicle to ensure that the issue has been resolved.
