  1. Thanks for the reply fidgits - I actually have an update on this quest for the 02 sensor. ====== I managed to find some another useful site on the web and the discussions held there led me to finding this O2 Sensor - Bank 1 Sensor 1 on my engine type = 1MZ-FE. This other site is: http://about.com/ Search for "O2 toyota" or code "P0135" and a whole list of discussions come up. I pieced together my answer there. ====== Anyways - back to the actual location of the O2 Bank 1 Sensor 1 on my engine, it's physically located at the "back" of the engine when you lift open the hood. The "back of the engine" is the side closest to the firewall/passenger's compartment. It's not easily assessible at all from the top - as you're looking into the engine area. I can only see it by standing on the driver side and peering into the lower back side (between the engine and firewall) of the engine. It looks like the shape and size of a spark plug with a cable attached to the end of the unit. The cable leads to a connector - which needs to be detached in order to test the resistance. Inside the cable - there are 4 wires. The only way I was able to reach this O2 sensor is to get "under" the car, lifted on ramps. And then - you need a rather small sized arm to sqeeze in - to reach and remove the sensor. Also - since the sensor is attached to the exhaust-like pipe - it's normally extremely hot in this area. So - the sensor was almost fused tightly together in the socket. I had to use WD-40 and other "liquid-wrench" - rust penertrating type spray to loosen it. I struggled for more than an hour with an adjustable wrench before it finally came loose. I measured the resistance of the O2 sensor and it read 2.5M ohms. The spec book said it should be between 11 - 16 ohms. So - it's definitely defective, which will need to be replaced. It's not what I would recommend someone doing it themselves - because it was quite a struggle to physically get access to the O2 sensor unit. Unless - you're really determined to save (and I'm just guessing - $150 parts and $200 labour) - it's not worth the hassle. - I was only determined to do it because people said to leave it for the "pros". Anyways - I hope someone else will find this experience useful. mikeFromOttawa =================
  2. I have a Solara 2000 V6 - and got have the code of P0135. So - I need to replace the O2 Sensor - Bank 1 Sensor 1 - too. Would you know where it is located on my engine? - It's a 1MZ-FE engine. I've posted this message on the Camry section too. Thanks mikeFromOttawa ==============
  3. Hi, I have a Solara 2000 V6 (Engine = 1MZ-FE). The Check Engine lamp came on. Using my OBDII Reader -I got a code of P0135. Then I checked the shop manual - and P0135 means a possible faulty "Heated Oxygen Sensor - Bank 1, Sensor 1). So - I need to verify if the resistance for this sensor is between 11-16ohms. My question is: where is the Oxygen Sensor for "Bank 1, Sensor 1" located? The diagram in the shop manual is really not clear and I could not find it in the Haynes manual neither? It's supposed to be connected to "Cylinder 1" - which is on the passenger side - closest to the firewall. But I can't seem to find it on my engine! :( Any comments or suggestions will be really appreciated. Thanks. mikeFromOttawa BTW: I can see from the diagram that the other oxygen sensor for Bank 2 - Sensor 1" is located in the front of the engine - near the exhaust manifold.
