Where is evap canister located on 2008 kia optima

In the 2008 Kia Sportage, the purge evacuation (EVAP) solenoid is typically located near the charcoal canister. The exact location may vary slightly depending on the specific engine configuration and optional equipment, but here is a general guideline:

1. Locate the Charcoal Canister: The charcoal canister is a component of the EVAP system and is responsible for storing fuel vapors. It is usually located in the rear of the vehicle, near the fuel tank or in the engine compartment. The canister is a cylindrical or rectangular-shaped container.
2. Find the EVAP Solenoid: Once you have located the charcoal canister, look for a smaller component connected to it. This component is the purge evacuation (EVAP) solenoid. It is typically a small plastic or metal device with electrical connectors and vacuum hoses.
3. Follow the Hoses and Wires: Trace the vacuum hoses and electrical wires connected to the charcoal canister to locate the EVAP solenoid. The solenoid may be connected directly to the canister or positioned nearby.

Please note that the exact location of the EVAP solenoid may vary slightly depending on the specific engine and emission system layout of your 2008 Kia Sportage. Consulting the vehicle's service manual or contacting a Kia dealership may provide more accurate and detailed information tailored to your specific model.
It's important to exercise caution when working with the EVAP system and its components, as they are part of the vehicle's emission control system. If you are unsure or uncomfortable performing the task yourself, it's recommended to seek assistance from a qualified technician or a reputable automotive service center. They have the expertise and tools to locate and service the EVAP solenoid properly.

There are Three things that cause this code other than vacuum lines and hoses, the fuel tank pressure sensor, monitors the pressure in the fuel tank and times the vacuum decay, The canister purge valve and the canister close valve, these are all maid to be tested with a scanner but you can Do this, locate the charcoal canister and find the valves have someone turn the switch on while you feel and listen for a click. You can also check with an ohmmeter just check for continuity. If the fuel tank is rusty on top there could be a pin hole in it. I hope this helps. Take care.

code p 0442 ,is evaporative (EVAP) system---small or large gas leak====causes --hose and connections---intake leak---EVAP canister---EVAP canister purge valve ---fuel cap loose --EVAP pressure sensor ---mechanical fault

charcoal canister takes the evaporating fuel from your gas tank and prevents it from venting to the atmosfere by active charcoal.

What is Charcoal Canister with picture


here is a picture of the evap canister (charcoal canister) http://ww2.justanswer.com/uploads/CL/clmcr8/2014-02-25_203409_canisterlocation.gif

code p 0442 refers to evaporative emission(EVAP) system---small leak detected ===causes --hose connections--intake leak---EVAP canister---EVAP canister purge valve
There is another section --large leak detected in the EVAP system===causes --mechanical fault---fuel cap loose / off--hose connections ---EVAP pressure sensor

P0442 EVAP Leak Monitor .040 Leak Detected (Medium Leak)

P0456 EVAP Leak Monitor .020 Leak Detected

replace your gas cap and clear codes, then wait and see if light comes back on, if it does you have a more serious problem like a fuel tank leak or a defective fuel tank pressure sensor.

P0446 - Vent Control of the Evap System. This Evaporative Emissions System is very complicated. These particular DTCs (Diagnostic Trouble Codes) can be caused by MORE than they tell you. Three MAJOR components in the system can cause this P0446. 1. Charcoal Canister, 2. Charcoal Canister Filter, 3. Canister Close Valve, 4. Fuel Tank Pressure Sensor, 5. Purge Control Solenoid Valve, 6, Wiring and/or connector/connections between them and the ECU. If you wish to trust the computer's diagnostics, then replace the canister close valve (after you have inspected the Evap Charcoal Canister's air filter and find no problems with restrictions of air flow). If the problem comes back, check the Purge Control Solenoid Valve and the operation of the Fuel Tank Pressure sensor - either one of those components, if malfunctioning, can cause a P0446.

Hi

Before you turn out the light you should have a code read carried out just to make sure nothing sinister is going on with the management system.

If the car is running ok then the code will probably either pertian to the O2 sensor, the EVAP system, or a drop in catalytic efficiency, but this isn't set in stone, just the most popular scenarios.

Very best regards
