Coolant temp sensor table

Pomaikai · 9-26-05, 23:07

Does anyone know the resitance of this sensor at different temps? When looking at the five coolant temp sensors it is the one on the right. I checked at ambient(102F here in texas) and I am getting 1.5k which is similiar to GM sensor at that temperature. Megasquirt is setup for GM sensors so I am trying to get as close as possible so I can just play a little with Easytherm and not swap bias resistors on MS.

I put 2.2k resistors on my board, all the jap stuff seems to be best with that, however 2.49k is easily close enough. you should be able to find that data on the msefi or megasquirt.info sites, or by searching for.

the table telling us which sensors use which resistance is about 2/3 down the v3 assemble page.

summary : Bosch and Nippon Denso are used in :

Acura, Audi, BMW, Honda, Infiniti,
Jaguar, Kia, Lexus, Mazda, Mitsubishi,
Nissan, Suzuki, Toyota, Volkswagen, Volvo (96-up)

which suits 2.2k best.

right, heres the data : left is ohms , right is degrees C.

edit, formatting didnt work out, see image.

and the photo of the plot :
