p0300 and p0051 codes...

Hi all,

So I posted this on CT and wanted to know if anyone can help me out over here. I have a 2008 toyota tacoma, v6, automatic, access cab, trd sport, 4wd. I installed the doug thorley long tube headers about 2 months ago. After I put it in, I drove it around for a while and about a couple weeks later, I put the URD o2 sim. The CEL always kept coming on so I pulled it out and put the wires back. I put the empire o2 sim in about a week ago. That didnʻt help either, still had the CEL. So yesterday I installed a scangauge and it gave me a p0300 and a p0051 code. Anyone know or can help me out. I know what the codes mean but I donʻt know where to start.

Thank you in advance.

P0051 code relates to the 02 sensor in the exhaust manifold located on the passenger's side.

woohoo! i just fixed my p0051 cel code. it says its in bank 2 sensor 1 but it i replaced the sensor on the other side. bank 2 is on the passenger side but i replaced it on the driver side and like magic. just wanted to let you all know that if you guys ever get the p0051 code, it is not the passenger side, its the driver side.
Yes thats correct there was a bullitin put out where different engines have bank 2 sensor 1 on the driver side not the passenger side so you will never get the engine code cleared if you change the O2 sensor on the passenger side

 

Also everyone says Denso Denso Denso well I found out positively that some Toyota dealers are buying Walker O2 sensors and so did I so far so good

 

Bank 1 (B1) refers to the bank that includes cylinder No. 1.
Bank 2 (B2) refers to the bank opposite bank 1.
Sensor 1 (S1) refers to the sensor that is located before the catalytic converters.
Sensor 2 (S2) refers to the sensor that is located after the catalytic converters.

The passenger side cylinders are 1, 3, and 5 Making the passenger side Bank # 1.
The drivers side cylinders are 2, 4 and 6 Making the drivers side Bank # 2.

Bank # 2 is not on the passenger side at all and never was.

 

Great now its all in the open ,now more people can have less problems installing O2 sensors
