okay I managed to get hold of an fsm and I was trying to check out my crank position sensor but the only thing I could find was what they referred to as the engine speed sensor

THE ENGINE
RPM IS DETECTED BY THE ENGINE SPEED SENSOR INSTALLED IN THE CYLINDER BLOCK AND THE SIGNAL IS INPUT INTO
TERMINAL NE OF ECU AS A CONTROL SIGNAL.

when I test the ohms on this sensor it is nowhere near the acceptable range. I'm wondering if this is the same as the crankshaft position sensor. since I can't find that phrase in the manual. If so would a faulty one be enough to keep my car from starting

 

Your profile shows you owning an ES300 not an SC300/400. Consequently, this might be the wrong forum.

In any event, the NE signal is the typical Toyota/Lexus designation for the crank position signal. At minimum, you have associated the proper signal with the device that detects crank position.

I have a 1997 ES300 and a 1992 SC400. My question is in reference to the SC

 

here is a pic of the sensor I'm talking about

 

that is not the CKP. if i remember the sensor is on the lower side of the crank pulley

 

yup. easy enough

 

keep in mind in order to accurently read resistance of a component it must be disconnected from the circute

 

I just purchased my first Lexus... It is a 1992 sc400.
The engine light was on and I was able to pull code 13 & 21. The sensor in the picture shows some damage but I'm not sure which sensor that is... I need some help identifying it...

 

Ok, after a few hours of searching I figured it out.... for those interested in knowing, that is the hydraulic fan motor valve / solenoid....

 

Dónde queda el cigueñal de lexus is250

 

Estas en el sition equivocado. Si haces la busqueda usando la herramientas selecciona solo el sition de IS250, este es el sitio del SC400/300 motores completamente distintos.
