Which O2 sensor is Bank1 sensor 1

[Ebenezr]

My engine is throwing a P1133 error code which is the bank1 sensor 1. Does anyone know what sensor this is.?? Passenger side?? driver side?? before or after the Cat converter? Thanks.

Crud....I know this....

it matches up with the same side as the cylinder....1,3,5 and 2,4,6.....

...I think...

so Bank 1 would be on the same side as cylinder #1.

Now the question would be, what side is cylinder #1?

[Ebenezr]

Cylinder 1 is the passenger side. Hmmm.

Cylinder 1 is the passenger side. Hmmm.

Passenger side. Sensor closest to the engine, I believe.

Dang it Mark...You always know this stuff. I almost PM you on this before I even started this thread!!!!

[Ebenezr]

Well I don't know. I replaced bank 1 sensor 1 according to this diagram the passenger side. I let a mechanic pull codes the codes again cause it didn't fix it. He said it is throwing the bank 1 sensor 1 code still and that I replaced the wrong one. He says bank1 sensor 1 is always the drivers side.....So were did you get this diagram?????

[deermagnet]

So were did you get this diagram?????

That's from the '99 VX repair manual. The sensor is not always the problem. The sensor is sensing a problem somewhere else. I'm on all my original O2 sensors after 252,000 miles, so they are not prone to failure.

I'll look up info on that code later tonight or maybe someone else can post it sooner.

I KNEW IT!

Look at me.... I'm Learning!!!!

I knew hanging out with the mechanic and asking lots of questions would somehow pay off.

[Ebenezr]

Oh and thanks.

Hillarious...

I posted something that I meant to put in the "showroom new" thread here, but then realized it and deleted it out. However, you can't delete the post, only the contents.

It was important for the trans man to put the O2 sensor back right but everybody was sure that Somebody would do it. Anybody could have done it, but Nobody did it. Somebody got angry about that because it was Everybody's job. Everybody thought that Anybody could do it, but Nobody realized that Everybody wouldn't do it. It ended up that Everybody blamed Somebody when Nobody did what Anybody could have done. So here I am trying to fix what Nobody did.

I just went cross eyed..... Good luck getting a "body" to fix it.
