Two, one upper one lower.
how many oxygen sensors does a 2003 kia sedona 3.5 have
two one upper one lower
The TCM is the transmission control module and it has nothing to do with oxygen sensors!
The oxygen sensors are located in the exhaust system on either side of the catalytic converter.
There are 2 o2 sensors. One directly in front of the engine on the exhaust manifold (upstream), and another underneath the car, after the catalytic converter (downstream).
There are four oxygen sensors one on each exhaust manifold or bank of cylinders and one after each cat for both banks of cylinders
All O2 sensors are located somewhere on your exhaust pipe.
The 2001 Kia Sportage has 16 valves.
The 2001 Kia Rio has 16 valves.
The 2001 Kia Optima has 16 valves.
in the exhaust manifold
it should ,they are both the same engine,the only thing that would hesitate me would be the connection harness to sensors and computers.
