Don't solder Oxygen sensor Wire????
I've read a mechanic book. It says on Oxygen Sensor page that do not solder Oxygen sensor wire because it might cause misleading the voltage. I'm kind of doubt if soldered wire would make different voltage reading from unsoldered wire. How can a soldered wire and unsoldered wire make different voltage reading? Does anyone ever heard of this or know this is true or false? |

Don't solder Oxygen sensor Wire????
Makes sense. Is there not a special kind of solder for situations like this?
There are many different types. TeGGeR® wrote: >>> I've read a mechanic book.

Just make sure that you have very good copper-to-copper contact, and
then solder. You won't have a dissimilar metal in the way at that point, but the solder will chemically and mechanically protect the joint. This is the essence of good soldering technique. The book is "right," in that some people (mechanics) just are not electronic techs, and don't really appreciate the correct way to solder a joint. |
