Hi Michael, My name is***** will be glad to help. Bare with me while I pull up these codes.
Estimated Fan Speed Valid High
Estimated Fan Speed Valid Low
Estimated Fan Speed Voltage High
Estimated Fan Speed Voltage Low
These are all the potential FMI for that fault.... So either low voltage or a faulty fan however if you just had belt issues it could be related to the fan speed then.....
Is it running fine and not overheating? this could be from the pulley failure of why it delayed and threw this code
Thanks for the update Michael. Pleasure to help. Glad to hear you got this resolved.
