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
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
Get a new gas cap first to try.
thanks

This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

Replacing it is the only fix. Sounds like it may be sticking open slightly.

2003 chevy trailblazer service engine soon light


If the service engine soon light is flashing, it means the computer has detected an engine misfire with the potential of catalytic convertor failure. Don't just tune it up. Bring it somewhere they can read the trouble code. Sometimes it will designate which cylinder is having the problem.

You need to get the fault codes read to determine where the problem is that set the SES light. Autozone will scan your car at no charge. At some point you will need to get a mechanic involved to further diagnose the codes.

If the service light is on in your TrailBlazer, open the door, turn the key to ignition position and push the accelerator pedal 5 times, the service light will flash. flash your high beams and you're done.
