mark427ci Posted November 12, 2009 Report Share Posted November 12, 2009 the thing I am trying to understand is the oxygen sensor wiring from the how to section. I have a sensor with one wire.... if I send power to it like the diagram shows, how does the signal get to the computer? Any help? Thanks Quote Link to comment

Thanks Power flows from the battery through the ECU to the O2 sensor and to ground on the block. The ECU is then able to monitor how much power flowed through it and makes it's calculation on that.
