Can low coolant temp prevent ECM from PE mode?
If the coolant temp is 131*F, will this prevent the ECM from going into PE mode?

Re: Can low coolant temp prevent ECM from PE mode?
The answer is that I still can not get the ECM into PE mode even with a coolant temp of 180*F. So I still have not figured out why the ECM will not go into PE mode even though the TPS is full open, TPS = 4.4V..
I really could use someones help here!!!!

Are your constants for PE set correctly (for your setup)? I'm still learning; so, other than that, I have no other ideas.
