Hi, I'm getting the code 09 which is the water thermosensor. I emailed mazdaformance and asked how much it was. They gave me the option between two different sensors, but they call them coolant temperature sensors. The numbers are F202-18-840A (fan switch) and NF02-18-840. Which one of these is the one that I am looking for?

Thanks,
Aaron

 

Not sure of the numbers.. But I know its NOT the fan thermosensor, so I'd guess it's the latter of the 2. It's the sensor that goes on the back of the thermostat housing. It's the 2 wire sensor. Sorry if that doesn't help.

 

NF02-18-840
