I have a 1999 oldsmobile aurora, northstar motor. I was told I need to replace my purge valve solenoid. Can someone please tell me where it is located?


It's under the plastic cover on top of the engine . Remove the intake manifold top cover.
Remove the solenoid quick-connect hose (3) at the EVAP canister purge solenoid (4). Remove the solenoid quick-connect hose (7) from the EVAP canister purge solenoid (4) to the enhanced EVAP service port (8). Remove the electrical connector (6) at the EVAP canister purge solenoid. Remove the EVAP canister purge (2) solenoid valve bolt. Remove the EVAP canister purge solenoid tab from the bracket (5).

1999 Pontiac grand am se, what is the purge valve?


A purge valve is a solenoid valve that is opened by a computer to pull the fuel vapors out of the charcoal bead filled canister that stores them, This is called the fuel evaporative emission system. It is located under the car near the fuel tank behind the driver wheel well I think.

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.

    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.

    Getting an engine code 1450 on a 2003 ford Explorer 4.0 SOHC. Cleaned and inspected EVAP canister vent solenoid. Replaced EVAP canister purge valve. Any suggestions?


    Did you check the block box connected to the vent solenoid? There's a hose that comes off it that appears to run nowhere, that's the fresh air vent. If it's blocked it won't allow air into the system which will set the trouble code. If that's clear, the vent solenoid itself is bad and needs to be replaced.

    PO441 check engine light on v6 99 camry with 99,000 miles . I have done hours of research, what is most likely culprit?


    There's no most likely culprit... this code may mean that one of more of the following has occurred:
    • Bad vacuum switch
    • Broken or damaged EVAP line or canister
    • Open in PCM purge command circuit
    • Open or short in Voltage feed circuit to Purge Solenoid
    • Faulty purge solenoid
    • Restriction in EVAP solenoid, line or canister
    • Corrosion or resistance in purge connector
    • Bad PCM
    However, this code is tricky to diagnose. Here are some solutions you can try:
    • Replace Leak Detection Pump / LDP
    • Repair damaged EVAP lines or canister
    • Repair open or short in voltage feed circuit to Purge Solenoid
    • Repair open in PCM purge command circuit
    • Replace purge Solenoid
    • Replace vacuum switch
    • Repair restriction in Evap line or canister or soleniod
    • Repair resistance in purge connector
    • Replace PCM
