Ok so i know this issue has gone on for awhile but i replaced the front o2 sensor, and still had problems so i assumed that the rear sensor is also gone, well the four codes pulled are
130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
137 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)
141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

Well i really have no idea what to make of this don't flame me please but what needs to be done to get these codes fixed. And can someone please explain what is Bank | Sensor??

it's either the O2, or the cat, or you have a leak somewhere in there!


also, what kind of O2 sensors are you using? OEM i hope!

Yes. I bought one on ebay that was a volvo one, but volvo uses bosch so it's a bosch sensor. But what about the low voltage and the bank sensors, i'm not familiar with that.

BUMP

Still don't know what bank 1 is but i'm assuming Sensor 2 is the aft sensor.... and there is not a "circuit" that i'm aware of...

Replaced front o2 sensor car still runs bad and has poor acceleration. I'm going to replace rear o2 sensor but I fear that will not fix the problem.
Help would be appreciated
