In the solution for the po440 code on the 2001 toyota camry ce, what's a filler cap?


The filler cap is the GAS CAP. This code will come on if you forgot to tighten ( or drove around with it hanging) your gas cap after filling up the gas tank. If this is the case then all you have to do is tighten the gas cap until 3 clicks are heard. The code will reset itself after several days of driving. If the code does not reset then you may have a defective gas cap or another leak in the fuel emission system.

99% of the time the code is caused by a gas cap that was not tightened properly.

here are more details for P0440

Service engine soon code po440 2002 chevy trailblazer


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

Check engine light came on, ran codes and got miss fire on #6 hole. changed plugs and cleared code, light came on again. ran codes and came up with P0440 evap. checked lines and found no defect. cleared...


Would guess that canister would be dealer only but never hurts to check the local parts store.Could also check online parts store.They say this problem comes from topping of your tank.When fueling and the pump shuts off you are not to put any more in.Just a thought.

I have an 03 Ram 1500, engine light is on, I had


p0440 - Evap. system performance (this could be something as simple as not turning the gas cap several times after you fill up.

p0456 - Evap leak monitor Small leak detected. - Could be related to the previous code.

p2106 - Throttle Actuator Control System - Forced limited power : This one you might have noticed the vehicle running rough, overdrive not working properly and cruise control will not set.

p2175 - Throttle Actuator Control System - Low airflow detected.

What you might want to try first is have the codes cleared which most auto parts stores offer this for nothing (unless you have a programmer then you can do it yourself). Pour in some fuel injector cleaner into your gas, put a new air filter on. And when you fill up your gas tank, crank the cap several times when you put it back on.
See if the codes come back on after that.

I had that exact code a couple weeks ago. Mine needed new oxygen sensors. They(there are 2, only one was throwing a code, but I had both replaced) cost a little over $100 to have replaced.

Check Engine Light won't go off


If you have an Advance Auto Parts store where ever you are, they will read the code and tell you exactly what to code is and what it means. Any mechanic who "guesses" isn't a mechanic at all - he's a thief. Emissions leak can be any number of things, but not the gas cap!
