2000 Kia Sephia Ls Automatic (Engine Lite On)

I bought a 2000 Kia Sephia LS Autoamatic from a Used Car dealer in ASIS Condition with no Warranty.

The Vehicle had 57K Miles and , I took it for a test drive and it was fine. I bought this car 10days back.

After driving for about 15 Miles, the O/D light came on immedietly followed by the Engine light. I took it to the Used Car dealer and he said , it was not a major problem and it may have come because of less Oil. He poured some Oil and disconnected the Battery and reset the Code.

The lights again came back after 10miles. This time I took it to the Kia Nw Car dealer for Oil Change. I also wanted to know about the warranty and other details about the car. The dealer initially told me that the vehicle may have 5yr/60K basic warranty and PowerTrain Warranty which may not be transferrable since I am not the first owner.

However he came back and said that I have 3yr/36K basic warranty which had expired and she confirmed that I have 5yr/60K PowerTrain Warranty. That meant I had 3k and 3 months left on My PowerTrain. They changed the Oil and told me I have to take an appointment for the O/D light and Engine Lite Problem.

Since I was worried , I took my car to Autozone as per my friends advice to diagonize the problem.
The diagonized it with there meter and come up with the below problem
1. P0717 Speed Sensor Problem
2. P0733 Gear 3 Ratio Incorrect
3. P1624 They did not the description and ask me to take it to the dealer
4. P0732 Gear 2 Ratio Incorect

I am not sure what to do now. The car seem to drive OK. I just bought this car 10days back taking a loan and now I am in a big fix

Please advice me what to do on the below

1. Please give your comments on the above problems diagonized
2. Will I be getting the 5yr/60K warranty??
3. If the transmission is having problem, will the dealer replace it and how much I will be charged

its not a major thing. i've had this happen. i dont remember what the fix was but it was a sensor or something small like that. dont worry you'll get your money out of it.now that i think of it im 70 percent sure its the speed sensor and it was like a 200 dollar fix but diy is probably less than 50. 12k and i think it was done twice. only recurring problem i had. make sure its up to date with recalls

Excellent answer from you... I took it to the dealer and he said one of the Speed Sensor connectors had gone bad. He changed that and all the coded went away. Ofcourse it is the dealer and he charged $170.

I have another problem. This time I have code P0422 (P0422 Main Catalyst Efficiency Below Threshold, Bank 1) . The engine lite is ON intermittently.The autozone rep told it may not be a major problem and some cleaning may be required.

Is it something to do with the catalytic converter??? Please give your comments on how to fix it.

im not sure. may be o2 sensor. doesnt sound major. was it bought at a kia dealer

Can you or anyone tell me which connector went bad? I'm trying to figure out where my problem might be and I have already replaced the sensor itself. If this is a chronic problem area, it might be the same one or at least I'll know where to look.

simple fix speed sensor worse case transmission
regardless take it to the dealer and ask if your car still under warranty by date you still get 5 year 60k miles on it
