Question about 2007 Kia Sorento LX 4x4

4 Answers

I have a 2002 Kia Optima V6. Automatic When driving at speed limit its almost like someone steps on the brake and lets off real quick. The engine light comes on. It drives just fine till you stop. When pressing on the gas to take off its like youre riding the clutch past 1st gear and it feels like the brake is on at the same time. However, when it reaches at least 20mph. it drives fine. What could be wrong?

    I have an 06 and am having to get a new throttle body and dealer told me they are doing alot of these on Optima and Sonata. Hopefully this will turn into a recall item and I can get reimbursed my 500 dollars.

I took a bmw in for a smog test and it failed because the test engine light was on, I took it back to my house and read the owners manual and got the light to go out, There was nothing else wrong, I am a mechanic I had no dout that there was anything wrong. I took it back in for smog test and it passed flying colors.lousy test engine lights. the computer should be made to corect its self. and do a self fix, the only reason for the tast engine light was to notafy you of the next service.

This vehicle has a RECALL Campaign for the Above mentioned Problem as well as ECM issue. I would call the local dealer and see if your vehicle qualifies.

Hi there, the crankshaft sensor sounds like its trying to go out on you. see it picks up a magnetic signal on the crankshaft to control the timing and if its bad then produces the symptoms your describing. i would defineatily go to autozone or a shop to find out what code made your check engine light come on

Check the condition of the trans fluid. If it is black the trans is proably worn out. You could take it to a kia dealership and ask them to reset the adaptives on your transmission.

Where is ignition distributor engine speed input circuit located on 2002 Kia optima

Well the 4 cyl engine uses a coil for each cylinder, and the 6 cyl uses one coil for all 6. Both systems use signals from the engine computer to fire the coils. So the RPM circuit would involve the engine computer. No distributor is used.

Input speed sensor

The input shaft speed sensor is located on the side of the transmission by where the engine "inputs" power to the transmission (via torque converter), thus rotating the input shaft.
The output speed sensor is located by where the axles attach to the transmission, and measures the speed that the transmission "outputs" to the axles (which make the wheels turn) and that data is also used for your speedometer reading.

Where is the vehicle speed sensor located on a 2002 Kia Optima V6 2.7L

Should be mounted on the transmission. Go to PEPBoys or CHECKER or other parts store and look at the replacement part. Then you should be able to recognize it under the hood.

2002 kia optima slipping into 3rd and 2nd gear while driving

UPDATE! ! ! Fixed this problem! YES ! ! ! The speed sensors was all that needed replacing. NOT ANY SOLENOIDS ! !. Two of them cost $160 and it solved the problem! Do not buy from the dealers. An after market version is available for $50 each. I was forced to buy dealers.
