You may have a faulty O2 sensor. Many auto parts stores will read your cars computer error codes for free, as a courtesy, with a hand-held scanner if you ask them. This would be your first step in determining the cause for the "Check Engine" light.
If it is an O2 sensor, sensor 1(upstream sensor) can be accessed from under the hood on the drivers side, just after the exhaust manifold, and before the catalytic converter. Sensor 2(downstream sensor) is after the converter, and can be seen from this location, it can be accessed from under the car. I highly recommend purchasing the socket made for sensor removal.(About $10.00) Spray with a bolt loosen-er, and make sure to let the car cool down completely before attempting removal!
The sensors are a little over $100.00 each at a parts store, but if you look around the internet you can find them for less than half that price.

    The check engine light can often be triggered by not securing your gas cap tightly and will not reset until the vehicle has been restarted a dozen or more times. In any case, the cause can be determined with the above mentioned hand held scanner. The check engine light can also be reset with the some scanners.

2001 kia sportage will brake lit switch cau the truck stall whil driving

Yes, If your idle RPM is too low it can kill the engine due to the high current of the brake lights will cause a stall.

Most cars use an RPM idle of 750 to 775 RPM. Check your manual then increase your idle a little.
Hope this helps.

The Egine Lights of my Kia Sportage 1999 is always on when i am driving and it wont turn off. Some mechanic recommend that i must replace the cat convertor and oxygen sensor can that be true before i buy...


When the check engine lights comes on there are codes stored in the ECU module (car main computer.
To know what must be replaced you need to find out what codes are stored in the ECU.
Post 1995 codes adhere to OBDII standard (see here: Kia OBD-II Trouble Codes). The codes can be retrieved connecting the ECU to a code scanner (like this:Actron CP9575), and performing a scan.
If you live in the US, code scanning can be done for free at the nearest Autozone, otherwise you can have a code scanning done at your garage for a small fee.

Regarding the mechanic's suggestion of replacing the cat convertor and oxygen sensor, that is probably based on testing. If the mechanic has checked the emissions, and emissions are hight though the engine is OK, then it may time to replace the cat converter. The mechanic can also decide to replace the cat converter if the part is not in good shape.

If the decision is based on an O2 sensor OBDII code,before replacing the sensor better having a quick look at emission and engine.

The best way to proceed is generally determined by the code returned and by the checkup of state of the engine, O2 sensor, and exhaust system.

You'll need to have the car scanned and get the OBD II P Code. Most auto parts store will do it for free. That will tell you why the light is on.

Got a code p1624 on my 2000 kia sportage with is it and what does it do.

Per the manual it states: MIL Request Signal from TCM to ECM. Which means there is a signal fault between the Transmission Control Module to the Emission Control Module. If you can, take it to the dealer for repair as they have the parts on hand and are most familiar with their vehicles.
Good luck to you
