TomK Posted Sunday at 14:18 Share Posted Sunday at 14:18 (edited) Hi all, Got an '08 350z here and I'm getting the P2A00 Code which is for the Oxygen Sensor 1 on Bank 1. I bought a cheap OBDII scanner to confirm the fault and to try to find the cause by using data from the sensors. However, I am not 100% sure on what I should look for. I've researched online but my issue isn't clear. I'm aware it is not necessarily the sensor itself, but the values it is outputting are off from what they should be, hence the fault code. I know potentially an exhaust leak can be the cause? Anyways, I'd like to attempt to diagnose it myself before trying to fix or replace anything. I've attached some graphs to show the data I'm getting. I'm hoping someone here might have some more experience and knowledge to help?! If more data is required let me know what I should be trying to look at. I've read about normal voltage readings are below 1, however I notice Sensor 1 on Bank 2 is going above 1, but that isn't the sensor with the fault code. Any suggestions or help, no matter how small, would be greatly appreciated! Edited Sunday at 14:19 by TomK Quote Link to comment Share on other sites More sharing options...
