L300 shut down
Hi, i own a 2005 L300 that shuts down when the temp indicator is on the middle, theres no engine code, ive already replace the fuel pump.
took off crankshaft position sensor and multimeter reads 150k ohms, what other test can i do?

is it 100% consistent, meaning if you leave it idling in the driveway, it will idle up to that sane temp range, then cut out?
if the answer to the above is not yes, please provide some more details concerning when this happens (1st drive of the day(when engine starts out cold), after restart following stop for quick errand (when engine is warm)) while you're driving at highway speeds, stop n go, etc.
We need to nail down as much as we can in order to help you

Thanks for providing absolutely none of the information requested. Really don't understand why people behave this way, but here's the one and only response you'll receive from me
---------
So basically it becomes a dead short/piece of copper wire at higher temps.
I wonder how that affects the signal it generates.

ya know, both those readings seem whack to me way too high when cold and way too low when hot. I would expect 700-1200 Ohm range. certainly shouldn't short at high temp. sure your meter leads were not touching? Usually when they fail they go open circuit when hot which is what your situation sounds like, but then as they cool down they re-establish continuity
No CPS signal to PCM-->no spark + no fuel inj signal--> engine does not run.

Just like derf says: No CPS signal to PCM-->no spark + no fuel inj signal--> engine does not run.
funny thing is that i ignored all sensors because the check engine light didnt light up, but the cps just shutted down spark and fuel when it got warmed.
