Most of the sensors make sense, but some don't. Is there a place that lists in plain English what the abbreviations for the sensors mean? For example the attached picture shows a graph for "1/1 O2S(V)". (car is 2004 PT Cruiser GT) My assumption is that this is the upstream oxygen sensor and the units are volts. However, from what I'm seeing online, the O2 sensor should oscillate between 0-1 volts. This graph shows 2.54v-3.39v. So, I'm wondering if I'm misunderstanding what the graph is telling me. There are a couple other lines of data that pertain to the O2 sensor, but none of them read between 0-1 volts. Edit: Just found this: https://www.snapon.com/Files/Diagno...municationSoftwareManual_EAZ0025B01H.pdf I'll have to start digging through it. Last edited by Dartslantsix; 04/14/22 11:12 PM.
