SOURCE: check engine light came on, says its a evaporative

What does that mean?
This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Possible Causes:
A code P0440 could mean one or more of the following has happened:

  • The gas cap is not installed or working properly
  • The purge solenoid has failed
  • The canister is plugged and not working properly
Possible solutions:
With a P0440 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
  • Inspect the EVAP system for cuts/holes in tubes/hoses
  • Inspect for damaged or disconnected hoses around the Evap purge solenoid
  • Check and/or replace the sensor
  • Check and/or replace the purge valve
  • Have a professional use a smoke machine to detect leaks
HTH,

Mike...

What are the probable causes of DTCs P0300, P0440, C1298, and C1245?


P0300 means you have a misfire in multiple cylinders
P0440 means there is a malfunction with the Evaporative Emission Control System.

The engine will be running very rough and potentially it could stop altogether.


You need to get the vehicle to a competent mechanic to diagnose the cause of the problems because there are a number of factors that could be causing these engine problems and the fault codes that are being generated as a result. .

P0440 and P0302 scan code - changed plugs and wires. Changed emission purge valve. All vacuum lines appear to be OK. Fuel lines are not leaking. Good spark to cyclinder two when using spark tester. ...


Cylinder 2 Misfire Detected po302 . Evaporative Emission Control System po440 The last digit on a misfire code indicates the cylinder number. A code P0302, for example, would tell you cylinder #2 is misfiring. Chances are the misfire is due to a weak ignition coil. Did you change the pcv valve? Remember to put the o-ring on the new one or this problem will happen.

Scan with code reader P0440 EVAC SYSTEM MALFUNCTION. It also informed me that my O2 sensor, EGR valve and catalst was not reading. I would like to do the repairs my self. would a faulty O2 sensor cause...


p0440 is a failure in the evaporative system, could be a hole in lines or a bad gas cap. screw cap on tighter to see if this may be your problem. the vent in the cap may not be letting pressure out, so loosen it to see. 02 sensor is a different code. have vehicle scanned to find codes. 02 sensor, egr, are part of the emission system etc. have a good day!!
