Question Hello ,David I have a suzuki sidekick 1.6 94, 4 doors, 4 Cyl.,16 valve. I want know how to measure the voltage generating in the oxygen sensor, I think i have heated oxygen sensor, and wire is color coded.Thanks, I appreciated for giving on answer. Thanks
Answer You need a voltmeter with a one or two volt scale. The colors I'm not sure of, but you will find that one wire is ground, one 12 volt(heater circuit), the other the signal. The signal will be a rapidly varying voltage, typically between 0.2 and 0.8 volts. Another consideration ... The signal will not begin to appear or fluctuate until the sensor reaches it's operating temperature(usually about 5-10 minutes.
