2006 Jeep Commander mileage: 26,500. I am having problems with an Oxygen sensor malfunction. I don't know if this is the only problem. Will I have to keep on paying for every fault finding repair even if that's not the one? Can you help with diagnosis and the best way forward?

It is possible that the oxygen sensor is faulty. The best way of finding out is to scan the computer for fault codes which will pinpoint the malfunctioning component. Having your own code reader is a great tool. Hand held code readers are available for about the same cost as scanning your car at a repair shop. Your check engine light will let you know every time there is a sensor that is out of range. These devices can also clear the code as well.
