I need to know how much will a throttle sensor cost to fix a kia optima
NO They are not the same.
the lamba sensor is located inside the maifold
My mom has the same Kia and they replaced hers for free because it is part of a recall. You can google the recalls on line and then call the dealership and give them your VIN number and they will tell you if yours can be replaced free of charge.

the oxygen sensor is on the exhaust manifold, to get to it you will need to take off the air intake box under the hood...you will see the sensor sticking out the manifold in plain view, against the radiator
