oxygen sensor air-fuel ratio analog multimeter
Any difference between an "Oxygen Sensor" and this "AFR sensor"? Does it output an analog voltage that can be read with a multimeter?
I ran a multimeter on my carbed 89 Tercel's O2 sensor (only one, in down pipe just below exhaust manifold) and it read so close to spec (.75 volt?) that I wasn't sure of the whole control circuit's function...was something driving that reading to .75 besides oxygen in the exhaust gas? |
