O2 sensor circuit- Bank1, Sensor 2. I have a Toyota RAV4 2004 and my VSC TRAC and check engine light keeps on turning on. Happened for the first time a few months ago, and all I did was open the gas cap and then tighten it to click once. The lights went away. But forward it to a couple months later, it’s been 2 occurrences in the last week.
The O2 sensor closest to the engine is know as the "bank #1, sensor #1" or B1S1. The sensor furthest from the engine (the one in your video) is known as "bank #1, sensor #2" ( or B1S2), which is why the YouTube video was titled the way it was. The second pipe you see in the YouTube video (the one nearest the passenger side, or RIGHT SIDE OF THE ...
2011 Tacoma DCSB. 3 inch Icon lift with UCA’s. Bank 1, sensor 2 is the rear sensor, behind the catalytic. Bank 1 sensor 1, is the front one near the engine, depending on the model year, an Air/Fuel sensor (2000 and after) or a regular o2 sensor (before 2000) Only get DENSO sensor. Toyotas are known to be picky with other brands.

Most likely the scan tool you are using is just defaulting the zero value it receives as 99%. Fuel trims are ONLY measured using the primary O2/AF sensor in the manifold. The P0420 could be related to a dead sensor ...
So bank 1 is driverside and sensor 2 is the downstream, after the cat convertor. Make sure to use Denso sensor. Amazon or rockauto are usually cheapest. cruiserguy, Apr 5, 2019. #2. freebird4446 [QUOTED] [OP] likes this. Apr 5, 2019 at 7:52 PM. # 3.
Bank 1 means the bank containing #1 cylinder. From everything I can see, on any transverse mounted V-6 TOYOTA engine, the bank closer to the firewall contains cyl #1. Sensor 2 will be the second sensor in that bank, with the count starting at the engine head. It should also be the last (closest to tailpipe) sensor in that bank.
2000 indestructaco! Hello, welcome to tacoma world. As said above, bank 1 sensor 2 is the rear sensor, behind the catalytic. bank 1 sensor 1, the front one near the engine is, depending on the model year, an Air/Fuel sensor (2000 and after) or a regular o2 sensor (before 2000) Only get DENSO sensor. Toyotas are known to be picky with other brands.
The code is for Bank 1 Sensor 2. It is the sensor located on the exhaust pipe under the car (near the oil pan) and not the exhaust manifold catalytic converter mounted Bank 1 Sensor 1 or California only Bank 1 Sensor 3 which is located after the underfloor (second) catalytic converter. I would only run a Denso or NTK (NGK) O2 sensor on a Toyota.
