At least the cap isn't loose for the gas tank.
I would clear the code with an OBD-II Scanner 'erase code' button, and see how long it takes for it to come back.
P0445 Evaporative Emissions System Purge control valve circuit shorted
I guess the first thing i would do, is insure that all the maintenance on this vehicle was up to date. Do an oil change and a tune up. Make sure you use decent spark plugs as a fouled plug or bad oil could cause a misfire. After you do the tune up, try running it some more, if the problem persist, you may end up having to replace the coil.
The evaporateemission leaks. These, especially the the 442 can be either a loose gas cap or a small leak in the vacume system. Insure the cap is tight passed several clicks and listen the the motor as it runs and try to hear any leaks. If you find a leak replace the faulty lines. Also inspect the vacume line for cracks and breaks.
Wish you luck, we are hear if you need more help. Thanks for coming to FixYa!!
P0442 code relating to the EVAP (Evaporative Emission System).a small emissions leak. also check the gas cap .Try cleaning the seals first and then try putting a little vaseline on the seals before getting a new gas cap.------------- Code P0442-Evaporative emission control system. Canister Purge system failed the monitor test indicating a large leak (over 0.040”). Enabling conditions: Engine running after a 6 to 8 hour engine off period called a cold soak. The test runs when engine load is between 15 to 45% and inlet air temperature between 40 and 130°F. Blocking Action: This code can block the following monitors: Fuel Control, O2 monitor, Catalyst Monitor, misfire monitor. Testing: Check the purge hoses for leaks, leaking vapor management valve or loose gas cap.
This simply indicates that there was no flow from the evap system when the purge valve was energized. This could be cause of a few different reasons. First, check for leaks by visually looking at all evap lines for cranks rips or any tears. Basically, anywhere that fuel vapors can escape. -----------Here is the test that will smoke the system for leaks with a smoke machine.
Evaporative Emission System Leak Test
CAUTION: The evaporative emission system must not be pressurized to more than 3.48 kPa (14 inches H2O)or damage to the evaporative emission system may occur.
Connect the Evaporative Emission System Leak Tester to the evaporative emission test port.
Close the canister vent solenoid.
Pressurize the evaporative emission system to 3.48 kPa (14 inches H2O) .
Monitor the system for two minutes . The system fails the leak test if the pressure falls below 2.0 kPa (8 inches H2O) .
Repair any leaks as necessary.
Repeat the leak test until the system remains above 2.0 kPa (8 inches H2O) after the two-minute test period.
get it repaired ASAP because if you drive the car in same condition the emisson system can get damaged.and code will be p0445 ,now the code is p0442 its for leak in the emisson system.
This will help. Thanks please keep updated.please do rate the solution
positively .thank you for using fixya.
P0446 Evaporative Emission Control System Vent Control Circuit Malfunction
The evaporative emission control system checks to make sure there are
no leaks in the lines that run from the gas tank to the charcoal
canister and up to the engine. It also checks to make sure the gas cap
is sealing correctly. It may just be that the cap was not on tight and the code was tripped.
A dusty environment can also clog the vent line and cause this code. Have the code cleared and see if it comes back. Some auto parts stores like Auto Zone can read and clear the codes for you. Hope this helps.
Hi..my name is Keith..and the error code P0442 means...Evaporative emission control system,small leak detected ...and error code P0445 means....Evaporative emission control system,short in purge control valve circuit..i hope this has helped
