3.0 engine? The code P1135 showed up. And it said its the air fuel sensor heater (bank 1 sensor 1)...
1st Q: Is the air fuel sensor heater the same thing as saying the air fuel ratio sensor?

2nd Q: I recently already changed the oxygen sensor...and I spend around $200 to change it, is the air fuel ratio sensor the same thing as the oxygen sensor?

3rd Q: I have been told that the oxygen sensor looks the exact same thing as the air fuel ratio sensor, and I wouldn't be able to tell the difference between the two.
Where is the location of the air fuel ratio sensor (bank 1 sensor 1)? I've been searching online for some answers, and I have seen people's responses as before the catalytic converter.

4th Q: What is the location difference between the air fuel ratio sensor (bank 1 sensor 1) & the oxygen sensor (bank 1 sensor 1)?

Hope someone can really help me on this question. Because the air fuel ratio sensor is another $250 if I buy it at the dealer.

The sensor heater element is electric and is used to heat the sensor as quickly as possible when you cold start the engine. But then the sensor element itself takes over to talk to your computer once the engine is hot. So you don't need the O2 sensor heater element except when the engine's cold. You can just keep driving and not replace it until you need to pass a State emissions inspection.
