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.

P0440 Evaporative emission (EVAP) system - malfunction

Possible causes: Hose connection(s), intake leak, EVAP canister purge valve


P0441 Evaporative emission (EVAP) system - incorrect flow detected

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.

Although I don't know the exact location on this car I can tell you what it does and why it needs replacing.The purge canister is part of your emission control system,it is full of charcoal(not kidding) and it is designed to store gas vapor rather than release it to the air ,like in the old days.When the car is moving down the road the purge solenoid opens and these stored gas vapors get burned up in the engine.Solenoids are a electro-magnetic device and they wear out.Go to the dealer,get a new one ,find the exact location,and change it out .They are usually held in with 2 small bolts or screws.The check engine light should turn itself out in a couple of days or if you have a scanner clear the code out. Good luck.

SOURCE: location of the evaporative cannister solenoid? 2003 saturn vue

Depends if the engine is 3.0 or a 2.2?
3.0 purge is on the top, back side of the intake. Black, cylinder. Looks the same on a 2.2, but is located next to the air filter.

What will cause a p0440 code to appear on 2000 chevy silverado?


What engine does it have ?
Engine Controls - 4.3L
Engine Controls - 4.8L, 5.3L, and 6.0L
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.

Check engine light code p1676 Chevy lumina Ltz


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
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.
