What causes a lean reading on an O2 sensor?

High (O2) content in exhaust equals a lean reading also causing engine misfires. There are also some other possibilities such as an internally leaking EGR system. This will typically set a separate code. A leak in the exhaust system before the (O2) sensor will also cause incorrect readings.
