P012F What is the problem this code shows

Question

Have replaced radiator and hoses but not thermostat. Suspect it's related, but not sure.

Answer 1

HI there,

The code is for a correlation problem between the oil temp sensor and the engine coolant temp sensor. If the engine is still low on coolant then it could cause this and it would be related to the radiator replacement. This can also be an issue with the coolant temp sensor or the oil temp sensor as well.It is possible the thermostat if it's stuck open or closed could cause the conditions to set the code.

I have an 08 f350 157k miles on it.   I to have had the wench light come on after about 15 minutes of normal driving.   No gauge activity and no engine difference as far as operating.   I hook up my 14 tandem axle trailer with two commercial zero turn mowers and after the wrench light comes on the coolant temp gauge shoots up to hot and engine shuts down to 30mph.  Stop. Turn the key off and it resumes to normal then repeats.  I've changed oil temp sensor coolant temp sensor and tstats.  Is it still going to be the oil cooler? Mechanic told me she he was working on it it looked as if someone had  been into the oil cooler maybe even replaced it. If so what else could be the issue?
