According to research I've done on the web, the W in WO2S11 stands for wideband, meaning it can calculate much better than a standard O2 sensor. This, I would assume, is what your car is utilizing to get its O2 reading and not the O2S11. And yes, that would be for the bank 1 sensor 1 (upstream or before cat). Your issue is not with the B1S1, though, it's ...


No, you don't have to rely on wire colors to figure out what's what. With nothing more than a decent multimeter and premix flame (blowtorch or gas stove), a two-test sequence can reveal the identity of each wire, assuming the O2 sensor is fully-functional: Determine the heater wires This should be done first. These wires serve to heat up the O2 sensor ...


Yes it will be fine...if you correctly solder it. If you dont know how to solder then i would suggest a crimp.


Solder (60/40) or any other lead-based sort has little mechanical strength. And it decreases as heat goes up. Furthermore, some of the wires used in various places don't work very well with field soldering (such as Litz wire). On the other hand many of them don't work well with mechanical fastening, ie, crimping. Depending on the wires you're working with, ...


It should hold up. It melts at around twice the temperature where water boils, which I don't think you'll ever experience in the engine bay (unless it's touching the exhaust). But the greasiness in the engine may make for a poor adhesion. BTW: I am one of those people who would rather crimp than solder.


Typically, these emissions/inspections tests connect to the on-board computer, and that computer will tell you if a code has been cleared. For example, with the O2 code, I think most cars require you to drive 50 miles before the computer will give the "all clear" after the code has been cleared. If you had 3 O2 sensors replaced, then my guess is that your ...


A narrowband sensor can only measure 14.7:1 AFR (stoichiometric) , where as wideband sensors allows you to measure a range of AFR ~(<10 to ~20). ECU's that rely on narrowband output maintain the AFR at stoich by using closed loop control (cruise etc) and may use various interpolation methods for increasing the open loop accuracy for AFR other than stoich. ...
