I have a 2004 2.3 and am ytring to be put under the impression that all the "new" 2.3s are duratech? I cant find any technical info for my truck. pretty sure it has a steel block tho and is not a dura

 

Yes it is.

i need to find the crankshaft sensor and wana be certain where it is before i start takin my truck apart. any clue where that might be? behind harmonic balancer and timing chain cover?

 

Right above the Crankshaft pulley.

When you pull the sensor, you need to make sure the engine is at TDC (top dead center).
The new sensor you buy should come with an alignment tool, you need to put the new sensor in the same place as the old one.

Then, reverse procedure.

 

any way to test this before replacement? truck was under water and now has misfire on cyl 4. could this be the cause? scanner gave sensor condition as code

 

Unplug the connecter, clean and check the pins.
Disconnect battery, and let sit for 30 minutes.
Re connect both.
The battery should have reset the computer. then drive it and see what happens.

 

gona do it now. ill let you know if it worked

 

ok, i took neg batt term off and unpluged crank sensor then let it sit for a little over an hour. in the mean time i pulled every fuse and cleaned it with electrical spray. hooked batt up and sensor and the code was gone. i have drivin about 35mi and still no code. now did this just clear the concern or is it possible that the sensor lost its pick up sense under water and now that it was cycled and dry it can pick up the reading again? it still has a misfire only when i initually give it gas? mabey coil? plugs are new?

 

If you code hasn't come back, then i wouldn't worry about the sensor.
If you still have a misfire, Start with Spark Plugs and Plug Wires.

 

idk? ill try the wires but all this started when it took a dip. dont see how that could of affected the wires? i drive this truck for work and just dont want to be in bfe and have it die.

 

If you have a confirmed misfire, i'd start with the easier thing to check. Such as spark plugs and wires. Inspect the wires for any cuts or tears because it may have got wet and shorted.

 

i took a better look at the wires and found that the inside of the boots were corroded. i cleaned them and put them back on and no more misfire. also cleaned maf sensor and got a code. figured it was an emissions code so i took the neg off and got somethin to eat. started truck and no more code but got it scanned anyway. i got a P0606 ECM internal communication error. dectected internal memory fault, but still no idiot light? truck runs alot better tho

 

Good job!

 

why is that good? there is still a problem somewhere but its not registering on the dash?

 

Good job on getting most of the problems fixed.

Check the ECM fuse, if the fuse is fine then try clearing the code. If the code comes back you may have to reprogram or replace the ECM.

 

"also cleaned maf sensor and got a code. figured it was an emissions code so i took the neg off and got somethin to eat. started truck and no more code but got it scanned anyway" I guess i should clarify, i got a check engine light and cleared it, then ran good with no check engine light. got it scanned, even tho no light, and got a P0606

 

Have you checked the ECM fuse like I said though?

 

no, but if the fuse was bad how would it be getting power to controle everything els that is controlled by its signal. wouldnt i atleast get a check engine light? im gona check it now tho. ill let you know in a min

 

checked ALL fuses and cleaned terminals with electrical spray. disconnected computer in firewall, cleaned connector, and visualy checked wires for breaks or problems in harness going to computer. everything is good. i re-wrapped harness and hooked everything up and ran truck. no check engine light but i noticed a slight misfire on low rpms. about 900-1200. still running pretty good tho?

 

Don't worry about the P0606 code that's just the computer saying it lost power.

 

thank you
