Hi all, I have a Cummins freight 2011. I am having multiple issue.
First, it started off with a Doser pump issue. We changed it, and then found out it was a harness going to harness that was corroded. Once we placed the harness, we got new codes. Once, this was fixed, new codes came on. It asked for a Doser pump override test, which cleared some of the codes BUT this time I have AFTERTREAMENT 1 intake NOx sensor (code 3232), came on. Before changing the sensor we checked the plug. I had 12 volts and 60 ohms. So, that was good but when I changed the sensor it became inactive and came back active. It goes on and off. I spoke with couple of guys. Some are telling me it’s wirring issue but others are saying it might be the outlet sensor. Before I keep spending, can someone help me out on this one? Thanks in advance!
