2006 Toyota Sienna check engine come up, went to parts store to scan, showing bank 1 sensor 1, changed bank 1 sensor 1 after check engine come up with a code P0058, at a parts store they told me to changed bank 2 sensor 2 that what I did but check engine light still on
Your first mistake is having a "diagnosis" by a parts counter sales person. I wrote an article about his very subject. You might find it helpful. Click the link below to read the article:
What Else Could Be Wrong?
Then, you did not list the code that you got the first time, so there is no way of knowing if the parts sales person told you correctly on the first time or not.
Diagnostic Test Code (DTC) P0058 is defined by SAE J2012 as "HO2S Heater Control Circuit High Bank 2 Sensor 2" (SAE J2012 is the standard by which all vehicle manufacturers must define the "generic" or "non-vehicle specific" diagnostic test routines necessary to properly diagnose and repair their cars.)
To understand what is going on here, it is very important to understand that this code definition DOES NOT tell you to replace the oxygen sensor. This is an oxygen sensor heater CIRCUIT code. The heater circuit on your vehicle includes the battery voltage (B+) supply circuit and the heater control (HT) circuit to the Powertrain Control Module (PCM). Failure of either of these circuits will cause DTC P0058 to set.
The B+ circuit consists of the BLACK/RED wire at the oxygen sensor connector which gets its power from the EFI 2 fuse (10 Amp) located in the engine room junction block. There are several things powered by this fuse and there are several splices and branches in the wire. Voltage MUST be checked at the O2 sensor connector.
The control circuit for the Bank 2 Sensor 2 heater is the WHITE/BLUE wire that runs only from the O2 sensor connector to connector E7 PIN #33 at the PCM. BOTH of these circuits must be check to make sure they are not shorted to ground and that they have continuity to their connections at both ends.
Also, after repairs are made, all engine control codes must be PROPERLY cleared using an appropriate scan tool in order to make the check engine light turn off and to prevent additional problems with the engine control system. Many uneducated do-it-yourselfers will tell you to disconnect the battery cables to accomplish this. That is NOT the correct way to do it, and this can cause voltage spikes that can damage sensitive computer equipment in your car and possibly cause fault codes to set in several of the computer modules in your vehicle.
Many do not believe that this is possible. If you want proof, pull the plug on your home PC and plug it back in a few times and see if it doesn't wreck your hard drive....

You don't need a part number, you just buy by 'year make model'. Don't go cheap on sensors, make sure they are Denso OEM quality and not made in China or Mexico.
Hi there, I believe the sienna engine is situated at 90 degrees to the vehicle length. Bank 1 is on the side of the engine closest to the passenger cab (Bank 2 is on the forward side). sensor 1 is before the catalytic converter (sensor 2 is after). Follow the exhaust manifold then exhaust piping on the cab side of the engine until you find the sensor with a wire screwed directly into the pipe. That's it. You will require a special socket head for it- they're cheap. Good luck.
sensor a will be the one closest to the exhaust manifold on the engine block bank 2 is, well if you look closely at the engine on a v6 , bank one, the first cylinder is just slightly ahead of the first cylinder on the opposite side .
The air/fuel ratio sensor has gone bad (basically the O2 sensor). The code P1130 is Bank 1 Sensor 1.
Sensor 1 is before the catalytic converter coming off the exhaust manifold. Bank 1 is which ever side cylinder 1 is on your engine. In this case its a sideways engine and its closest to the firewall.
Solved. I have 2008 Sienna with Check Engine and VSC lights on. Scanned codes were P0051 and P2197. Oxygen Sensor Bank 2 Sensor 1 needs to be replaced. You can see this sensor on the right side of the engine when you open up the hood. You need to get an Oxygen Sensor socket (I used Tekton 7/8in 22mm which costs $9) and a wrench extension to reach it. Spraying liquid wrench a few times on the base of the old sensor also helped to loose it. The replacement sensor I used was Denso 234-9049 which costs $85 from eBay. Lights went off after the sensor was replaced. It took me 30 minutes to replace.
Very common for the 3 L motor to have a problem with an oxygen sensor. The best way is to read the OBDII code from the computer and determine which of the Three sensors is bad. Usually it is either Bank one, sensor one or Bank two, sensor one. The hard one is B2 S1 down & behind the engine & firewall. Great patience and determination will get you through.
