I know I can look at the actual output of any attached pin for the EMU using a laptop, I'm curious what to look for.You use a scanner with scope feature to monitor o2 sensor reading to n from ECU, EMU has port to plug in a scanner or laptop for monitoring PIDs sensor/actuators readings
You can't. Until it is completely warmed up, an O2 sensor is just a chunk of ceramic, and it will produce no signal whatsoever. Once it is warmed up, it will put out a voltage if you give it a rich mixture. The way that you tell that it is working is by watching the voltage go up and down in closed loop as the mixture oscillates between rich and lean....How can I tell from the EMU scope output of an idle O2 sensor that it is working?
