I have changed my bank 1 sensor1 and bank 1 sensor 2 sensors. one upstrem and 1 downstream of the catylist converter. check engine lights gone until 100 miles later check engine light came back on. THe car is also smelling like rotten eggs that seem to point to a catylist converter problem. I'm wondering if I need to replace the converter and will toyota confirm its the problem even though the codes are saying sensor which have been replaced by my mechanic.

The coolant level in the overflow was on the low side was all. My brother in law (mechanic) has worked on the car since my wife got it. I recently inherited it from her & just noticed the level was down a bit. He hadn't mentioned anything about water pump leaks last time he checked it, back in the fall.

If you read the shop repair diagnostic manual section you will note that it does NOT say the downstream sensor is defective, only that the sensor output readings are out of range.
Since the sensor is less expensive, a lot less expensive, to replace I would also go there first. Non-California compliant catalyst are available (Ebay) pretty inexpensively.

Went to Toyota today to have then check out my sensor problem. I was hoping they would change out the catylic converter as it has been smelling like rotten eggs. The codes have been 2195 and 138 sensors. They want to charge me $1700 to apply the TSB 0114-08 which means they swap out the sensors and exhaust manifold. They said my Denso sensors which I bought from Rock Auto and installed by my mechanic were after market and they do not work in my car.
I called Denso and Rock auto and they said I have the same sensor that was Original Equip for my car and many times dealerships say that because there is another problem maybe the Cat. or Ecu or electrical and they don't take the time to look for the real problem.
If anyone has any insight on these sensor let me know. I'm considering selling the car as I'm not prepared to give Toyota that kind of money. This is a 2007 v-6 with 59,000 miles on it. Shouldn't have to be paying for the repair when Toyota has a design problem with there manifold. They new about the flaw while my car was under the 3year 36,000 warranty but of course if your check engine light comes on after the warranty period they won't warranty it. Bad bussiness!!!!
Need help! chuck

These codes are defined as P2195 TOYOTA - Oxygen Air/Fuel Sensor Signal Stuck Lean Bank 1 Sensor 1, and P0138 - Rear Heated Oxygen Sensor is producing excessively High Voltage.
The two codes are caused by the same problem. The problem is created by a leaking exhaust manifold gasket, or a cracked exhaust manifold; which allows air to leak into the exhaust system. When the oxygen sensors detect excessive air in the exhaust system; they send a "lean mixture" signal to the computer; which responds by richening the fuel mixture. The rich mixture causes a "rotten egg" smell in the exhaust. IT IS NOT CAUSED BY A DEFECTIVE CONVERTER, AND REPLACING THE CONVERTER WILL NOT CLEAR THIS PROBLEM. IT IS ALSO NOT CAUSED BY A BAD OR UNSUITABLE SENSOR.
Toyota redesigned the exhaust manifold to be less prone to leaks; which will solve this problem. They also had to redesign the air - fuel ratio sensor to work properly with the new manifold design.
If you do not want to spend the cost of a new exhaust manifold; you can address this by buying a used manifold from an auto wrecker or EBay.
If you do not want to buy a used exhaust manifold; you can have an independent mechanic or a qualified muffler shop thoroughly inspect the exhaust manifold on that bank and determine whether it is cracked.
If the exhaust manifold is not cracked; it does not have to be replaced. In that case; all that would have to be done to restore the car to its original condition is to install a new exhaust manifold gasket, and properly torque the exhaust manifold mounting bolts. The leak can then be expected to remain sealed for another 50,000 or so miles, and then repeat itself. But if the exhaust manifold mounting bolts are found to be loose; and the exhaust manifold gasket is not damaged; the problem may be able to be corrected by simply tightening the manifold bolts; and having them retightened every 3 years.
If the exhaust manifold is cracked; it would have to be repaired by welding up the cracked area. This procedure can sometimes distort the manifold, and make it difficult to seal properly upon re-installation. For that reason; I would recommend replacing the exhaust manifold with either another used one that is identical to yours; or with a used revised design from a newer vehicle.
This type of flaw is not uncommon. It is certainly not justification for replacing the vehicle. Many, many vehicles have one or more components updated by the manufacturer during the first few years after their introduction. Those people who experience the flaw during the warranty period have the upgrade applied at no cost. Those people whose part does not malfunction until after the warranty period usually have to pay for the upgrade.
The bottom line here is that Toyota is charging an outrageously inflated price for the part; and for their labor to install it. This kind of theft is a cash cow for dealerships; which is supported by sheepish owners who feel obligated to have the dealership perform all service procedures. It is becoming more and more common in the industry. But neither you, nor any other owner who learns the facts behind the situation, needs to submit to such thievery. If your car does not have a California specification emissions system; Rock Auto sells a brand new bank 1 exhaust manifold and integrated catalytic converter, under Dorman part #674847, for $387.79 plus shipping. This is the new design part.
If your car does have California emissions; you'd have to buy a used part, as described above.

Zaken, Thank you very much. You are the only one i can coun't on to get the truth from. I will have my mechanic check for leaks.
You have given me some hope, chuck

Gee, and I've never even communicated directly with Kirstie. Thank you both for the kind words. They came at a very opportune time; because I had just lost my cool with a new poster in the answers section; who appeared like he was determined to break every rule in the book, at a time when Stever was away on a road trip. It had really pushed my buttons, and I was feeling like quitting the whole show.
When Karen straightened me out about what I didn't realize about this guy; I felt sheepish. So it was just the time for some warm fuzzies. NOBODY'S PERFECT HERE

Nope, nobody is. I've been saved several times by the ability to delete my own posts... or the unusual moment of self control when I just walk away for awhile. We just appreciate the effort, even if sometimes it is imperfect!

Hi Zaken, according to the TSB 0114-08 under required equipment there is a note that statesm: Software version3.01.000 or later is required. supplier ADE part # TSPKG1.
DO you know what this is? Is it a reflash of the ECU? If so does it need to be done by a dealership?
I was also wondering about your opiniomn on airtex/wells sensors? I noticed they are a lot more money. Wondering why?
I am thankful for all your help, chuck
