How many O2 Sensors
 

How many O2 Sensors are on a 2008 Sebring 3.5L V-6 Limited convertible? I have an engine light on and parts store said it's an O2 Sensor.

If the parts store had given you the complete code, it would have told you the position of the offending sensor. There is one in each bank exhaust manifold and one, POSSIBLY a second further down the exhaust system.

There will be one upstream and downstream of each catalytic converter. The code should point to the specific one. You would do well to replace them in pairs, both the upstream and downstream sensor. They work in pairs, with the computer comparing the upstream reading to the downstream reading to determine if the cat is doing its job correctly. As they age, the computer takes the aging into account. If you replace only one of the pair, it may confuse the computer.

OK, thanks.After looking up the part numbers, It looks like all four sensors are the same part number, Right?
