I hope I haven't already asked this question have 2012 Bluebird . Driver came in with an SCR warning . Came up with a 3232 . I thought relay .we have had issues . Started bus up went to move it and code came back . Went to bring it into the shop and warning stopped . So I wiggle wires and anything connected with the scr system . Any other ideas
Looks like you have a bad Intake NOx sensor. We replace a fair amount of these; Intake and Outlet Nox Sensors. Easy to do, but not cheap. Sensor comes as one piece with the module.
No, there are different part numbers depending on application. If you remove the current sensor, you should be able to read the part number on the bottom of the module. Call your dealer and confirm part number with them.
3 part numbers for both in and out i think , and the only difference is the length of the harness but all will work , most buses have the shortest harness, and the trouble shooting for nox sensors is easy 12 volts ,ground and 60 ohms on data link and they ask how many inactive counts , think for the 4 codes for nox sensors they are all 2 or 3 steps
OEM trained in wiring and all engine platforms for over 20 years
Cummins 3232 code any ideas
