First post but I’ve been following the forum for a long while. I’ve tried searching and not having any luck here with a solution. I’ve got an 06 nytro er that I picked up with a bad stator. Noticed when I test rode it the tach wasn’t working and had er-1 on the display. Thought it may have been due to the stator. Anyway, changed it and now the sled runs and charges perfectly but still have no tach and the error. Checked all grounds (all clean and good continuity), swapped the ecu, traced wires and everything looks good. The 3 relays in the right footwell area are starting to green up a bit (that’s on my hit list this week) but everything seems to check out. When I start it up, the tach does its test sweep so that tells me the dash is working. Other than that and the code, sled runs like a top. Any suggestions on what to look at next? Everything I’ve found is for 08 and newer so far.
Thanks
