Temp II sensor readings
Brand new sensor and I’m getting the following readings.
In car at 20c 740 ohms on both pins
Out of car at 20c 720 ohms
In 80c water 250 ohms
In 5c water 900 ohms
In freezer for 30 minutes 1k ohms
WSM has 0c as 4-6k ohms.
So from what I’m seeing the hot readings are ok but cold readings are way off. Car does start when cold but not as quick and is a bit rough.
Is it possible for a new sensor to be bad out of the box? I have a new one on the way and will bench test both. Just wondering if anyone else has had similar readings.

Not sure I can be of much help except to offer another set of data points for you. Original Temp II readings (tested in engine S2 Euro, running well):
10C= 6.4k Ohms
43C= 1.3k Ohms
54C= 1.1k Ohms
77C= 640 Ohms
82C= 620 Ohms
85C= 550 Ohms
Good luck with your troubleshooting.

As well we are planning to replace the LH, the coils and ignition amps as a preventative measure (everything else is new).
