Hello members,
My OBDII light is steady, I checked the error code, it is P0139 which means seņor 1 bank 1 is faulty. I tried to locate it but couldn't. Can someone help to locate it. And where should I buy new one ( online and in-store). What socket wrench would I need? I live in Canada.
Another question is regarding light bulb in transmission ( P R N D D1 and D2). It's not turning on fro where I can buy this. Thank you.
Ben

For the best price: 1) Get the part number for the correct sensor from a dealer parts department using your VIN; 2) Cross-reference the Toyota part number to the DENSO part number at the DENSO website:

3) Search for the DENSO part number at Amazon.com and buy it there.
Toyota 4-cylinder sensor 1 is usually on the top of the exhaust manifold at the front of the engine near the radiator. They are most commonly held in place with two 10-mm bolts on a flange. You will probably have to seriously heat the exhaust manifold with a propane torch just before removing the bolts, after liberally applying some penetrating oil (such as PB Blaster or Liquid Wrench) and letting it soak in for a few hours. WD40 is not a penetrating oil, so don't bother with it. If you break those bolts, you are in trouble.
Buy the bulb at a Toyota dealer parts department.
