2009 pontiac g6 purge valve solenoid

code PO171 fuel trim system lean bank 1 conditions.possible causes air leaks in intake manifold exhaust pipes or exhaust manifold. fuel control sensor is out of calibration such as ECT IAT MAF.fuel component faulty like stopped up fuel filter fuel injectors clogged low fuel pressure faulty fuel pump. HO2S element contaminated or has failed. purge solenoid is part of EVAP system. if you have faulty purge solenoid you would get code like PO443 meaning evaporative emission control system purge control valve circuit malfunction.try replacing fuel filter clean fuel injectors see what happens.

Common causes for codes p0441

getting code p441 could be caused by evap purge solenoid vacuum line loose leaking or restricted, evap purge solenoid faulty, evap purge vacuum line to canister leaking or disconnected,evap canister failed.

Hi, the p0443 code is for Evaporator Canister Purge Control Solenoid Valve. The canister has charcoal in it to absorb vapors from the fuel so it can't be released into the air. When the system detects that the canister needs flushing , the purge control solenoid opens to purge the canister and the vapors are consumed by the engine,sorry I don't know where the location of this is on your car but purchasing an AUTOMOTIVE REPAIR MANUAL by Haynes from an auto parts store would be helpful. I believe the problem can be as simple as a gas cap not being tight enough! There are many things that have to work for the system to function like the solenoid / current to solenoid / leaks / stop ups etc. Like many things it's a process of elimination......... Good luck.

Ford escort wagon 1997 code p1443 displayed. what does this indicate & where is the cannister? thank you.

P1443 - EVAP Control System / Vacuum System Purge Control Solenoid Or Purge Control Valve Fault. A fuel tank pressure change greater than minus (-) 7 inches of water in 30 seconds occurred with a purge (fuel vapor) flow at less than 0.02 pounds per minute.

Possible Causes:
  • Blocked fuel vapor hose between the EVAP canister purge valve and the FTP sensor.
  • Blocked fuel vapor hose between the EVAP canister purge valve and the engine intake manifold.
  • Blocked vacuum hose between the EVAP canister purge valve solenoid and the engine intake manifold.
  • EVAP canister purge valve stuck closed (mechanically).

  • Possible Solution:
    Check for blockages between the fuel tank, the EVAP canister purge valve, and the engine intake manifold. Check for obstructions in the EVAP canister purge valve diaphragm and ports.

    The canister is on the passengers side near the firewall if I recall correctly.

    What is po411 and po445 for 2006 vw jetta/

    P0411- Means Secondary Air Injection System Incorrect Flow Detected!
    Possible causes - Vacuum hoses damaged.
    - Air Pump inoperative.
    - Air bypass solenoid circuit open.
    - Air bypass solenoid leaking/blocked or stuck open/closed.
    - Air diverter valve leaking/blocked or stuck open/closed.
    - Air air hoses r Possible solution - Visually inspect vacuum lines for disconnects in the AIR systems and visually inspect for proper vacuum line routing. Repair if necessary.
    - Disconnect the air pump hose at the solenoid valve, start the engine and see if there is air being pumped P0445- Means Evaporative Emission Control System Purge Control Valve Circuit Shorted! Possible causes - Damage harness or connectors to the Purge Control Valve
    - The valve circuit is open or shorted
    - EVAP canister purge volume control solenoid valve may be faulty
    P0445 Description The 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 ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve. When is the code detected? - An excessively high voltage signal is sent to ECM through the valve

    Code says evaporator purge solenoid

    Which code specifically? Do not assume you need a new solenoid. Our recommendation will depend on the specific code and some troubleshooting results. I usually recommend checking over all the EVAP vacuum lines and the gas cap too whenever there is a purge valve code. Check the vacuum lines at the cannister in the left rear bumper. I will paste info on the purge solenoid below.

    Evaporative Emission Purge Solenoid

    Description & Operation
    The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
    During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
    The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.
    Removal & Installation
    The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.

    1. Disconnect electrical connector at solenoid.
    2. Disconnect vacuum lines at solenoid.
    3. Lift solenoid slot from mounting bracket for Removal & Installation.

    To Install:
    1. Position solenoid slot to mounting bracket.
    2. Connect vacuum lines to solenoid. Be sure vacuum lines are firmly connected and not leaking or damaged. If leaking, a Diagnostic Trouble Code (DTC) may be set with certain emission packages.
    3. Connect electrical connector to solenoid.

    Computer is not getting current through the purge valve/solenoid. Check connection to valve. If good, you can either test the valve to see if it's bad (requires special equipment) or just replace the valve. Instructions for both are pasted below. The cost of the part is $40. Let me know if you have more questions.

    COMPONENT TESTING Carefully check for cracks or leaks in the vacuum lines or in the canister itself. The lines and fittings can be reached without removing the canister. Cracks or leaks in the system may cause poor idle, stalling, poor driveability, fuel loss or a fuel vapor odor.
    Vapor odor and fuel loss may also be caused by: fuel leaking from the lines, tank or injectors, loose, disconnected or kinked lines, or an improperly seated air cleaner and gasket.
    If the system passes the visual inspection and a problem is still suspected, proceed as follows:

    1. With the ignition switch in the OFF position, unplug the electrical connector from the canister purge solenoid. Use an ohmmeter to check the solenoid coil resistance; it should be 19-31 ohms.
    2. Turn the ignition switch ON then, disconnect the vacuum line from the intake manifold and connect a hand vacuum pump to the valve.
    3. Apply a vacuum of about 10 in. Hg (34 kPa) to the hose and solenoid, then observe if the valve holds the vacuum. If the valve does not hold, apply vacuum directly to the solenoid to determine if the solenoid or hose is at fault, then replace the component which allowed vacuum to release.
    4. If the vacuum holds in the initial test, jumper the test terminals on the ALDL (terminals A and B are the test terminals and are the two uppermost right terminals of the ALDL connector), and observe if the valve activates, releasing the vacuum. If the valve does not activate and release the vacuum, replace the solenoid.

    Canister Purge Solenoid Valve
    See Figure 2
    The purge solenoid valve is mounted on the engine, towards the rear and below the intake manifold.

    1. As an added safety precaution, you may wish to disable the air bag(s), if equipped. refer to Chassis Electrical for the air bag disabling procedure.
    2. Disconnect the negative battery cable.
    3. Remove the air cleaner/intake tube assembly.
    For DOHC engines, the solenoid can be reached through the access hole located next to the intake manifold support bracket.
    1. Unplug the solenoid vacuum hoses and electrical connector.
    2. Remove the attaching bolt, then remove the canister purge solenoid.

    To install:
    1. Install the solenoid and tighten the retaining bolt to 19 ft. lbs. (25 Nm).
    2. Connect the vacuum lines to the solenoid, then install and push in the electrical connector until it clicks firmly into place.
    3. Install the air cleaner/intake tube assembly.
    4. Connect the negative battery cable.
    5. If necessary, enable the air bag(s). refer to Chassis Electrical .
