tacoma dies in about 3 ft of water

Understood, I guess I'm missing something because based on the majority of responses in the first 3 pages of this thread, you'd think it was a really dumb question...

So you can deep 6 the alternator and it's not the water that would kill it, it's everything else floating around in the mud that does the truck in.

 

I think it's a defective high water sensor module. Put the garden hose to it sitting in the drive way the fan in that much water is going to throw water every where so spray every thing until it quits.

 

I'm leaning in that direction also.

First off, sry OP for all the BS that happened in this thread... select few of us dont take shit seriously. i understand why your mad....

But for real..... is it more than this much water?





if u were to estimate how high is the water coming up? like past the oil pan? past the crank pulley?

Im also a tech..... thinking its electrical related as well. i dont have to insult ur intelligence by telling u a short will cause the ecm to shut down. especially if it was maybe a cps? what other electrical is low that the ecm requires to run...

 

@ 28 inches is when it starts to cut out and @ 30 to maybe 32 inches is when it dies

 

I think its about over the crank pulley

 

is there a c/e light? i would think there would be a code?

 

The only code stored is o2 sensor bank 1 sensor 2 and for iat sensor

 

what codes? short/open for the o2 sensor? what is the code for iat?

 

Intake air temp sensor code.

OP: If you are getting to the crank, what about an exposed crank sensor wire? According to what you said it happens when the watter is near crank level. Just an idea.

 

i know what an iat is???????? which code? that could possibly effect it. and yes thats what i was gettin at the cps

 

The o2 code is because I have it straight piped and it don't have the second o2 and the iat code is a circuit malfunction

 

Only 1 IAT code for that year/engine

Intake Air Temp. Circuit

Open or short in intake air temp. sensor circuit
Intake air temp. sensor (built into mass air flow meter)​

ECM


EDIT: OP you are too fast.

 

so correct me if im wrong.... if the iat is shorted or open, it sends the signal to the ecm that will tell the ecm its either something srupid like -57* or its 230* something like that. so say he runs through the water and water causes a short, ecm sees -57 and umps fuel thinking its cold as hell out.... could kill it right?

 

I can't remember the code p # but I will hook my scan tool up to it tomorrow and ill let you know the number and exact definition

 

This thread turned around quickly - I'm interested to see what the problem is.

 

agreed. thanks for the last page or so of interesting debug ideas.
