Check the wiring from the sensor to the PCM. Make sure there are no breaks, cracks etc that will cause the voltage to report incorrectly.

After replacing the sensor - it is mandatory to let it calibrate to the PCM.

Meaning it will take 5 cycles... engine to operating temp, and cool down for the PCM to calibrate.

Wait about 3-4 days for the calibration to take place, then erase the codes.

If they come back - please re-post and I'll be glad to continue troubleshooting.

Don't forget to write down the exact code you are getting. Some codes mean different things on different vehicles.

Was there a problem with the 2006 kia sportage timing belts

Not really, as it doesn't show in results. Recommended that you change them at 100k miles, they break at 112k. The engine is an interference engine, so a broken belt equals bent valves.

How to change plugs on 02 kia sportage

  • 1

    Keep a regular schedule for inspecting the spark plugs on your 2002 Kia Sportage. According to the official 2002 Kia Sportage owner's manual, spark plugs and ignition wires should be inspected every two years or 48,000 miles, whichever comes first.

  • 2

    Let your 2002 Kia Sportage sit for a few hours before opening the engine compartment. You want to make sure that the engine is cool before you begin working on it.

  • 3

    Pop open the hood of your Sportage and locate the ignition wires, which will be attached to the top of your engine. The 2002 Kia Sportage has a four-cylinder engine, meaning there are four spark plugs each attached to an ignition wire. The ignition wires run from the engine to the fuse box, which is located in the left side of the engine compartment.

  • 4

    Inspect the ignition wires of your 2002 Kia Sportage. These wires will need to be replaced if they appear worn.

  • 5

    Disconnect the ignition wire to your spark plugs. Grab the rubber boot located near the base of the wire and pull upward instead of yanking on the wire. Remove only one wire at a time, or mark the wires with a colored Sharpie marker before disconnecting all of them. Improperly reconnecting the ignition wires can seriously affect the performance of your Kia Sportage.

  • 6

    Attach the spark plug socket to your socket wrench. Use the socket wrench to remove the spark plug from the top of the engine's cylinder.

  • 7

    Inspect the spark plug. There will be some soot, but if the spark plug is completely covered in soot, it needs to be replaced.

  • 8

    Position your replacement spark plug in place and secure it with the spark plug socket on your socket wrench. Be careful not to overtighten the spark plug after it has been snuggly fitted.

  • 9

    Position the rubber boot of the proper ignition wire in place above the spark plug and insert it with your hands. Close the hood of your 2002 Kia Sportage

    Does the 2002 Kia Sportage have an noninterference engine or does it have an interference engine?

    2002 Kia Sportage 2.0L dohc, is an interference engine, will cause piston to valve damage, Kia recommends timing belt replacement in California every 90,000 miles, except California every 60,000 miles, hope this was very helpful.

    Hello mrhbollinger: My name is Roger and I will help you. You did not say Exactly what happened. If you were driving down the road and the engine died? Or if you pulled up to a stop and the engine died? I would check a few things first. Does the engine have over 60,000 to100,000 miles on it? If so I would look at the timing belt as a problem. Check the compression Compression should be around 160 psi. Any thing less then a 100 psi. the cylinder will not fire. Also keep in mind that this engine is a interference engine. This means should the timing belt break. The engine will suffer severe internal engine damage. By that I mean any valve that was open when timing belt broke will be damaged. Piston damage will also accrue. If the timing belt is not th problem I would look at the fuel system you should have 43 psi at the test port.I would also test for spark at the spark plug wires. If you have none and you check spark first. Check compression to make sure the timing belt is not the problem. If you remove the oil cap and can see the the camshaft. Have some one crank the engine over. If the valves do not move the timing belt is the problem. Should you need further help please just ask Thank You for using Fix Ya. Roger

    I had the oil changed and the manual transmission fluid changed 2-3 days ago. I noticed leaking today on the right front tire side. A few hours ago it died. Still has power (lights, radio) but...

    I don't believe the transmission fluid being changed would have anything to do with the engine being dead. You could have a tranny with no fluid in it and the engine would still run. Wondering if your engine oil got changed correctly. I would pull out the dipstick for the engine oil and see how much is in there. If this is an error from an oil change place that has caused your engine to die because of their negligence, then you may have a legal issue on your hands. Good Luck.
