more information,
cleared the codes this morning.
it did not through any codes while cold.

after It ran for about 20 min at idle, still had no codes.
blipped the gas peddle and the short list of codes came up.

 

giving up and sending it into the shop.

 

turbo play sounds normal, rule of thumb is if you rotate the shaft and push sideways at the same time and the fins touch the housing it is shot, when the engine is running oil pressure centers the shaft and it runs on a film of oil

or any in/out play is a suspect turbo

Sorry, but WHAT does that mean??
is it a test?
something I could still try?

or do you mean the ecm is shot?

thanks, I just don't know much about these computer controlled trucks.

 

I would say yes if the power and grounds to the ECM check out OK. Pull the connector at the ECM and check for water or corrosion if OK load test power and ground using headlight bulb to load the circuit if light is bright then ECM.

 

ok, update.

shop says it is the ecm.
and that the batteries tested bad under a load.
the bad batteries took out the ecm.

so the ecm is 1295.00... OMG!!!!
new batteries will be around 200 for the two of them.

so why are these ecms... so truck specific that they need the vin number to order it...

 

I did not read the whole thread, but bad batterys will cause issues, change them first...
find a used ecm with same options as your truck, you might or might not need re-flash

 

I was wondering what the outcome was of your problem. I have a similar issue with my truck. Throwing codes 0237 and 0112. The dealer wants me to put a turbo in it but the turbo appears good and they admitted they never performed a boost test.

 

I had this very same issue and after tracing every wire on the edge I found that one of them had just come loose from the power source on the battery throwing just about the same codes and put the truck in limp mode. Took me all day to discover the broken wire but once I retired it and hooked it up check engine light and all codes went away and new truck again. Sounds like he got screwed on the ECM PCM deal

 

Ok, the truck is still down. The consistent codes I have are map sensor voltage too low and ait sensor low. I have found that I have 5 volts to both sensors and I have good ground at both sensors. So what are the odds of both going bad at the the same time? Is it ECM time? Is the dealer right about a bad turbo? I personally think the turbo will not fix the problem. Any help would be appreciated I'm tired of driving my wife's Nissan.

 

Well to my knowledge and it's pretty good, turbos are not electronic by no means sounds like they are blowing smoke up your butt, you can visually check the turbo for cracks in the fins, housing, and spin the turbine to see and feel if there is any grinding. That would be your indicators of a bad turbo. I personally don't trust dealerships I like to call them stealerships when it comes to doing work on vehicles. If your issue is like my last post with the edge having a loose wire I'd check that route first.

 

Another thing is check all your connectors for your Edge at all the connections as it could have possibly come unplugged somewhere too.

 

I don't have an edge or any programmer installed on this truck. I can make the fins scrape the housing if i push the rod over hard while turning it. When the truck is running however it is very smooth and once the engine is off the turbo will spin for several seconds with what appears to be little to no resistance and whisper quiet. I had decided to go ahead and put the new one in until thinking about the AIT code. I cant see how the two are related and it threw that code the same time the truck started this crap.

 

I'm in total agreement about the dealer. I used to think they were good for diagnostics but I'm mot sure anymore. Btw they wanted $1000 in labor to swap turbos!!!
