COT sensors

[tdotcv]

There are two sensors one is the coolant temp sensor and the other the cylinder head temp sensor. Which side is driver's and passengers side. I have a check engine light because of one of these but I believe only one of them sets off the light. Is this true?

[RF Overlord]

It is true. The one for the gauge is connected only to the gauge, not to the PCM.

Unfortunately, I can never remember which one is which and the FSM is unclear.

Coolant temp gauge sender/sensor is on driver side.
Cylinder head temp gauge sender/sensor is on passenger side.

Passenger-Pointy end
Driver-Flat end

The Passenger side tells the pcm what temp it is.
Drivers side feeds the instrument cluster.

Forgot I had to change the sensor. Which one sets the engine light off is it the driver's side? Would any of these below work.
