The problem is, Autozone doesn't use a scanner. They use a scan tool otherwise known as a code reader. I suggest get another opinion at a shop with an actual scanner. They would be more helpful to you. Don't just throw parts at it.

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.

HWRE CAN I FIND? FUEL EVAP TEST.


Here is a purge valve test from autozone.com. Is this what you needed, or what else?


COMPONENT TESTING
NOTE To relieve fuel tank pressure, the filler cap must be removed before disconnecting any fuel system component.
Canister Purge Solenoid

  1. Locations vary depending on model and year. Typical locations include the firewall (left or right side) and the rear of the engine near the firewall.
  2. With the ignition off, unplug the connector on the EVAP solenoid.
  3. Turn ignition on, measure the voltage at the ignition switch output line, voltage should be 10.0v or more. If the voltage reading is not 10.0 volts or more, repair the circuit from the ignition switch to EVAP solenoid.
  4. Disconnect the negative battery cable.
  5. Disconnect the PCM harness from the PCM.
  6. Check the resistance of the EVAP solenoid control circuit between the PCM harness connector and the EVAP solenoid connector. Resistance should be less than 5.0 ohms; if not, repair the opening in the circuit.
  7. Connect the negative battery cable.

I have a toyota matrix w/ 88,000 miles 2006. I have the check engine light on, took it to advance auto, codes are PO441- EVAP control system , purge flow-fault also PO455 EVAP system-large leak I don't...


P0441 Evaporative Emission Control System Incorrect Purge Flow
OBD-II Trouble Code Technical Description

Evaporative Emission Control System Incorrect Purge Flow
What does that mean?

This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

EVAP emission canister purge is contolled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
Symptoms

Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
Causes

A code P0441 could mean one or more of the following has happened:

* 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

Possible Solutions

With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

* Common Chrysler fix - 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
THIS IS LIKELY FROM TOPPING OFF THE TANK EACH TIME YOU FUEL UP



P0455 is similar:

Technical Description

Evaporative Emission Control System Leak Detected (no purge flow or large leak)
What does that mean?

This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
Symptoms

You likely won't notice any drivability problems.
Causes

A code p0455 most likely means one or more of the following has happened:

* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* Other leak or damaged piece in EVAP system

Possible Solutions

With a p0455, the most common repair is to:

* Remove and reinstall the gas cap, have AutoZone clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, and/or
* Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

Check engine light on.Took truck to checkers and it was put on scope and results came back with EVAP canister broke, and purge or vent solenoid defective and vacuum leak at engine also failed tcc or...


The codes you are getting can be caused by one of the several parts to the canister purge valve. It would best be taken to a mechanic or you may be replacing parts that you don't need. Normally the evap canister purge valve has stuck or broken or disconnected.

  • 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

With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Repair damaged EVAP lines or canister
  • Repair open or short in voltage feed circuit to Purge Solenoid
  • Repair open in PCM purge command circuit
