Control Pressure (Warm-Up) Regulator question

[Larry C Leung]

Collective;

Trying to assess whether or not my Warm Up Regulator is electrically 
out of spec or not, or do I have to do the fuel system pressure checks:

Patient, '89 200Q, MC2

Bentley says that the temp sensor check value is "approximately 14 - 22
ohms"
Checking temperature range 68 to 86 degrees F (20 - 30 C), although I
don't 
really think that this applies directly to the resistance measurement
range, it's 
part of the output test section of testing the unit. 

At 75 degrees F (22.5 C), the unit resistance checks at 12.3 ohms. If I
go for a 
percentile basis, it's about 12 % below spec. Is the Bentley
"approximately"
tolerance to this degree, or is the unit electrically okay?

As always, TIA,
