My 03 sienna threw an ECM code for the bank 0 O2 sensor. Not a big deal I think, though 60k miles seems a bit young. So I go to my local national auto parts chain and get a price... $302! Huh? For a single 02 sensor? It's a 4 wire O2 sensor, and I have no problem soldering. Anybody know why that Toyoyta part might be so pricy? Is there something special about it? I don't mind adapting the factory harness to a generic sensor if it will save me $200. | ||

You may find that a Factory Toyota part is less expensive than an aftermarket. | ||

Thanks! I'll check. | ||

Air fuel ratio sensors (bank 1 towards firewall, bank 2 towards radiator) suggested list $206.86. Downstream O2 sensor $127.04. A/F sensor replacement not uncommon replacement items. | ||

That sounds much closer to what I expected... Ping me offline if you are associated with a chain that is somewhere near being between Dayton and Lebanon Ohio  I believe the code read "upstream bank 0 02 sensor". I'm guessing that it would be on the header on the firewall side, and that bank 0 means there is only one of them, or if there are two of them its the one upstream of the catalytic converter. Figures, it can't ever be the easy one to get out  | ||

Reepicheep my 03 stratus threw an 02 code and the part was like over $200. I bought a universal 4 wire sencer at Advance Auto for about $69.It came with every thing to give a waterproof splice, been on 2 years no problem.When my slave cylinder for clutch went out.Dealer only idem $69 Drivewire.com had one for $29 and about $5 shipping, got it next day.Good luck  Glenn | ||

The terminology is usually bank 1/sensor 1 or bank 2/sensor 1 to indicate sensors in the manifold pre-cat. The bank that the number 1 cylinder is in (the farthest forward) would be bank 1, bank 2 the opposite side in a V motor. Sensor 2 is a downstream unit, there could be 1, 2, or none of them. I your case there is 2 upstream A/F sensors and 1 downstream O2 sensor. The prices I quoted are Toyota suggested list prices (who I work for doing wholesale parts) but everybody sells them for what ever they want to. I work in California (although I lived in Vandallia a lifetime ago) so I'm a little ways away though. I'm not sure what is meant by bank 0 though, get an explanation of that. Watch the quality if you get an aftermarket unit, some are great and some are real Mickey Mouse bad. (Message edited by bertman on January 19, 2007) | ||

The aftermarket one I got was Bosh the main suppler of 02 sensers | ||

Thanks! Something does not add up then, I'll get another scan and an independent opinion. I may try the universal, but I will make sure its a know good brand (like Bosch or Denso). Great info! Thanks! | ||

Dug out my notes... It was bank 1 sensor 1 O2 sensor. Nice... sounds like it is even the easy one to get at. Thanks all... | ||

Just an update, not that anyone probably cares at this point... But I have this closure thing The part was $220 out the door after tax. Ouch. It's a wideband four wire sensor... the code was P0135. Aftermarket was $180+, so it did not make sense to not get the exact right part. That is the bank 1 sensor 1. My Toyota dealer indicated that is the furthest forward one, but further googling seems to indicate that they were wrong. It seems to be the one against the firewall, not the one that is easy to get at. That'll be an adventure no doubt. Harbor Freight has a web sale on their OBDII / CAN scan tool.. a $79 part (decent deal) for $39. Print out the page, take it to your local shop, and they will honor the price. For $39 its a pretty cool tool. I'm gonna wait until it warms up to crawl under there. It's the internal heating element that is toasted. So I have a good wideband O2 sensor with a broken heating element... so I got to buy a $200 15 watt heater |
