20 Most Recent Hyundai Motor 2002 Sonata Questions & Answers

Question edited for clarity. Question moved to model category from Washing Machines! Is the car running okay? If it is, don't worry. Makers make wiring harnesses for all variations of a model and the often have spare connectors with no mating connector for it. It is impossible to identify what they are, or were unless you have a factory wiring diagram for that specific vehicle. It it worries you, the dealership would know. ..

i just went through that problem

Evap canister / close solenoid and air filter $211- 230.00 in parts

$675- $71.00 at dealships for this small 30 minute task

If no check engine light Evap canister and air filter - fixxes problem 100 %
note:you may be able to get by just replacing air filter- works
rarely

if have check engine- close solenoid and purge solenoid may need replace- you local autozone- like autozone will pull check codes for free

the how to:

Jack car up in rear - behind right rear tire - canister -canister close solenoid & air filter are located in a plastic box with metal strap and one bolt.

Unscrew bolt everything drops down the EVAP CANISTER is held to plastic box by wirer tie . Remove wire tie and solenoid connection.
There is a small metal wire clip the holds the solenoid electrical connection together with a flat screw driver pry up the wire clip , off is okay too , ....it will go back on.

Once you have done all that you have full access there are i believe from memory 3 rubber hoses with clips ......Mark hose connects very important mark the hoses way the going on evap canister with color tape .

Next, remove whole assembly- the solenoid and air filter will come with the evap canister.

Now that have the whole assembly move to your work bench
look to see how the soleniod hook up to the canister and the air filter - now, disconnect the hose to black solenoid and remove the air filter which hook to solenoid and solenoid at same to ......

Next seperate the the solenoid and air filter- you should be air to put your mouth on solenoid and blew air in one hole and out the other- this solenoid is noramlly open- if air dosen't go threw is stuck closed and must be replaced.

same with air filter- this air filter are know for get plugged and should be replaced every 30,000 miles.

Also note: over fill you gas tank , at fill up - can cause the Evap to get liquid gas inside which cause the chorcoal in the filter to swell up and plyug the system up.------ you should when fill up stop pump gas after the auto pump click off on normal work tank and not try to top off you tank.

note: check with your deal for exact wieghts
weigh the evap canister - six pound - replace it- new one is about 4-4.5 pounds - it is just best to replace .The evap holds gas fumes then send to engine so that dosn't vent to

All parts are dealships only -

This is easy fix and normal, for gas fill problems

canister Evap 161.00
canister close solenoid 43.00 may or may not be used
air filter 7.00

not used in this fix- check engine fix use these parts
sensor price ?
purge valve 39.00
canister close solenoid 43.00

Most likely warped rotors. See this post http://ricksfreeautorepairadvice.com/warped-rotors-and-brake-pulsation

Ya, check behind the drivers rear wheel. There is a black box which contains the charcoal canister, filter, solenoid. You'll need to jack up the car, take that wheel off, mud flap and another plastic section inside the wheel well which will expose the hoses that run in and out of that box. . . . take note where all the hoses go. You'll need to remove the whole thing to get at the filter. The electrical lead that attaches to the solenoid has a unique locking clamp so its difficult to unplug, I opened the trunk and cut the wire where is runs into the wiring harness.(careful to leave enough wire to work with to re-connect it). The filter is hopefully the problem, its only around $10.

There is a special (proprietary) programming electronics 'black box' for the keyless entry system on all Hyundai vehicles for programming the remotes. This programming is stored in either the BCM (body control module) or the ETACS module (Electronic Time and Control System).

A clogged cabin air filter can cause repeat resistor failures. A bad blower fan can also cause repeat resistor failure. http://ricksfreeautorepairadvice.com/blower-only-works-on-high-speed/

replace the climate control module

Check oil level.

There is no such module, the fan is controlled through the central engine Powertrain control module.

Don't assume that a new battery is ok. Personally, I've fitted a new battery to later discover that it was that new battery at fault. However, it's quite rare .. If your battery is discharging very quickly irrespective of whether the engine is running or the car is parked - suspect the alternator. Inside the alternator there is a rectifier pack - diodes - if this fails it can allow your battery to discharge very quickly - sometimes within a minute or two, quite literally. If you can, disconnect the leads from the back of your alternator and charge your battery. Reconnect the battery but not the alternator. If your car starts and continues to start without the battery going flat - your alternator is at fault. The only other fault that can cause a healthy battery to discharge is a parasitic drain - something is remaining 'live' after the engine is switched off and draining your battery power. If you drive your car to a spares shop/auto electrician they will be able to tell you within a minute if your alternator is the problem.
