[QUOTE=Cal Learner;... it's the hefty 4-prong CPS at the back of the cylinder head. ..

That is the temp Thermistor sensor .. NOT CPS.

CPS is a Hall Effect sensor at the flywheel and has nothing to do with 4- prong temp sensor or Thermistor resistance chart.
CPS is ECU/Ign trigger signal.

Go to parts look-up on top of page.

Crank Position Sensor.
