Confirm my theory, if i replace the pre cat passenger O2 sensor these will all resolve? If i clear them they come back over time, about a week or so.

Car runs fine otherwise,

16519 - Oxygen (Lambda) Sensor B1 S1; Heating Circuit: Malfunction
P0135 - 35-10 - - - Intermittent
17536 - Fuel Trim; Bank 1 (Mult): System too Lean
P1128 - 35-10 - - - Intermittent
17538 - Fuel Trim; Bank 2 (Mult): System too Lean
P1130 - 35-10 - - - Intermittent
17536 - Fuel Trim; Bank 1 (Mult): System too Lean
P1128 - 35-00 - -
17538 - Fuel Trim; Bank 2 (Mult): System too Lean
P1130 - 35-00 - -

I would think so. I just had to replace mine. Got it off Amazon for around 80$. Bosch brand. Works great. Mine would read rich once the car warmed up, so it cut fuel. Never threw a code for me though.

Exactly. Clear them for now... drive a bit and if they come back right away then replace the sensor and clear again. The codes wont come back again as long you correctly resolve it but the heating circuit code makes it pretty clear that the sensor is toast.
