Hi, like the title says the eld is showing 59.77 which sounds abit dangerous, and during all my datalogs the A.F never moves from 14.70, i had an error code last week for a secondary o2 heater malfunction so i replaced the sensor and that disapeared but when i checked the errors their was one for the eld, so i took it for a drive while datalogging it and noticed that the AF doesnt change and neither does the ELD they are both stuck at 59.77 and 14.70, is this ecu or more sensors died a death

P.s sorry for the up n down data log the roads round where i live are short and built up with traffic

Do you have an external wideband input to the ELD? If so, then it is stuck at 4.5V. If not, there is a wiring problem between your ECU and the ELD, or it is the ECU itself. Since you had a SO2 error recently, and it shares some of the wiring with the ELD, it could be related to the SO2 error you got. Check the wiring and grounds for both the SO2 and ELD.
