Code E161 - Lower Valve Error
Reason; Power amplifier could not detect presence of lower valve coil.
Possible Cause/
Corrective Action
Lower valve missing.
Open or short circuit in lower valve or wiring; master control relay missing
or stuck open; main contactor open circuit (especially after it has closed);
communication error due to PMT. Allow PMT to reboot before turning truck
ON. Bad power amplifier.
Hey Bud, I know its an old thread, I am having the same issue, was you problem ever solved.
Please let me know.
Main harness replaced. Still E 161 code. Any ideas?
Pull the three bolts and remove tiller arm. Most likely have a broken wire. With code 161 most likely a can wire broke.
I replace the contactor still code out
