Has anyone ever had OB2 code P01F0 for Coolant Temperature Dropped Below Diagnostic Monitoring Temperature? We recently had a cold snap here in Texas and my 2013 Duramax check engine light came on with this code. Trying to figure out what might have caused it.
So it’s just the way it’s going for me right now but got a po657 today did a little search but not seeing that . U guys got anything I should look for ?thanks. I cleared the code and it has not been back thanks again !
