Where is the cooling fan sensor switch located?

Hi,

The part number you provided isn't for this vehicle. I attached a pic below of the cooling fan wiring schematic.

On this vehicle, the cylinder head temperature sensor is what is used to determine cooling fan operation via the PCM.

Let me know if this helps or makes things more confusing. LOL

Take care,

Joe

See pics below. Note: I had to cut the schematic in half to make it readable. I did overlap the two so you can follow from one to the next.

Hi,

I don't believe this one is under the intake. It should be on the passenger side cylinder head (above the exhaust manifold).

If you look below, I attached some information to help you locate it and replace it.

Let me know if this helps.

Take care,

Hi,

I just looked at the pics I sent. It is showing two different locations and I didn't realize that. I reattached a pic below and circled the thermostat housing and have an arrow pointing to the sensor. Based on that, it would be under the intake.

I went to two different manuals and they both seem to contradict each other. Check in the area where I have the arrow pointing to see if you find it. Also, I highlighted the area where I believe it should be in pic 2. They just don't provide a clear picture in either manual.

Let me know.

Hi,

What you described is usually the result of a faulty sensor. The sensor in the pic above is the CHT sensor. See pic below.

That is the only one I can find. Also, that is the sensor used to turn on the radiator cooling fans. I attached the wiring schematic for the cooling fan circuit. The sensor used is the CHT. See pics below.

I had to cut the schematic in half to make it readable, but I did overlap it so you can follow from one to the next.

Have you tried scanning the can-bus to see if there are codes stored in the module?

Let me know.
