The P1443 code almost always has to do with certain elements of your Evaporative Emission control system, often referred to as simply the EVAP system. The EVAP system traps and contains potentially environmentally harmful vapors within the fuel system. Those vapors then go through the purge control valve into the engine so they can be combusted, which turns them into less harmful emissions that your engine can then release. When this control valve is malfunctioning in some way, you’ll receive this code.
More About the P1443 Code
Although issues with the Evaporative Emission system are the most common reason for the P1443 code, there are many different specific definitions related to the EVAP system, as well as some definitions outside of this system, that you might experience with the P1443 code. That includes the following:
- Audi, Volkswagen: Exhaust gas recirculation (EGR) valve position sensor – low input
- BMW: Oil pump circuit – open circuit
- Citroen, Peugeot: Evaporative Emission Control System Control Valve
- Eagle, Ford, Infiniti, Jaguar, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Saab, Subaru, Suzuki: Evaporative emission (EVAP) canister purge system/valve
- Honda: High voltage contactor/bypass contactor – contactor stays activated
- Hyundai: Evap.System-Tank Cap Missing
- Lexus, Toyota: Secondary air injection switching valve, bank 2 – circuit malfunction
- Mini: Leakage Diagnostic Pump Control Circuit Signal High
These are all good reminders to check the description of the code, not just the code itself.

What Are the Symptoms of a P1443 Code?
Because there are many different possible underlying causes, there are also many different symptoms. You should notice the check engine light come on, which should be your first indication that there’s a problem. Your problems can also include preventing the vehicle from passing an emissions test. If the valve is stuck open, you might experience rough and erratic idling; if the valve is stuck closed, pressure may build up too high in the EVAP system, causing leaks and other problems that will be associated with different codes.
What Are Some Causes of a P1443 Code?
A problem with your purge valve, control solenoid, or charcoal canister are three of the most common causes of this code. Wiring and connectors that are burnt, damaged, or corroded may also contribute to this code, although it’s most common to see other codes if this is the primary problem. Your vacuum lines may also be impacted, whether they’re damaged, split, hardened, dislodged, or generally degraded. Lastly, it is possible that the powertrain control module (PCM) is faulty, although this is very rare and should only be considered as a final likelihood.
How Serious Is the P1443 Code?
The severity of this code has to do with the symptoms and causes of the problem. For example, if the EVAP purge valve is stuck closed, it’s likely to result in leaks along your EVAP tube, which can result in very serious problems with your vehicle’s handling. It’s also common to see issues with passing an emissions test, which can be expensive and time-consuming. Assume that this code is generally fairly serious and try to fix it as quickly as possible.
Can I Still Drive with a P1443 Code?
You can often drive your vehicle to the repair shop if you’re experiencing the P1443 code. However, if you’re noticing drivability problems, you might want to contact them first to see whether they recommend you drive the vehicle to the shop or get a tow truck.
How Easy Is It to Diagnose a P1443 Code?
This code can be a bit complicated to diagnose; there are multiple different causes of the code, and understanding the right cause can be more difficult than you might assume. Additionally, if you’re seeing any other codes within your engine, you’ll need to incorporate those codes into your understanding of the P1443 code in the first place.
How Difficult Is It to Inspect a P1443 Code?
Inspecting a P1443 code can be difficult because you need to know what the charcoal canister, purge valve, wiring, and vacuum lines look like normally before you can tell whether they’re malfunctioning. An expert will know this, but you might not, which is another good reason to bring your vehicle in for help.
Need Additional Help with Your P1443 Code?
If you’re experiencing issues within your EVAP system, then there are a wide variety of problems that you might be seeing in your car, and there are also many different causes that you might experience within the system.
