What does code 440 mean on a 2000 Chevrolet Malibu


P0440 - is a large EVAP leak. The EVAP system stores fuel vapor from the fuel tank and then delivers it into the engine under certain condition. The EVAP system basically consists of a purge solenoid, vent solenoid, charcoal canister, fuel tank and a fuel tank pressure sensor.

There are two common causes for this code. One is the fuel cap, make sure it is tight. Also check the filler knock where the gas caps seals to see if there is an excessive amount of rust build up which can also cause this code.

The other is the vent solenoid. If it sticks open the system will not be able to go into a vacuum mode. The vent solenoid is usually tucked up in the quarter panel on the drivers side right behind the tire.

A scan can tool is usually needed to monitor data and activate solenoids.

What is code p0440


EVAP Emission Control System Malfunction.
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

It is coming up with p440 code


P0440 - Evaporative Emission Control System Malfunction

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.

Symptoms: You likely won't notice any drivability problems.

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

Other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0446 - P0453 - P0455 - P0456

P0440 - Evaporative Emission (EVAP) System


evaporative emission (EVAP) system has a large leak.
Check the gas cap or vent valve. these are the most common problems.


The Powertrain Control Module (PCM) at different times performs various tests on the EVAP system. OBD II Enhanced EVAP systems are in place to keep fuel tank vapors from venting into the atmosphere, and instead purges them into the engine to be burned. Regular pressure tests are conducted by the PCM to monitor the sealed system for leaks. The PCM monitors the EVAP system pressure by watching the Fuel tank pressure sensor (FTP). When the sensor indicates a small leak in the EVAP system, this code is set.


Here are some additional causes.

* A small leak in any of the EVAP hoses or fuel tank hoses
* A small leak in the purge valve or vent valve
* The EVAP Canister may be leaking
