There are two separate sensors in the coolant flow. One usually has just one wire and is for the dash gauge. The other has two wires and tells the computer how warm the engine is to control fuel mix. Sounds as if your dash sender may be bad. Buy the part from parts store and ask if their parts locator system can show you where it is.

Before replacing anything, check for failed engine ground. If using jumper cables, use only the black cable, do not connect the red cable. Connect one end to the battery negative terminal and the other end to anywhere on the engine where you can find clean metal, even if you have to sand it clean. The try starting. If it starts, install permanent new secondary ground from negative battery terminal to an engine bolt. If no start, then remove starter with solenoid attached and have it tested at an auto parts supply store. If it fails the test, replace it. If passes the test, reinstall, then set about cleaning all electrical connections, that is disconnecting, sanding or polishing, applying a thin layer of dielectric grease and reassemble and tighten. Do this one by one with battery terminals disconnected, tracing from the solenoid, back to starter, back to ignition switch to master fuse block and back to battery positive terminal and on negative side from batter to ground. If you have an oscillating tool with a miniature sandpaper holder, it works wonderful for polishing electrical connections. If all connections clean and tight and still no start, try bridging the solenoid to eliminate the key switch and see if it properly operates. If so, then the key switch has just been identified as the culprit.

First I would check your radiator fluid level, sometimes being low can have this effect. Usually the rear heaters sit at a lower level and so keep working. If that is fine, then you probably have an issue with the diversion door or controller that controls the hot/cold mixture.

If the heater hoses for the front heater are getting hot, it could be a blend door problem under the dash.

It could be a corroded ground cable. follow the neg cable from the battery and see where it bolts to on the body remove the cable and clean and sand the area reattach the cable and spray some battery terminal protector on it. I've seen this a lot on older sorentos

That code means incorrect purge flow. so you have some problem in the evap system. either the purge valve is stuck open or closed, you have a restriction in the evap line or an electrical prob with the purge valve. ex. the valve dose not have power or a bad ground.

it's possible. The water can cause misfires in the engine. when the light flashes that means you are causing damage to the engine.

The CPS is located under the timming cover 4 small bolts remove the cover and the sensor is viewable 2 bolts have to be loosend and the wire leads up to a dual connector on the left side of the engine

I have an 2002 Kia sedona the code p0304 means an 4 cylinder misfire and also the wiring and plugs.I noticed an while back that when I press the gas smoke will come from my tailpipe and now my van is hesitating to go and it stumbles and the check engine light is on,I have the same code p0304.

Remove the headlight assembly. Just remove the 3 bolts with a 10 mm socket and pull it out so you can disconect the wire harness. After that pull the whole assembly out and unscrew the bulb cover. The bulb is held in with a spring clip.

First thing to do is get underneath and check the linkage, make sure everything is connected.

check the alternator.

There should be a fuse sticker located on the opposite side of your fuse access.

The firing order sounds strange but if you are correct then you are right in saying that number 2 cylinder will be down with inlet valves open when number 1 cylinder is at TDC.

Typically they are located near the oil filter. Your oil filter should be located under the passenger side of the engine. The oil pressure switch (if you have an oil light) or the oil pressure sending unit (if you have an oil pressure gauge) should be right above it.

Low battery or bad connection to battery or starter

Low battery or bad connection on battery or to starter.

it is a big job you have to remove all the front part of the engine it runs off the timing belt so you should replace it at same time if you are a mechanic at heart it can be done but if not there is a lot to remember if you have a lift it is better if not well jack the van up and remove front right wheel and remove plastic cover to give access to timing cover as well the crank pulley then remove the belts and so on then put a block of wood under the oilpan with a jack under it you have to remove the upper engine mount and so on to get the covers off now you should see the timing belt you have to align the marks on the two cams on each side becareful they spring back when removing the belt now check the crank mark for alignment now there is a plunger tightener you have to push it back and put a pin into the locking hole of the plunger if not remove it complete and put in a vise close the plunger til the alignment hole lines up and use a nail or drill bit 1`8 inch drill now go back and lock your cams from moving the dealer has a special tool or auto parts but worst off you cant get them you can take the belt off but make sure when put back that the cams are aligned if not you can scrap the heads cause the valves will hit the pistons now everything off you should see the water pump and the bolts to remove it in the back there is a tube witha o ring becareful when putting it back use some grease for the pump to go in easier good luck its a 4 to 8 hrs job if not trained and not equipped could be longer

this indicates a miss fire on cylinder #5. can be caused by bad plug, plug wire, ignition coil, fuel injector problem either dirty or electrical, vacuum leak at the intake runner, a compression problem.
