Hi all,
Ok, son's FEH tripped a code last week. Read it as P0128 which indicates coolant temperature out of range. After some investigation, I purchased a new cylinder head temperature sensor and replaced it. Wiring was good, no corrosion etc. Next day it showed the CEL again and tripped P0128. Most history of this is a sticking thermostat, so I ordered a Ford thermostat and housing. OMG what a PITA to change that. Anyhow, it is all done and hopefully that cures it but I also ordered a temp sender unit listed for the idiot light. I cannot find where this sender is located. Anyone know????
Thanks
