Replaced front and fuel tank evap solenoid still getting po443 code on 2011 chevy cruze what is a solution

Your car is run by a computer, it the P0440 code comes up, that is what needs fixing. If you see the ETS Light, it is telling you that Traction Control is turned off. Fix the EEC and then clear the code. Then look for the ETS issue.

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.

Fuel filter? Sometimes if it is plugged, it doesn't let enough gas through to keep the car running. Just a wild guess...

Code po443 is for EVAP purge solenoid malfunction which will cause the car to stall. Also over filling gas also causes the EVAP canister to choke with excess gas.
Please perform the following test the component failure:-
Tests/Procedures: 1. Monitor the purge solenoid for having 12v Key On Engine Running (KOER).

2. Using a voltmeter attached to the White wire, monitor for 12v to come and go.

3. Check the purge solenoid for clicking at idle. Tech Tips: If the voltage is alternating from 12-0 volts, that indicates that the ECM is trying to trigger the solenoid. If there is no clicking, the solenoid is faulty.

Possible causes - Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking The P0455 it's a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes.

When is the code detected? EVAP control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors P0455 Buick Description This diagnosis detects leaks in the Evaporative Emission System (EVAP) purge line using engine intake manifold vacuum. If pressure does not increase, the Engine Control Module (ECM) will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition. The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.
if tightening the cap or replacing the cap does not help take your car to a shop to have it diagnosed as it requires special tools/equipment to test this and get an accurate results to find what needs replacing.

p0443 is a EVAP code. The EVAP system deal with the vapor of your fuel tank. The definition of P0443 is EVAP purge valve circuit malfunction. The purge valve solenoid is locate on a support on the motor. There is 2 plastic hoses, one from the fuel tank and the other going to the trottle body. The most commun cause is a broken wire at the purge valve solenoid connector. The second most commun cause is the purge valve solenoid itself.

ossible causes
- Faulty Evaporative Emission (EVAP) Purge Solenoid Control
- Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted
- Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection
What does this mean?
When is the code detected?
An improper voltage signal is sent to Engine Control Module (ECM) through the valve.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P0443 Description
The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the Engine Control Module (ECM). The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

The code is for a large leak in the EVAP system such as a loose or missing gas cap. But it could also mean a loose or missing hose to the canister or other leak in the tank.
The computer vents the tank several times an hour while the engine is running, and it checks the system by pressurizing the gas tank. If the tank will not hold pressure the code is set.
You may have to check the top of the tank where the fuel pump gasket is, as well as the vent lines to the front of the car.
A mechanic would perform a smoke test to look for leaks.

PO440 Possible Causes:
Charcoal canister is loaded with fuel or moisture
Fuel filler cap is loose, cross-threaded, damaged or wrong part
Fuel tank, fuel filler neck or fuel sending unit 'O' ring is leaking
Fuel tank pressure sensor is damaged, disconnected or it failed
Fuel tank vapor line(s) is clogged, damaged or disconnected
Purge valve vapor line is clogged, damaged, or disconnected
Purge or vent solenoid power circuit is open (check the fuse)
PCM has failed

PO443:
Purge solenoid control circuit is open or shorted to ground
Purge solenoid control circuit is shorted to system power (B+)
Purge solenoid power circuit is open (test the ENG1 fuse)
Purge solenoid is damaged or has failed
PCM has failed

PO449:
Sames as PO443.

Hope this helps.
