Engine sensors-reference resistance etc?

Hi folks. I'm looking for reference resistance values for; CPS, IAT, MAF and any other sensors they I've forgotten. I've got a CD manual but I've not come across them yet. Ta.

CPS - digital
IAT - from 600 ohms (-30 deg.C) to 2 ohms (100 deg.C)
MAF - digital
ECT - 3 Kohms (20 deg.C) to 580 ohms (90 deg.C)

As per other sensors, when you'll remember what you need, I'll tell you more... Laughing Laughing

Thanks very much Alex. So the CPS doesn't have a range then. I was looking to try and get some readings the next time I suffer from hot starting issues. I tried experimenting today but the ambient temp is 17C on a windy day so it's just bleeding heart away from the engine bay!
Went from 46C under bonnet, which it started fine from, to 24C in the space of ten minutes so not the soak environment I was hoping for LOL.
