Smoke test the system . P0442 small leak .
This DTC tests the evaporative emission (EVAP) system for a small leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the vacuum decay rate. At an appropriate time, the control module turns the EVAP canister purge solenoid valve ON and the EVAP vent solenoid valve ON. This allows the engine to draw a vacuum on the EVAP system. At a calibrated time, or vacuum level, the control module turns the EVAP canister purge solenoid valve OFF, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum decay. If the control module detects a leak larger than a calibrated amount, this DTC sets.

I HAVE A 2001 CHEVY CAVALIER 84,675.00MILES . THE CHECK ENGINE LIGHT KEEPS COMING ON AND HAS BEEN CHECKED BY A MECHANIC SEVERAL TIMES. I REPLACED THE GAS CAP. THE CODES KEEP COMING UP A READING OF P4400. ...


P0440 is a large evap leak, so it should be pretty obviuos. first check if the vent valve is closing. then check when the purge valve is closed that its not leaking. He needs to COMMAND the vent valve closed and then smoke it. He should be able to command purge and close the vent valve, then turn off the purge and watch the vacuum level to know if its fixed or not.

I have a Pontiac torrent 2006 and I receive the ccodes P0442 small leak from and P0771 lean bank1,previously went to dealer they kept saying gas cap. I need help I think its the converter or oxygen sensor...


A p0442 code is solved by replacing the gas cap in most cases, especially if it is the original gas cap. As for the p0771 lean code, there are many issues that can cause this code, O2 sensor, small exhaust leak, spark plug or fuel injector issue, spark issue...the list goes on. This code will need a good understanding with diagnostic procedure and testing and a scan tool would help. You may get lucky with replacing the spark plugs and checking for an exhaust leak and repair the exhaust. A scanner will allow you to see what the engine management components are doing while the engine is running. Keep in mind, it may take several good trips to turn the check engine light off after repairs are made and codes are erased.

F-150 ford truck check engine light keeps coming on


Did you replace the gas cap? Also check the filler tube that's where the gas cap snaps on where you put gas in. The filler tube or neck has a thin lining of plastic at the top look for small cracks in it where the gas cap goes on. It there's cracks in it, it will cause an emission leak and sometimes a dealer won't find it until you spent a lot of money on diagnostics. And it depends if there best mechanic was working on it.

Jeep comes up with EVAP Emission Control System code- please help


YES A CAP FROM THE DEALER WILL MOST LIKELY SOLVE THIS ISSUE...SOME OF THE AFTERMARKET CAPS ARE NOT MADE TO THE PROPER SPECS TO MAINTAIN PROPER PRESSURE/VACUUM ON THE SYSTEM WHEN THE EVAP TEST BY THE COMPUTER OCCURS

P0442 check engine light code


The computer that read the code for you can also reset it.  If you don't have one, you can go to your local auto parts store and have them reset it for you.  This is what your code means P0442 Evaporative Emission Control System Leak Detected (small leak).  This is what Causes it and possible fixes: CausesA code P0442 most likely means one or more of the following has happened:
  • A loose or improperly affixed gas cap
  • A non-conforming gas cap (i.e. not factory/original brand)
  • A small leak/hole in a fuel vapor hose/tube
  • Other small leak in EVAP system
  • Faulty vent o-ring seal
Possible SolutionsWith a P0442, the most common repair is to:
  • Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
  • Otherwise, replace the gas cap, or
  • Inspect the EVAP system for cuts/holes in tubes/hoses
