P2450 - OBD Trouble Code

If the engine control module would detect a variation in the voltage coming from the evaporative emission system switching valve that is outside the parameters set by the automobile manufacturer, then it would store the P2450 error code. This would also give rise to the illumination of the check engine light.

What causes this problem with the Evaporative Emission System Switching Valve Performance/Stuck Open?

• Some issues related to the evaporative emission system switching valve
• Unlocked evaporative emission system switching valve harness
• Unsatisfactory electrical connection in the evaporative emission system switching valve circuit
• Malfunctioning engine control module

1. EVAP Leak Detection Pump - The main purpose of the LDP (Leak Detection Pump) is to pressurize the fuel system for leak checking. It closes the EVAP system vent to atmospheric pressure so the system can be pressurized for leak testing.
2. Vapor Canister Valve - In modern cars, the purge valve is an electrically-operated solenoid that is controlled by the engine computer. When the engine is off, the purge valve is closed. When the engine is running and fully warmed up, the engine computer gradually opens the purge valve to allow some amount of fuel vapors to be moved from the charcoal canister and burned in the engine. The purge flow is monitored by a number of sensors. If the purge flow is less or more than is expected under the conditions, the computer illuminates the "Check Engine" light.
3. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have best auto parts for our customers.
4. Vapor Canister Purge Solenoid - The canister purge solenoid is the component in the EVAP system that is responsible for “purging” the EVAP system, by acting as the switch that allows the vapor into the engine. When the purge solenoid fails, it will cause problems for the EVAP system, which will affect the vehicle’s emissions output levels.
5. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
6. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2450 code to be stored:

• Get proper access to the system by removing the fuel tank. Then loose, broken, or damaged wires and electrical connectors must be repaired.
• Check the lines for any cracks or holes. If everything seems to be okay after a visual inspection, then simply replacing the sensor can resolve the problem.
• Also inspect for evaporative emission system switching valve and if it looks good, then simply unplug all related controllers, and retest individual circuits using the DVOM. Replace open or shorted circuits as needed.
• In many cases, the components of EVAP emission control system are needlessly replaced when there is a vacuum leak present, or the fuel cap is simply not properly tightened. Thus, it is important to conduct a thorough diagnosis to make sure you don’t waste money on replacing fully-functional components.

Common Mistakes When Diagnosing The P2450 Code

• The most common mistake associated with a P2450 code is not properly inspecting all components, wiring, and connectors before replacing any part of the evaporative emission control system. For example, in some cases, a vacuum leak could be due to a loose or damaged fuel cap, not a faulty vacuum hose.
• Thus, it is important to carefully inspect all the components in question and thus need to follow proper quality and operational check also.
