    Downstream o2 sensor?

    Hi This is the first picture that I have tried to insert, Please let me know if I have not done it properly.

    This is the o2 sensors on a Citroen c3, The downstream does not look correct.

    Can someone please tell me what it means please
    Is that value invalid?, if so why.

          I use my PC and when making a post just scroll down and see something called manage attachements ,click on that to browse , click on pictures, scroll to the picture you want to post and double click on that , click upload then submit reply. I had to get a image resizer because the pictures would post too large on here and annoy folk.

            Same here. I take pics with my phone, send them ti my email, download them unto my pc then post them. Sounds like a lot of work, but it never fails.

              By E-mail is one way of doing it with pictures taken from phone , but I click share on my phone and select Bluetooth and select send file.(while I'm next to my older laptop with the USB Bluetooth dongle , I run a Blue Tooth mouse and play Blue Tooth speakers from. I click on the little up arrow in the tray on bottom next to the speaker symbol and select the blue tooth symbol, then select receive file. I usually send the pictures to saved pictures and resize them before posting to the forum. My newer laptop has built in blue tooth and doesn't need a blue tooth dongle .A Blue tooth dongle is nice to have and you can play music to a bluetooth speaker , and use the bluetooth mouse at same time.

                  If using Snap-on tools, you have the ability to capture a screenshot,
                  and then upload to this forum. If your Verus is connected to the internet,
                  you can do all that right from the tool itself.

                      In your pic it shows the Downstream O2 Status. I think what you wanted to post was the Downstream O2 Voltage.

                          looking at this now, I am not sure you be able to see it very well.

                            I say don't sweat the downstream O2 sensor until you find out why the car has the dead miss (assuming so if #3 fuel injector is allegedly not working. ) Stethoscope can compare injector sound.That car is probably running in open loop mode and downstream O2 might not even be getting monitored. That car kinda looks like a BMW Mini and that might only have 3 cylinders or 4 cylinders, so deal with why you might not being able to see the injector pulse on #3 first .
                            What's it doing and what codes you pull ?

                              I am going to put my verus scope on the injectors tomorrow and see what the real thing is doing.


                              Codes are

                              P0598 Controlled thermostat signal short to earth or open circuit
                              P1676 Controlled alternator control

                              I
                              cant see as they have anything to do with these injectors
