Did You Get Gas and Leave the Vech Runnung while Filling Up ??
This will turn CK ENG light On !! and Cause EVAP Code ??

Is The Fuel Filler Neck Rusty ?? UNDER VECHILE) any vapor leak preventing vacum to build will set this code !!!

SOURCE: Location of the Purge Control Valve for 1998

The correct "Hyundai" term for the valve that's attached to the Vapor Canister is the "Canister Control Valve".Why don't you try to clean the old one first. They get clogged with little bits of charcoal from the canister. It's simple so see if it's bad, take it off, and try to blow through the canister side with no electric going through. You shouldn't be able to blow because the valve is supposed to be closed. If you can blow it's because the valve is clogged and hanging open. If it is clogged, you might try and clean it.

Then take the hose off from the canister and clean the hose too, you'll get a handful of charcoal out before your done. If you don't clean the hose out, you'll probably clog the valve again, even if it's new.

That's why they usually change the canister and the valve at the same time. It gets clogged because you fill the tank to the max, it floods the canister with gas, and the charcoal floats up through the hose to the valve.

SOURCE: What is EVAPORATIVE EMISSION...Purge Flow?? Mitsubishi Mirage?

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. Try changing the gas cap first then check the rubber hoses that are visble on top of the engine. Vote "Yes" for me!

P0445 on my 2003 hyundai tiburon Gt evap


This code's description is P0455 Evap Emission System- Large Leak. Usually ,arge leak means you drove or still driving your vehicle with loose or missing gas cap. Check your gas cap if it is tight. Even if that is the case , tightening it might not turn the check engine light off. So you have to erase the code with a scanner. If your gas cap is in place and tight then you probably have a leak in the emission system which includes numerous parts. So it should be inspected by a proffesional.

Code: P0455 Evaporative Emission Control System


start by removing and replacing your gas cap
also unhook the battery for a few minutes to reset the computer.
If this does not work there may be a vacuum leak in one of the hoses going,coming from

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.

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

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


P0442 Evaporative emission (EVAP) system - small leak 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.

Code, p0442 p0445


P0442 - Evaporative Emission Control System Leak Detected (small leak)

This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. 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 P0442 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)
* A small leak/hole in a fuel vapor hose/tube
* Other small leak in EVAP system
* Faulty vent o-ring seal

Possible Solutions: with a P0442, the most common repair is to:
* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, or
* Inspect the EVAP system for cuts/holes in tubes/hoses



P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted.
Possible Solutions: with a P0445, the most common repair is to:
* Bad or loss contact wires
* Check harnesses, replace it


Hope helps (remember to rate this).

What does po440 on a 2003 saturn vue mean with a service engine soon light on


That is a problem in the evaporative emission control system.
Could be anything causing it
Clogged filter in the charcoal canister
A leak in one of the vacuum lines
The purge valve not working,,,etc.
The best thing is to take it and have it checked out, they might have to do a smoke test to find the problem.
All they do is inject smoke into the system, if there is a leak the smoke will come out of it. All it takes is a pin hole in these emission systems to screw it all up.

P0452 Evaporative Emission System Pressure Sensor/Switch Low
P0453 Evaporative Emission System Pressure Sensor/Switch High

P0455 Evaporative Emission System Leak Detected (large leak)
P0456 Evaporative Emission System Leak Detected (very small leak)
P0457 Evaporative Emission System Leak Detected (fuel cap loose/off)
P0458 Evaporative Emission System Purge Control Valve Circuit Low
P0459 Evaporative Emission System Purge Control Valve Circuit High
---
At least the cap isn't loose for the gas tank.

I would clear the code with an OBD-II Scanner 'erase code' button, and see how long it takes for it to come back.
