Question

What is the most likely cause for an engine code P1299 in a 2003 Ford Focus?

Answer 1

Hi there,

This code is for the cylinder head temp sensor. It indicates there is an issue with the sensor itself. The location of the sensor depends on which engine you have in the car.

Also check to make sure the engine isn't running hot. If it is then check the coolant level and the thermostat.
