The background.


I had a P1283 code So I decided to change out Bank 2's sensor because the voltage valus were a little high. (Look at the attachment #1)

The Questions


So what are your voltage values for your o2 sensors? Before a cold start and after your car is idling.

If these are wideband sensors shouldn't the voltage be a little higher? Around 1.5v atleast. (Look at the P1273 & P1283 troubleshooting guide link below)

Why is the new Bank 2 o2 sensor voltage higher compared to Bank 1? But not high enough to be to be in the wideband range?

Did infintit just swap out the connectors without updating the o2 sensors? Wideband is suppose to have higher voltages correct?


Attachments

#1) This was my before the new o2 sensor with the P1283 code.


#2. After replacing my o2 sensor with a 2005 one. I got these readings before a cold start and it makes no sense that bank 2 is a little higher.
Note: I purchased one for a 2004 and the connector did not match up at all


#3. Here's a log after driving around at a idle.

And when reving my engine around 2000rpms I dont get around 1.5v from Bank 2.

Here's the o2 sensor I purchased. Should I've gotten bosch instead?
Denso 234-5061 Oxygen Sensor (Air and Fuel Ratio Sensor)

 

Okay So I just plugged in brand new Bosch 15667 sensor(For 2005 G35). to see if the readings would match up on bank 1 and bank 2.

It looks like Bank 1 got a reading of .800v on idle.
And Bank 2 got a reading of 1.275v on idle.

Note: this is just open air from the engine bay.

Any idea's?
