Re: Code Scanner
There are quite a few different codes for each oxygen sensor, no activity, heater circuit, and so on, but every code will tell the sensor-Bank 1 Sensor 1, Bank 1 Sensor 2, Bank 2 Sensor 1, Bank 2 Sensor 2 and if you have a 4.3 or 5.0 there is a Bank 1 Sensor 3 but no Bank 2 Sensor 2.
Then there are the lean/rich and catalyst efficiency codes that may be caused by a faulty sensor
The scanner used by AZ may be cheap, but it should give a code number that may lead to the sensor
