440 code is the evap vapor system failure and the 1675 is an error code for the solenoid that controls that system, IT appears they are related. If you did any maintenance on the vehicle you may have knocked a connector loose. If you did not have any maintenance done then it would be a solenoid valve or cable / connector failure

DTC P0440 Evaporative Emission (EVAP) System
Circuit Description
The evaporative system includes the following components:
• The fuel tank
• The evaporative emission (EVAP) vent solenoid
• The fuel tank pressure sensor
• The fuel pipes and hoses
• The vapor lines
• The fuel cap
• The evaporative emission canister
• The purge lines
• The EVAP purge solenoid
The evaporative leak detection diagnostic strategy is based on applying a vacuum to the EVAP system and monitoring the vacuum decay rate. The vehicle control module (VCM) monitors the vacuum level via the fuel tank pressure sensor input. At an appropriate time, the EVAP purge solenoid and the EVAP vent solenoid turn ON, allowing the engine vacuum to draw a small vacuum on the entire evaporative emission system. If a sufficient vacuum level cannot be achieved, a large leak or a malfunctioning EVAP purge solenoid is indicated. The following conditions can cause this problem:
• A disconnected or malfunctioning fuel tank pressure sensor
• A missing, malfunctioning, improperly installed, or loose fuel cap
• A disconnected, damaged, pinched, or blocked EVAP purge line
• A disconnected or damaged EVAP vent hose
• A disconnected, damaged, pinched, or blocked fuel tank vapor line
• A disconnected or malfunctioning EVAP purge solenoid
• A disconnected or malfunctioning EVAP vent solenoid
• An open ignition feed circuit to the EVAP vent or purge solenoid
• A damaged EVAP canister
• A leaking fuel sender assembly O-ring
• A leaking fuel tank or fuel filler neck
Any of the above conditions can set a DTC P0440.

There has been a service bulletin isued for that code. I have run into this before, also the wires comming out of the connector. That would bethe first thing to check. Here is what the bulletin states. Emissions - SES Lamp ON/DTC P0440 (EVAP) SetNotesFile In Section: 06 - Engine/Propulsion SystemBulletin No.: 02-06-04-044Date: August, 2002TECHNICALSubject: Service Engine Soon (SES) Light Illuminated, DTC P0440 Set (Replace Fuel Tank Evaporative Emissions Control System (EVAP) Vent Solenoid Harness) Models: 2000-2002 Chevrolet Cavalier2000-2002 Pontiac Sunfire ConditionSome customers may comment that the SES light is/was illuminated.A technician may find DTC P0440 is stored in the PCM.CauseThe EVAP solenoid harness may be misrouted around the rear antilock brake (ABS) wire harness causing a chaff/damage to the EVAP vent solenoid harness, setting DTC P0440.CorrectionFollow the service procedure below to diagnose and correct this condition.1. Install a Tech 2 scan tool and select the appropriate vehicle. Verify that a DTC P0440 is stored in the PCM. 2. Raise the vehicle on a hoist. Refer to Lifting and Jacking the Vehicle in General Information (SI Document ID # XXXXX).



Locate and inspect the EVAP vent solenoid harness (3) routing. The harness may be routed below the ABS wiring harness (4) at the right rear corner of the fuel tank, causing stress on the EVAP solenoid harness (3).





4.Disconnect the EVAP vent solenoid harness (3) from the EVAP vent solenoid (2) and connector C313 (1). Discard the EVAP vent solenoid harness (3).

5.Connect the new EVAP vent solenoid harness (3), P/N 22687059, to the EVAP vent solenoid (2), route the harness above the rear ABS harness (4) and connect the EVAP vent solenoid harness (3) to connector C313 (1).

6.Lower the vehicle.

7.Clear the DTC's with the Tech 2 scan tool.

If all of the wires are good you will want to check for any leaks in the evap system.

Hope helps.

Trouble Code: P1676 (3.8L V6 VIN K Auto)
Evaporative Emission (EVAP) Purge Solenoid

Number of Trips to Set Code: 1
OBD II Monitor Type: CCM Details
Indicators: MIL Details

• PCM Details
• MIL Details

Trouble Code Conditions:
Conditions for Setting the DTC.

• The ignition is on.
  
• An improper voltage level has been detected on the output circuit which controls the EVAP purge solenoid.
  
• The above conditions are present for at least 30 seconds.
  

Possible Causes:

• Poor connection at the PCM. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.
  
• Damaged harness.
  
• Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM, turn the ignition on and observe a voltmeter connected between the EVAP purge solenoid control circuit and ground at the PCM harness connector while moving connectors and wiring harnesses related to the EVAP purge solenoid. A change in voltage will indicate the location of the malfunction.
  

1998 Chevrolet Lumina - Powertrain - Engine Controls - 3.8L - DTC P1676 Evaporative Emission (EVAP) Purge Solenoid Control Circuit

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

Hi,

A quick Internet search on those codes pulled up the following info.
http://www.obd-codes.com/p0440

• 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

http://www.obd-codes.com/p0300

• Faulty spark plugs or wires
• Faulty coil (pack)
• Faulty oxygen sensor(s)
• Faulty fuel injector(s)
• Burned exhaust valve
• Faulty catalytic converter(s)
• Stuck/blocked EGR valve / passages
• Faulty camshaft position sensor
• Defective computer

p0440 code means that the evap system has a leak. This could be caused by a bad or improperly installed gas cap. Either that or the purge solenoid has failed or the canister is plugged and not working properly.

the evap can simply be the gaz cap the 300 check for a good spark you may need wire and plug be carefull for those coil they offent defect good luck pierre
