We tested the sensor on the top.of the radiator, not sure if that's the correct one
Mechanic: Leon Poston,

What cat engine does it have? There should be at least one, most cat engines have 2 coolant temp sensors on the top front of the engine that screw into the water jacket of the head.

I will check tomorrow to be sure but it should be near the front. It could also be 8th the thermostat housing. I will let you know tomorrow.

Thanks,do you test these sensors as you would a automotive sensor. Is there a way to bypass it to make sure it will run if replaced?
Mechanic: Leon Poston,
 replied 2 years ago
It depends, if the sensor is normally open you would want to unplug it and try it. If the sensor is normally closed you would want to jump the wires together and try. You can try it both ways. The worst that will happen is the machine will shut down.

I tried jumping the sensors unplugging the sensors and only miss answers I don't know that that's the problem but it still runs for a few minutes first time it will quit the next time it'll only run for like 45 seconds and then quit it doesn't even reach operating temperature thought enough I need to take it have it scanned for codes or there's another way to get codes out of it it's an 05 model sorry it took so long to get back I've been tied up with some other stuff
Mechanic: Leon Poston,
 replied 2 years ago
I am not sure if there is a way to get flash codes... If you would like I will opt out and another expert may know how.
