Hi to you, this may concern I'm having an overheating problem on my car listed above. I've been trying to locate the coolant sensor or a few days now, this is the code that popped up when i put the ob2 reader on (p1299).

Hi,

The code is related to what is called a cylinder head temperature sensor (CHTS). This is located at the center of the valve cover top, between cylinder 2 and 3 ignition coils.

I attached the directions below for replacing one. However, when the engine is cold, make sure the coolant level is full.

Let me know if that takes care of the problem.

Take care,

Joe
