    Hi, I'm new to this forum. I have a 2002 Tacoma 4x4. I love this truck, but it pulled a P1135 code. I replaced the bank 1 sensor 1 O2 sensor last Sat. and the check engine light went out. Tonight while driving home the check engine light came back on. Does anyone have any advice. I'm not sure if the Toyota dealer will warrant the O2 sensor or not?

    check your conections and terminal tension.other than that it is always possible to have a vaccum leak.look for these after the maf sensor.you can also check the circut for a possible wire broke and the insulation rubbed through and grounding out.

    Check the wireing on the Sensor you replaced. Make sure the connection is good, and no wires are broken or damaged.

    Thanks to those who replied. I opened the hood and discovered a hose off at the air filter box. I replaced the hose and reset the check engine light and so far the light has stayed off.
