I have read for many hours online now trying to figure out where the A/F B1 S1 is at and still confused. I understand there is the difference in between the O2 sensor and the A/F sensor, however want to it is in absolutey sure I am instead of the best one. I have an 01 Taco V6 4x4 hand-operated 5 speed and have the P1135 message. Neighborhood Toyota shop showed it was the A/F B1 S1 and I notified the part. Now I am not certain where this sensor is located. I recognize it is upstream the the cat however I deserve to only find one sensor. Ns think there room 2 upstream and I am not sure if ns am looking at the best one. Anyone help??
There are two oxygen sensors on the 5VZ-FE Tacoma - one prior to the cat and one after. In this situation "O2" sensor and also the "A/F" sensor average the precise same thing. The sensor you"re looking in ~ on the upstream next of the cat is the one you desire to replace.

I recognize there is the difference between the O2 sensor and also the A/F sensor, but want to be absolutey certain I am instead of the ideal one. I have actually an 01 Taco V6 4x4 hands-on 5 speed and also have the P1135 message. Neighborhood Toyota shop verified it was the A/F B1 S1 and I notified the part. Now I am not sure where this sensor is located. I recognize it is upstream the the cat however I have the right to only discover one sensor.

Thanks.. Just to make sure when again, i think I have the right to identify the A/F now, and also the O2 sensor has a heat shield approximately it.. Is this exactly on the O2 sensor? Also, is there almost everywhere online to acquire diagrams?
Yeah those warmth shields deserve to be a pain to job-related around. Expect some bloody knuckles and also awkward occupational angles.

Man, you"re yes, really really really overthinking this. Just swap the sensor and go journey the truck!All the diagrams you might want/need are here:http://www.ncmoment-g.com/fsm/index.html
The A/F sensor is at the front of the vehivle appropriate by the header, the O2 is in the back, for this reason you want to replace the former one. Be ready for a battle to reach the plug. Ns did mine recently and it to be a bitch to obtain to the plug, b/c its means up between the height of the tranny and also the floor board, when i did acquire the plug undone, the wires native the new sensor were not long enough to reach the plug so i had to cut the wires that the old one and also use castle to length the new wires.If friend run into this problem dont be alarmed itd no unsual, good luck.

The A/F sensor is at the prior of the vehivle best by the header, the O2 is in the back, therefore you want to replace the former one. Be ready for a fight to reach the plug. Ns did mine recently and it to be a bitch to acquire to the plug, b/c its way up between the top of the tranny and also the floor board, when i did gain the plug undone, the wires from the brand-new sensor were no long enough to reach the plug so i had to cut the wires of the old one and use lock to length the brand-new wires.If girlfriend run right into this problem dont be alarmed itd not unsual, an excellent luck.

Only time I"ve checked out that difficulty is with Bosch parts. Harness was also short, complete PITA. OEM for the win.
Obscurotron.... Many thanks for the link... Simply what I have actually been looking for... And yes, I often over think the little projects due to the fact that they it seems to be ~ to be the persons the give me the many headacheshttp://www.ncmoment-g.com/fsm/index.html
Word. Simply a month or two before I removed my truck I had actually to replace this. It take it me much longer to journey to the dealer to choose up the component than it did to replace it. And also I had to spray the nuts down for a few minutes because I offered to beat in the mud! one of the easiest fixes I ever before had to execute on my old truck.
