Bentley Question - Temp Sensors

1
Evening All,

I am working on a Syncro project and struggling to interpret the attached Bentley info. Looking at 24.45, does this read that the air flow temp sensor and the coolant temp sensor are essentially the same and have identical temp to resistance profile?

Jon.

Jon, Its been a while since I have looked at this but in my morning haze I would say the diagram on the right half is for the coolant temp sensor and the left half is the ambient intake air temp. Greg E

Jon, Greg,

Yes, that’s how I read it.

Thanks chaps. I think this is one graph though as the temp "x' axis is continuous. Just wondering if it applies to both air temp and water temp sensors? From what I have read it appears to be the case but the Bentley layout is confusing.

Right you are Jon. The graph has been split so you can see the detail as the resistance changes very little between 50c and 100c. I checked a known good ect sensor and it is on 2150 ohms at 20ish c. I can check my air temp sensor in the morning if you like.

Jon check out page 24.19 (dijet but same) and 24.57. Greg

Thanks Greg. Sorry for the late reply. I just did the same test on my spare temp (water) sensor and got the same result. Would be good to confirm the air temp sensor but I can do this if you don't get chance. Presumably I can do this from the pins on the ECU plug rather than at the sensor direct?
