    '05 Tundra 4.7L threw code P0156. I replaced the Bank 2 Sensor 2 with a new Denso and did a reset. Code threw again. Is there a chance that the new sensor was faulty? The voltage tends to stay high (.8-.9)on that sensor while in operation. I say tends because it does not fluctuate as much...

    Hi Guys, Newbie poster here but I am frustrated and not sure what to do next. So I am original purchaser of a '06 Sequoia. 144K miles now and no issues BUT about 3 years ago, I started getting a CEL. It was the P0430 error code. It was very sporadic and I finally narrowed it down to a couple...

    Instructions on How to Replace O2 Sensors on a V6 Toyota Tundra 2002 (2000-'06)P1135 So after a lot of internet trolling, I finally replaced my front O2 Sensor (A/F Sensor : Bank 1, Sensor 1 : P1135/P0135) this weekend!!! It has been bad for over 4.5 years. When it first went out, I had the...
  5. Intake and Exhaust
    Ok, so I have a check engine light. Got it checked out, turns out it was the O2 Sensor, Bank 1 sensor 2. The one just before the exhaust. I replaced the sensor (pain in the butt 04 Tundra), had the error cleared and the next day the light came back on. Thoughts
  6. 1Gen-Sequoia
    Does anyone know for sure what a P2241 code is on an 05 Sequoia? The CE light came on the other day and when I checked it, it came back with this code. My book didn't have the code listed, and searching on the net didn't come back with anything specific to the Sequoia. I did find other Toyota...

    Hi, I am new to the forum. I have a 2004 Tundra Double Cab with the 4.7 V8. A year ago, the trouble code for the front O2 sensors came on and these were replaced. More recently, I am getting a P0430, which is, as I understand it, the passenger side Catalytic Converter system efficiency. My...
  9. Highlander
    I posted last June at 186,000 miles: My ’03 4 cylinder Highlander has been throwing intermittent P0420/P0430 codes for over two years. The CEL came on last August and stayed on for good. I ignored it for nearly a year after speaking with a Toyota mechanic who said that it could be the O2...

  14. 1Gen-Tundra
    My '01 Tundra's check engine light (CEL) came on a few weeks ago. I tested the OBDII at Autozone and the oxygen sensor was bad as I suspected. I purchased a universal sensor because I am cheap and I have the "I think I can fix anything" complex. I replaced it, reset the ECU by pulling the...
