The definition of code P2419 is “EVAP System Switching Valve Control Circuit Low.” This code indicates that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has not been able to activate the Leak Detection Pump correctly, which is a part of the vehicle that allows it to determine whether there’s a leak in the EVAP system. As a generic powertrain code, this code can show up in engine types that use a leak detection pump instead of a pressure sensor.

More About Error Code P2419
Your Evaporative Emissions Control system (EVAP system) helps avoid fuel vapors escaping your vehicle’s system and moving into the atmosphere. Because the emission control system deals with vapors, the systems must be air-tight, which means there needs to be a method of determining whether there’s a leak in that system. In some vehicles, there’s a leak detection pump, which essentially just applies negative pressure to the system and measures whether the system holds the vacuum or if there’s air coming in somewhere. The P2419 EVAP error code doesn’t mean that the system leaks. It means that the leak detection pump isn’t activating properly.

What Are the Symptoms of a P2419 Code?
The P2419 generic engine code has no common symptoms beyond an illuminated check engine light or other malfunction indicator lamp. This error code doesn’t mean that any portion of the system is broken but that the system that detects possible leaks can’t run its diagnostic checks. Problems may arise if you have any leaks within this system, as the leak detection pump won’t be able to test for them.
What Are Some Causes of a P2419 Code?
There are a few different problems that can cause the P2419 fault code to form. A bad canister pump module is the most common, as it can create a problem where the vacuum can’t turn on at all. You might also see this issue if the vacuum canister is cracked or the purge valve/solenoid is broken. EVAP hose leaks or pinching problems can also result in the P2419 misfire code. Some wiring problems, including open and shorted wires throughout the EVAP system, can cause the P2419 code. Finally, issues with your PCM, including a faulty PCM, PCM programming issues, and other concerns, can result in the P2419 code, but this is the least likely cause.
How Serious Is the P2419 Code?
By itself, the P2419 code is not necessarily serious. You can still drive when this code is active and won’t even cause drivability symptoms. However, the problem will arise if your EVAP system ever develops a leak. Because your PCM has no way to determine whether or not the EVAP system is experiencing leakage, it won’t be able to let you know or take precautionary measures to avoid secondary problems, which can result in heavy emissions and even engine damage. This is why it’s important to fix it when you have the time.
Can I Still Drive with a P2419 Code?
You can still physically drive with the P2419 error code, as it doesn’t cause drivability symptoms. However, every mechanic will tell you that you should fix the diagnostic trouble code as soon as possible without driving on it. This is part of the series of systems that lets you know if there’s a problem, which means it’s fine until there is an actual problem. Don’t take chances with this error code. Get a fix as soon as possible.
How Easy Is It to Diagnose a P2419 Code?
Diagnosis for the P2419 code isn’t always difficult. If you’re looking for the core problem that has created the P2419 code, there are usually only a few problems that will be responsible. However, the diagnostic method may require you to inspect areas of the vehicle you’re not completely comfortable with, as the EVAP system isn’t something that many DIYers are extremely familiar with.
How Difficult Is It to Inspect a P2419 Code?
Inspection is usually the most difficult part of handling a P2419 generic engine code. To inspect the P2419 code, you’ll need some additional tools, which may include a code reader, technical service bulletins, repair guides, a diagnostic scanner, and a digital volt/ohmmeter (DVOM), all of which can help you understand the problem you’re experiencing. However, most DIYers aren’t familiar with these tools and the inspection process, so it can be helpful to talk to a certified mechanic who won’t make any of the common mistakes associated with this code.
Need Additional Help with Your P2419 Code?
Most people will need additional help with the P2419 misfire code, and that’s why it’s a good idea to talk to an expert if you have problems with yours. If you need additional help, there’s someone available to take a look.
First, you can find an auto repair shop in your area. A local auto repair shop will give you insight into the problems you’re experiencing without requiring you to travel far, which is extremely convenient.
If there are additional codes in your vehicle, it can also impact how you handle the problem. KBB.com’s OBD-II database will give you more information about how to handle different codes that might turn up on your code scanner.
