Hi,

 

This code indicates that the engine cylinder head temperature sensor indicates the truck is overheating and going into a fail safe strategy. IBelow is a list and description of the trouble code. You need to first check the coolant level, if it is low then look for a external leak somewhere. If the level is ok then it could just need a thermostat replacement. If the engine actually does not even seem to be overheating or hot then it could be the sensor giving it a false reading.

 

P1299 Cylinder Head Over Temperature Protection Active

Detailed Description
Indicates an engine overheat condition was detected by the cylinder head temperature (CHT) sensor. An FMEM Strategy called Fail-safe Cooling was activated to cool the engine.
Possible causes :-
  • Engine cooling system concerns.
  • Low engine coolant level.
  • Base engine concerns.
  •

    Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

    I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
