Toyota Repair: OBD 2 Code P 0135, toyota service manual, air fuel ratio


Question
I have a 2002 Tacoma EXT Cab Trd 3.4L V6. The check engine has been on ever since I bought the truck.  The guy at the car lot said it was an O2 sensor but at the time i didnt have the money to replace it.  I replaced it over this past weekend, went to Advance to have the code erased.  I made it about 10 miles and the cel came on again. It stayed on for a few minutes then went back off for a few minutes more then came back on again and has been on ever since.  I had the codes checked and it came back with P 0133 and P 0135. I have checked the resistance on the sensor and it is good, Ive checked the EFI Main relay and it is good, and Ive checked the PCV Valve and hose and all looks good there.  I did this per the Toyota Service Manual.  Im at a loss as to what this could be any help you can give would be greatly appreciated.

Answer
Did you mean P1133 and 1135? p0133 and 135 are not listed . The p1135 and 1133 are air fuel ratio sensor codes for this sensor which is located just before the cat converter, 1133 is for the control circuit malfunction and 1135 is the heater circuit malfunction , replacing this sensor normally fixes this.
