What are some of the 2010 mazda 3 oxygen sensor problems?

If an oxygen sensor in Your 2010 Mazda Mazda3 isn't registering voltage within normal operating conditions, it will trigger a P0130 trouble code. It's actually a very common code, and in most cases, not too expensive to fix. An OBD-II scanner is used to determine which sensor needs to be replaced. For example, Bank 1 means there is an issue with the sensor in the first cylinder, so You would need to know the firing order for Your vehicle to change it. Also, Sensor 1 is a pretty common one. It's the first one in a line of several that run from the exhaust manifold to the exhaust pipe. Common symptoms of a bad O2 sensor include engine running rough, bad smelling exhaust, and failed emissions. The average cost to have one of these sensors replaced in a Mazda3 is $280 to $320, including labor.
