Yo Nimrod, this fix your issue? I have the same problem, P1135, replaced the O2 with a denso, new plugs/wires, clean maf, cleaned TB and took apart IAC and cleaned that out, seafoam, new fuel filter and even went as far as a new ECU and im still throwing the P1135 CEL. i have a flow master 40 with stock piping and stock K&N intake filter with elbow mod. Help Help!!!
I assume you checked these before getting a new ECU but I have to ask.

I didn't check it because im not an licensed mech or electrician. Took it to a trusted electric mech and he told me the sensor checked out fine, even bought another denso oem replacement o2 and checked the resistance there and it matched the new o2 i put in. thats why i bought the used ecm because he told me thats was the next step...

Two wires need to work--only one goes to the ECU. So why is changing the ECU the next step? Especially since it is not cheap...and didn't work anyway.

you did nothing for a p1135 code
the p1135 is the air fuel sensor heater in front of the cats, not the
o2 sensor behind the cats. at your mileage the most common cause
of p1135 is a plain old, used up, a/f sensor. and you need toyota OEM only, no
screwing around with aftermarket. make sure you are getting the right part replaced

you keep saying O2 sensor. if you really replaced the o2 sensor
you did nothing for a p1135 code
