SOURCE: P0440 Evaporative Emission Control

You need a charcoal canister and vent control valve.

You also need the EGR solenoid valve (I think it the brown one).

Valve is located in the valley of the V, towards the transmission side of engine.

Do these 1st and reset light. You may have other issues but you have to start here.

SOURCE: car codes

When you have P0440, P0441 and P0446, it is a very good bet that the fuel cap was loose, or the fuel cap rubber seal is compromised. You will get all three of those codes every time that the cap is loose. Always make sure that the fuel cap is as tight as you can get it after you refuel.

SOURCE: I had an emission test done on my 98 bonneville

Here's list why your car is coming up with this code. It could be any of these things causing it.
DTC detecting condition:

  • EVAP control system has a leak.
  • EVAP control system does not operate properly.
Possible cause:
  • Incorrect fuel tank vacuum relief valve
  • Incorrect fuel filler cap used
  • Fuel filler cap remains open or fails to close.
  • Foreign matter caught in fuel filler cap.
  • Leak is in line between intake manifold and EVAP canister purge volume control solenoid valve.
  • Foreign matter caught in EVAP canister vent control valve.
  • EVAP canister or fuel tank leaks
  • EVAP purge line (pipe and rubber tube) leaks
  • EVAP purge line rubber tube bent
  • Blocked or bent rubber tube to EVAP control system pressure sensor
  • Loose or disconnected rubber tube
  • EVAP canister vent control valve and the circuit
  • EVAP canister purge volume control solenoid valve
  • EVAP canister purge volume control solenoid valve and the circuit
  • Absolute pressure sensor
  • Fuel tank temperature sensor
  • O-ring of EVAP canister vent control valve is missing or damaged
  • Water separator
  • EVAP canister is saturated with water
  • EVAP control system pressure sensor
  • Refueling control valve
  • ORVR system leaks
  • Fuel level sensor and the circuit

SOURCE: check engine light is on-

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

Hope helps (remember to rate this).
