If you lay up the Software Dashboard to display Both O2 Sensors, you will want to see them behave SOMEWHAT the same.. Usually the Displayed Gauges will be cycling above and below the Majic .45 Volt range when at fast idle
This is normal, and is telling us that everything is hooked up and working .. O2 Sensor wise..At Warm hard Idle, the O2's will not be used for any fueling choices, and the ECU will not be using the output of them for any changes.. HOWEVER, us humans can use the information to see if something is amiss.. While in Idle, the ECU should park the Fuel Mixture LEAN.. That is a Voltage below .45 volt. So at IDLE, BOTH the gauges will display a voltage less than .45 volt If you get an idle voltage above .45 volts then LIKELY you have a Leaking Injector or O-Ring.. What is a 53 any way .. I did not look.. Cj
