How to diagnose and repair code p0442?
How To Diagnose And Repair Code P0442? Scan your vehicle to verify P0442 is the only code present. If other codes are present regarding fuel pressure or the fuel system, repair and diagnose those first. If it is paired with P0441, P0440, and/or P0446, there is most likely a solenoid failure, leaking charcoal canister, or a more complex EVAP leak.

Is it OK to drive with EVAP leak?
Yes, you are still safe to drive. The EVAP (Evaporated Emission Control System) is used to prevent gasoline vapors from escaping into the air from the fuel tank system to control greenhouse emissions.
How much does it cost to fix an EVAP leak?
In general, you should expect to pay around $200- - $400 for your EVAP system leak repairs, but you should confirm that this is the case where you live. The price breakdown for different vehicles is listed below. These prices will vary depending on where you live and the specific repairs your EVAP system needs.
Is EVAP leak serious?
But because an EVAP leak can potentially be a severe and environmentally damaging problem, it's not a good idea to keep driving with the check engine light on. Whatever condition your vehicle is in—whether it's showing symptoms of a fuel leak or not—aim to have the codes pulled as soon as possible.
Will P0442 fail emissions?
What is this? If you are in a state or county where you need an emissions test, you're not going to pass with a code P0442. Even though it's a smaller size leak, most emission testers will automatically fail your vehicle if any emissions-related engine codes are present.
How long does it take to fix an EVAP leak?
An EVAP leak can be a serious issue that requires repair as quickly as possible. Fortunately, if you're able to find and repair any leaks in your vehicle's EVAP lines, it will usually only take a few hours or less. However, it is not recommended to drive with an EVAP leak for more than 30-50 miles.
What would cause a small EVAP leak?
The most common causes for EVAP leaks include bad seals and O-rings, a failing purge valve, a damaged hose or vent, or a defective leak detection pump. As you might have guessed, there's no real way to prevent one of those components from failing unless you'd like to regularly replace components of your fuel system.
Does EVAP leak affect gas mileage?
When a canister purge valve doesn't open as it should, your gas mileage might be negatively affected. The vapors in your car used in combustion will go to the EVAP canister then get vented out into the environment, causing you to use some of the fuel that your car would usually use for burning.
Can you smell an EVAP leak?
One of the most obvious signs that you are facing an EVAP leak is the smell of fuel. The gas you put into your vehicle is liquid, but it becomes a gas form in the system, creating many fumes. The smallest fault in the EVAP system can allow a vapor leak that creates a noxious odor.
Can EVAP leak cause misfire?
The cause could be anything from a hard to find vacuum leak to dirty fuel injectors, low fuel pressure, a weak ignition coil, or compression problems. A leaking EGR valve can cause a random misfire and act like a vacuum leak.
How serious is P0442?
Leaking fuel tank. How Serious Is Code P0442? – Low. It is unlikely the driver will notice any symptoms with check engine light code P0442 other than a slight odor of fuel, a slight decrease in fuel economy, and the check engine light.
What is a P0442 medium leak?
The P0442 medium leak is a bit trickier to diagnose. Also, many manufacturers have technical service bulletins regarding EVAP codes. Be sure to check if your vehicle has any technical service bulletins available to save time diagnosing and/ or misdiagnosing the car.
What to do if gas cap is not loose?
If your gas cap was not loose and you do not see any indications of failure, try replacing the gas cap anyway and clearing the codes.
What P0442 really means
The Evaporative Emission System is designed to prevent gasoline vapors from escaping into the atmosphere, and is built around a series of valves, rubber hoses, and a charcoal canister meant to collect vapors as they build up. These vapors are then systematically sent to the engine to be burned off.
What are the causes of a P0442 code?
It is good to remember that these leaks are very small, in many cases small pinholes, and you should not worry about gasoline gushing out of the car. With the P0442, these small leaks are commonly seen on older cars, as rubber hoses and gaskets dry out.
What is the severity of a P0442 code?
Minor. These size leaks should not make the car run poorly. It will need to be resolved before an official emissions test.
What repairs are needed to resolve a P0442 code?
New hose, rubber gasket, or fuel cap replacement are the most common repairs. Because there is no noticeable change in how the car runs, many people will wait until just before an official emission or smog check to get it replaced. However, this may not be the best course of action, as this code usually will take some time to diagnose.
What is the cost to resolve a P0442 code?
The diagnosis might be the most expensive part of the bill. Unlike larger leaks, where components have failed or hoses have broken in half, small leaks are much harder to find.
The Code
Your Vehicle’S Evap System
- As youlikely know, modern vehicles have a way to minimize emissions. Yours probablyhas hoses that direct fuel vapors into a charcoal canister. When the canisterbecomes full and your vehicle’s engine engages, a purge control valve opens.The purged fuel vapors enter the engine where they burn off, decreasing overallemissions. As with any system of hoses, valves and vacuums, leaks …
Warning Signs
- Unlike some other vehicle problems, a leaky EVAP system may not reveal itself by causing your vehicle to run poorly. Instead, you are likely only to see an illuminated check engine light. Depending on the location of the leak and its size, though, you may smell fuel fumes. That said, using an OBD-II diagnostic scanner to read your vehicle’s codes is the best way to diagnose prob…
