I have installed an Air/Fuel ratio meter on my bike, with a Bosch O2 sensor # 11027 installed in the exhaust.
I need to test the O2 sensor, because the meter is showing me total different readings as per the dyno test I had performed today. I'm not sure if I have a faulty O2 sensor or Meter. On the Dyno at 2500 rpm in 5th gear under load the Air/Fuel ratio is 13.5. On my meter at the same rpm it shows way lean say 17.1, so I know I have a problem with either the Meter or O2 sensor.
Is there a way I can test the O2 sensor?
