Can anyone tell me the resistance on the coolant temperature sensor? I keep getting p173B. 2008 r56 n14. I’ve replaced it twice now. One had 7.50 ohms and the other 6.33ohms. I’m sorry, I don’t have a Bentley manual.

 

Google the part number and find equivalent parts. You may stumble across a data sheet or two.
6.3 and 7.5 Ohms is pretty close. Guess that's at room temperature. only compare two devices
at exact same temp. Obviously resistance hugely varies with temp, not just by one Ohm or two.

 

good idea
