Recently I diagonis my car with a work shop, they find that my car has problem with air fuel sensor, they asking about $400, I finally find out where the sensor ion my car, I know that it is not a hard job to replace that one, I defetly change that one. My question is when I replace that sensor, we need any further testing or diagonis on that air fuel sensor. Or just turn on the engine only. Plese give me awright answer for that one.

They both show the air/fuel ratio heater circuit malfunction. Before you replace the front oxygen sensor, you need to check the circuit/wiring from the sensor back to the computer. Here is the diagnostic.
